Every now and then, a conservation opportunity comes along that you can't pass up. The Western NY Land Conservancy (WNYLC) is currently in a race to permanently protect the Bear Lake Preserve, 311 acres of undeveloped shoreline, mature forest, and an array of critical wetland habitats linked to the Lake.To break down what makes this property so special, the guys hit the trail with WNYLC Stewardship Director Josh Balisteri. He gives them a tour of the property, discussing the history and ecology of Bear Lake, the historical and global crisis of wetland loss, and why we need to start viewing the Great Lakes ecosystem through the lens of crucial "inland coasts."Head over to wnylc.org/bearlake to check out maps of the new preserve and support their work!This episode was recorded at Bear Lake in Stockton, NY (and Pomfret, NY) on May 18, 2026.Episode Notes and LinksLucy and Bear Lake:During the episode, Bill boldly threw out a bit of local lore suggesting that WNY’s favorite daughter, Lucille Ball, once stayed at a cottage on Bear Lake. He diligently searched online for any evidence that this was true, but came up empty. Lucy did grow up on the shores of nearby Chautauqua Lake in Celoron and spent many summers during the peak of her popularity escaping to Chenango Lake in eastern NY, but there is no official record of her hiding out at Bear Lake. Sorting Out Our Flight Paths: Later in the conversation, Bill referenced Darryl McGrath’s excellent book Flight Paths: A Field Journal of Hope, Heartbreak, and Miracles with New York's Bird People and misidentified Hemlock Lake as one of the state's first eagle hacking (establishment) sites. While Bill was correct in remembering that Hemlock Lake was mentioned in the book, he was confused about the context. In reality, Hemlock Lake played a far more poignant role: it was the home of the very last known native nesting pair of bald eagles in New York State. By the late 1970s, chemical contamination from DDT had devastated the population, and that lonely Hemlock Lake pair was all that remained of our national bird in the entire

Something’s not right in the woods, at least if you’re a white-tailed deer. In this episode, the guys dig into chronic wasting disease (CWD), a strange illness reshaping deer populations in many areas of the Lower 48 (and Scandinavia!). It’s not caused by a virus or a bacteria, but it is related to mad cow disease. They break down what it is, how it spreads, what’s happening inside infected animals, and why it’s so dang hard to contain. The deer are not alright… and there’s a reason.This episode was recorded on April 23, 2026 at Walton Woods Park in Amherst, NY (a suburb of Buffalo). Episode Notes and Links·         Are there different CWD strains in a single animal? Chronic wasting disease isn’t a single, uniform pathogen. It’s more like a shifting swarm. Infected deer can carry multiple prion “strains” at once, meaning different misfolded shapes of the same protein that behave in slightly different ways. They could spread through the body differently, build up in different tissues, and cause disease at different rates. Lab experiments show this most clearly: when CWD prions are passed through model systems, what looks like one strain can split into multiple distinct variants, or reveal that a mixed population was there all along (e.g., Angers et al. 2010 PNAS; Béringue et al. 2012 Journal of Virology; Li et al. 2010 Journal of Virology). In actual deer, the picture is harder to pin down, but studies comparing prions from different tissues and individuals show real strain diversity and suggest that more than one strain can exist within a single animal (e.g., Angers et al. 2009 Journal of Virology; Moore et al. 2016 Emerging Infectious Diseases). The takeaway is that CWD behaves less like a single disease agent and more like a moving target: a cloud of protein shapes, some dominant, some hidden in the background, that can shift over time, giving the disease more chances to adapt, persist, and potentially jump into new hosts.·         Does repeated exposure to CWD reduce incubation time in deer? Repeated exposure to CWD prions does likely shortens incubation time, mainly because prion diseases are strongly dose-dependent. Higher cumulative exposure, whether from a single large dose or many smaller ones over time, can both increase the chance of infection and accelerate disease progression. Experimental studies in deer and elk show that animals exposed to higher or repeated doses tend to develop symptoms faster than those exposed once at low levels. In the wild, this likely plays out through repeated contact with contaminated environ

The Brown Tree Snake (Boiga irregularis) has wreaked ecological havoc on Guam since its accidental release in the years following WWII, playing a major role in the extinction of endemic bird species and causing trophic cascades that have rewired how the island’s forests function. But how did a population of millions come from just a handful of snakes? And how does this species continue to thrive after eliminating so much of its prey base? A soon-to-be-released study looked into the genome of this invasive species and uncovered some intriguing possibilities. In this episode, the guys welcome their special guest, Dr. Christopher Osborne, to discuss his study and its implications for species management.This episode was recorded on March 15, 2026 at Rollin T. Grant Gulf Wilderness Park in Lockport, NY, a place Bill has (jokingly) called “the armpit of WNY” despite its deep history and the fact that he’ll absolutely encourage you to check it out.Episode Notes and LinksIn the beginning of the episode, Steve said we would definitely, 100%, without doubt, cover something called Lewontin’s paradox. Well, we skipped it! The main idea behind the paradox is that genetic variation varies little among species, but population size varies massively. We would expect large populations to have a lot of genetic diversity, but we often find that they don’t. Population size doesn’t always scale with genetic diversity.

It’s gator time, folks! It seems like we should’ve already covered this topic, but, nope, this is our first ever episode on the American Alligator (Alligator mississippiensis), and we’ve got two ringers to help: Daniel returns (our Field Guide host who moved to Florida last year) and he’s joined by his mentor in all things swamp-related, Chip Campbell. Chip spent twenty years running Okefenokee Adventures, leading interpretive tours in the Okefenokee National Wildlife Refuge, and his knowledge of alligator natural history and ecology runs deep.Thanks to our Patrons, this episode is also an on-the-road joint. The guys are deep in the Florida Everglades on a multi-day paddling trip, and they take a break at camp to talk with Chip about all things alligator — with a special focus on separating gator myths from reality.And, unfortunately for those of you crushing on Steve, this one’s 100% Steve-free.This episode was recorded on Dec. 31, 2025 at Watson’s Place campsite in Everglades National Park.Episode Notes and LinksAlligators, metabolism, and the “dog comparison”During the episode, Chip mentioned a study suggesting that several alligators could be maintained on roughly the same caloric intake as a single dog. We were not able to locate a study that makes that specific numerical comparison. However, the underlying idea is strongly supported by research on alligator physiology: American alligators have extremely low metabolic rates compared to warm-blooded mammals because they are ectothermic and do not spend energy maintaining body temperature. Classic physiological work shows that adult alligators can have daily energy expenditures that are only a small fraction of those of similarly sized mammals, making informal comparisons like this directionally accurate even if the exact ratio is anecdotal rather than experimental.

Integrative and Comparative Biology, 29(3), 921–934. https://doi.org/10.1093/icb/29.3.921Freshwater “sipping” — the study behind the observation The behavior Chip describes is documented in a study by Nifong and Lowers, which examined how coastal alligators use estuarine habitats. The authors note that after heavy rainfall, a thin layer of freshwater can temporarily sit on top of saltier water, and alligators will take advantage of this by drinking f

In this episode, Bill and Steve dive into a tiny, bustling world - a world that’s hiding on the feathers of the birds we see every day. Joining them is Dr. Alix Matthews, postdoctoral research associate in the Department of Biological Sciences at the University at Buffalo, and she reveals the strange lives of feather mites — how these barely-visible hitchhikers feed and get around and whether or not they’re helping or hurting their avian hosts.This episode was recorded on September 4, 2025 at Walton Woods in Amherst, NY.Episode Notes and LinksCheck out Dr. Matthews’s website and research here.And watch a presentation on mites she did for Audubon Arkansas in October 2025.Sponsors and Ways to Support UsGumleaf Boots, USA (free shipping for patrons)Thank you to Always Wandering Art (Website and Etsy Shop) for providing the artwork for many of our episodes.Support us on Patreon.Check out the Field Guides merch at our Teespring store.

It’s part 2 of our dive into the Insect Apocalypse, with our good friend Dr. Jason Dombroskie from the Cornell University Insect Collection!In this part, Jason fills us in on the drivers of the Insect Apocalypse and - most importantly - what we can do about it.This episode was recorded on August 21, 2025 at Rattlesnake Hill Wildlife Management Area in Dalton, NY.. Episode NotesDuring the episode, we made the claim that 40 million acres of the US is lawn, and that that area is equal to all of the country’s National Parks put together. True? Well, sort of. The claim that the U.S. has about 40 million acres of lawn—roughly equal to all our national parks combined—is only partly true. A NASA-funded study led by Cristina Milesi estimated that turfgrass covers about 128,000 km² (≈31 million acres) of the continental U.S., making it the largest irrigated “crop” in the country (Milesi et al., Environmental Management, 2005; NASA Earth Observatory). Later analyses and popular summaries often round that up to ≈40 million acres (e.g., Scienceline, 2011; LawnStarter, 2023). By comparison, the total land area of all officially designated U.S. National Parks is about 52.4 million acres, while the entire National Park System—which also includes monuments, preserves, and historic sites—covers about 85 million acres (National Park Service, 2024). So while lawns and parks occupy areas of similar magnitude, lawns do not actually equal or exceed the combined area of the national parks. Is it better to mulch leaves on your lawn or leave them be? Here’s what we found: It’s generally best to mulch your leaves with a mower rather than rake or remove them. Research from Michigan State University found that mowing leaves into small pieces allows them to decompose quickly, returning nutrients to the soil and reducing weeds like dandelions and crabgrass (MSU Extension, “Don’t rake leaves — mulch them into your lawn”, 2012). Cornell University studies similarly show that mulched leaves improve soil structure, moisture retention, and microbial activity (Cornell Cooperative Extension, “Leaf Mulching: A Sustainable Alternative”, 2019). However, in garden beds, wooded edges, or under shr

The guys are back in the field with our good friend Dr. Jason Dombroskie from the Cornell University Insect Collection!Listen in as Jason leads us through fields and forests, trusty butterfly net in hand, filling us in on the so-called “Insect Apocalypse.” Are insect populations really collapsing worldwide? What do the numbers say? How bad is it, and — most importantly — what can we do about it?In this part, we head out on the trail with Jason. He introduces us to some insects we find along the way and schools us on why insects are so important, and in part two – he delves into the details of the insect apocalypse – what we know and what we don’t know. And since we feel bad that you can’t see what we got to see – we bring back a little trick we had in our last episodes with Jason – each time we find a critter listen for the sound of a camera shutter. That’s the signal to visit this episode’s page on our website – thefieldguidespodcast.com -  we’ll have photos there timestamped so you can see what we’re looking at, along with some extra info. Enjoy…This episode was recorded on August 21, 2025 at Rattlesnake Hill Wildlife Management Area in Dalton, NY.. Episode NotesSteve said he heard that there are more species of just weevils than there are of fish. Is that true? At one point in the episode Steve mentioned he’d heard there are more species of weevils than there are of fish. I looked it up, and he’s right! Scientists have described around 60–70,000 weevil species, with the real total likely over 100,000, while all the fish in the world come in at about 35,000 species. So as surprising as it sounds, Steve’s claim checks out—the humble weevil family really does outnumber all the fish.It was also mentioned that some insects are only known from a single specimen in a collection and have never been seen again in the wild. We looked for a study and found a large one from 2018 that looked at more than 800,000 insect species – it found that about one in five—around 19%—are described from a single specimen and never collected again (Lim et al., Current Biology, 2018). It really shows how much of insect diversity is still barely known.P

Part 2 of our time in the woods with naturalist Sandy Geffner. This time, Sandy leads Steve and Bill on a “hike”—though with Sandy, the word takes on a different meaning. You might not cover much distance, but you’ll travel miles in understanding: exploring ecology and hearing stories of the forest and the wildlife within it. Enjoy!This episode was recorded on July 21, 2025 at JP Nicely Memorial Park in West Falls, NY.Episode Notes and LinksSandy’s favorite books: A Sand County Almanac by Aldo Leopold and Finding the Mother Tree by Suzanne Simard. But we feel that we have to call ourselves out here because we’ve been critical of Simard’s work before and maybe we should’ve brought this up with Sandy during the episode (but we obviously didn’t have the stones).

Bill and Steve look into the Dawn Chrous, that early morning explosion of bird song that refuses to let you sleep in. And, for all you Daniel-haters out there, this episode is 100% Daniel-free (but Bill and Steve are both crying on the inside. We miss Daniel buckets, and we're betting you do, too).This episode was recorded on April 10, 2025 at the California Road Rereation Area in Orchard Park, NY.Episode Notes and LinksAre there orioles in China? Bill shared the classic Chinese poem from the Tang Dynasty (~600–900 CE) - the one called "Feelings on Awakening from Drunkenness on a Spring Day" by Li Bai, and Steve wondered:  Are there Orioles in China. Turns out that, yes, there are, and they’re more oriole-y (?) than ours! That’s because our New World orioles, like the one we’re betting you’re thinking of right now (the well-known orange and black Baltimore Oriole) belong to the family Icteridae and are not closely related to Old World orioles. Instead, they’re closely related to blackbirds and meadowlarks, fellow family members in the Icteridae. Old world orioles in Europe and Asia, on the other hand, belong to the family Oriolidae. Our orioles were named after them because of the similarities to the old world orioles in behavior, diet, and appearance, but, despite the similarities – these families are not closely related. The similarities evolved independently due to convergent evolution (when species develop similar traits in response to similar environmental pressures). So, yes, Steve, there are orioles in China, but it’s tough to say for sure which oriole Li Bai heard in his drunken stupor because Birds of China reports seven species found throughout the country, and, as we pointed out, given Li Bai’s state, maybe the bird was o

The guys return to Everglades National Park, again looking for a predator that Daniel wants to get too close to: the American Crocodile (Crocodylus acutus). Listen in as Daniel shares some research, busts croc-related myths, and Steve probably gets a little too excited about how crocs deal with salt water. Bill doesn’t have much to say, but he’s there, too. Enjoy!This episode was recorded on January 7, 2025 on the Bear Lake Trail in Everglades National Park. The last bit where the guys find the croc was also recorded in the Park, at the Flamingo Marina.Episode Notes and LinksAs promised during the episode, Steve is looking into how crocs process and excrete excess salt. As soon as he gets to the bottom of it, we’ll share it here.In the meantime, here’s what Bill found when he asked DeepSeek: Crocodiles, like many other marine and estuarine reptiles, have specialized salt glands to help them excrete excess salt from their bodies. These glands, known as salt glands or lingual glands (located on their tongues), actively transport salt ions (primarily sodium and chloride) from their bloodstream into the gland ducts. The salt is then excreted as a concentrated saline solution, which is expelled from the body.Crocodiles do not chemically change the salt (sodium chloride) into something else. Instead, they filter and concentrate it, allowing them to maintain proper electrolyte balance in their bodies, especially when living in saltwater environments. This process is crucial for osmoregulation, as it prevents dehydration and helps them survive in both freshwater and saltwater habitats.In summary, crocodiles excrete salt in its original form (sodium chloride) but in a highly concentrated solution, rather than transforming it into a different substance.Sponsors and Ways to Support UsGumleaf Boots, USA (free shipping for patrons)Thank you to Always Wandering Art (Website and Etsy Shop) for providing the artwork for many of our episodes.<p class=""

This month, we head to the tropics and meet the Blue Iguana of the Cayman Islands! This endangered lizard is found nowhere else on the globe save for the island of Grand Cayman in the Caribbean, and just two decades ago, it’s likely there were fewer than 25 animals remaining in the wild. This was a species that was functionally extinct, but thanks to the herculean efforts of a dedicated group of people, the Blue Iguana (Cyclura lewisi) has been brought back from the brink, with over 1000 iguanas now roaming the dry, rocky forests of Grand Cayman. In July of 2024 Bill traveled there to interview Fred Burton, the man many people credit as the main driver behind the effort to save this endemic species.This episode was recorded on July 25, 2024 at the Queen Elizabeth II Botanic Park, North Side, Grand CaymanEpisode Notes and LinksFind ourt more about conservation of the Blue Iguana by visiting the National Trust for the Cayman Islands.If you want to support efforts to help the Blue Iguana, you can donate here.Check out Fred’s book, The Little Blue Book: A Short History of the Grand Cayman Blue IguanaIf you ever find yourself in Grand Cayman, we can’t recommend enough that you visit the Queen Elizabeth II Botanic Park, home to the Blue Iguana captive breeding program.Sponsors and Ways to Support UsGumleaf Boots, USA (free shipping for patrons)Thank you to Always Wandering Art (Website and Etsy Shop) for providing the artwork for this episode.Support us on Patreon.<a href="https://the-field-

How hard is it to reintroduce species to a tropical island? Turns out, pretty hard! But it’s so worth it. The rewilding of the Galapagos island of Floreana will make it the largest tropical island ever to be rewilded. Researchers have spent over a decade meticulously planning for the reintroduction of the iconic Floreana Giant Tortoise (Chelonoidis niger niger). Once thought to be extinct, this species, along with eleven other locally extinct endemic animal species, are part of a reintroduction project that has involved the massive task of eradication of introduced predators, as well as the purposeful inclusion of the local population throughout the planning process. This month, Bill and Steve are completely out of their depth, discussing the project with three staff members from Fundación Jocotoco, one of the organizations leading the charge to Rewild Floreana.This episode’s special guests are Paola Sangolquí, Jocotoco’s Galapagos Program Marine Coordinator, Julieta Muñoz, Conservation Strategy Manager, and Jajean Rose-Burney, the Director of Jocotoco US.The episode was recorded in New York, NY on September 23, 2024.Episode Notes and LinksVisit Fundación Jocotoco’s Rewilding Floreana website.Here’s where you can donate to support the project.

This month, Daniel leads the guys into uncharted waters for the podcast…that’s right, it’s our first-ever episode about fish! The Great Lakes salmon fishery is one of the greatest angling spectacles in the US. Large predatory salmon, native to the Pacific Northwest, are stocked in the Great Lakes region to maintain a world class fishery and control invasive baitfish. The undisputed monarch among these stocked species? The appropriately named King Salmon (Oncorhynchus tshawytscha). While they are fished for year-round, the action heats up when mature King Salmon run (well, they swim, but that’s what it’s called) up the creeks and rivers where they were born or stocked each fall. The salmon run attracts anglers from all over the country, fostering a multi-million dollar industry and countless memories. But what is with all the excitement? Why are Pacific salmon even put here? Dare we even ask, should they be here? In this episode, the guys venture to a popular salmon fishing spot near Lake Ontario and reel in the story of one of the most consequential actions in fisheries management history.  This episode was record at the Burt Dam Fishermen’s Park in Olcott, NY on October 8, 2024.Episode Notes Daniel mentioned the scientific name and meaning for the Coho Salmon: Oncorhynchus kisutch.  But he failed to mention that the Chinook or King Salmon’s scientific name, which is Oncorhynchus tshawytscha. Oncorhynchus as mentioned in the episode from Greek origin, loosely means “hooked snout,” referring to the “kype” these salmon develop. Tshawytscha is derived from a Russian name for the King Salmon, like how kisutch is derived from a Russian name for the Coho Salmon.Chinook Salmon (Oncorhynchus tshawytscha) are also known as King salmon.  Chinook and King are used interchangeably in the episode, as Daniel can’t seem to settle on a common name he likes.  As mentioned in the episode, “King” comes from the fact that this salmon species is the largest salmon species in the world.  Steve asked Daniel what “Chinook” means, and he did not know.  After further research, it is found that the word Chinook is derived from the Chinookan people.  This includes several groups of indigenous people of the Pacific Northwest, where the Chinook Salmon is native. And what about Coho Salmon? “Cohos” is a word in one of the dialects of the native peoples of the Pacific Northwest with an unknown meaning, possibly the name for the fish itself. Depths of the Great LakesThe books the guys mentioned were Dan

If we want to help wildlife, we need to know when and where they’re moving on the landscape. Dr. Scott LaPoint has spent his career researching just that. When our recent episode on fisher cats left us with a lot of questions, we figured who better to help us out than Dr. LaPoint. He was kind enough to join Daniel and Bill for a hike, sharing his expertise and his amazing ability to communicate science with enthusiasm, humor, and clarity.

Pinesap (Monotropa hypopitys) is a goofy little plant that parasitizes fungi and can often be found beneath pine trees. It is not the sap of pine trees like Daniel thought. In this episode, Bill leads the discussion about the complex relationships between pinesap, its fungal host, and the tree species the fungi has a symbiosis with. Garlic mustard (Alliaria petiolata) also makes a guest appearance! Join the guys as they get caught in a sudden rainstorm and learn about this amazing plant. This episode was recorded on July 14, 2024 at Chestnut Ridge County Park in Orchard Park, NY.Episode NotesBill brought up whether or not Pinesap (Monotropa hypopitys) should be in it’s own genus, Hypopitys. Steve asked some overly complicated questions to clarify whether or not he should believe it. With a quick search, at least Braukmann et al. (2017), Liu (2020), Shen et al. (2020), and Freudenstein & Broe (2024) found that Hypopitys groups distinctly from Monotropa in its phylogeny (i.e., evolutionary history). Hypopitys is more closely related to other genera, such as Pityopus, for example, than other species in the genus Monotropa. Steve is satisfied with this quick dip into the lit.Thank you to Always Wandering Art (Website and Etsy Shop) for providing the artwork for many of our episodes!

Fishers (Pekania pennanti) are a predator species reclaiming much of its former range in the northeastern US, but, as sightings become more common, so do stories of what fishers (AKA fisher cats) are up to. Are they eating young turkeys and housecats? Are they the animal you hear screaming from the woods at night? Why did one study find fisher toes and feet in the stomachs of other fishers?! This episode, the guys are on the trail - both literally and figuratively - tracking down the life history of this elusive member of the weasel family.This episode was recorded on April 24, 2024 at Hunters Creek County Park in East Aurora, NY.Episode NotesAre skunks weasels? The guys debated whether or not skunks are members of the weasel family, with Daniel saying that they were not. Turns out he was correct. The Canadian Encyclopedia states:Skunks were previously considered as part of the weasel family (Mustelidae) but DNA research has placed them in their own family, Mephitidae.What do you call a genus that contains only a single species?

Who doesn’t love an eclipse? Apparently, wildlife has very mixed feelings about the whole affair. This month, the guys prepare for the upcoming 2024 total eclipse by looking into the research around how animals react to the moon photobombing the sun for a few minutes. The reactions are not universal, but they are varied. And trying to figure out what the animals are up to makes for a fascinating listen. This episode was recorded on March 20, 2024 at Reinstein Woods Nature Preserve in Cheektowaga, NY.Episode NotesBill mentioned that “wind is air moving between temperature differences.” When listening back to the episode during editing, he worried that maybe he was wrong on that. Looking it up, he did find some websites claiming that wind is due to differences in air pressure and that temperature has little to do with it, but it turns out that’s not quite true either. According to the good people at NOAA (The National Oceanic and Atmospheric Administration, the organization referred to in this episode), the answer is both. Their short answer to “what makes wind?” is that it’s the movement of gases from high-pressure areas to low-pressure areas. BUT, they go on to say that the main cause of wind is actually temperature. More specifically, it’s differences in temperature that lead to different air pressures.It all starts because as the sun warms up the air on the Earth, it does so unevenly. Because the sun hits different parts of the Earth at different angles, and because Earth has oceans, mountains, and other features, some places are warmer than others. Because of this, we get pockets of warm air and cold air.Since gases behave differently at different temperatures, that means you also get pockets with high pressure and pockets with low pressure. Generally speaking (and notice we said generally), in areas of high pressure, the gases in the air are colder and more crowded. In low pressure zones, the gases are warmer and a little more spread out. And this is why wind happens. Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.Bill stated that perigee when the moon is farthest from the Earth. WRONG! The point i

Florida Panthers (Puma concolor couguar) are a distinct population of pumas that live predominantly in southwest Florida. Pumas used to roam the entire United States, but habitat loss and overhunting in the 1800’s and early 1900’s caused them to disappear from much of their range. Every breeding population of pumas East of the Mississippi river vanished, except for one. South Florida, due to its wild and swampy nature, was able to thwart human development just enough for its inhabiting pumas to narrowly avoid oblivion. These surviving pumas, or Florida Panthers, represent the resiliency of wild south Florida. The decades since their near extinction have been filled with controversy, conservation, and politics. This iconic cat still has many challenges to face, and with only 200 or so remaining in the wild, their future is uncertain.  Daniel was first introduced unofficially to this animal during his first trip to Everglades National Park in 2017. The Florida Panther and the swampy, remote areas in which they are found captivated Daniel’s imagination. Every subsequent trip to the Everglades and southwest Florida had at least some time dedicated to searching for this cat, all to no avail. In January 2024, after spending months preparing and researching, Daniel embarked on a five-day solo trip in the backcountry of the Big Cypress National Preserve, with the sole objective of finally crossing paths with a panther.But what exactly IS a Florida Panther? Are they only found in Florida? Are they black? What is the difference between a Florida Panther and a mountain lion? And of course… do they eat people?!  Luckily, Bill was able to meet Daniel in south Florida to record an episode about the Florida Panther and tackle the questions and misconceptions that leave this cat shrouded in mystery.  This episode was recorded on January 8th, 2024 at Everglades National Park in Homestead, FL.   Episode NotesWhen Daniel was talking about Florida Panther size, they were described as smaller than other pumas out west. It should also be noted that while they do fall to the bottom of the size and weight scale of pumas in North America, the populations of pumas closer to the equatorial rain forests in South America are even smaller. This reinforces the notion discussed in the podcast that pumas in colder climates or higher elevation tend to be larger than pumas in warmer climates and lower elevation.  Also, Bill asked Daniel what their life span was, and Daniel was not sure.  Bill guessed 20-30 years. According to Florida Fish and Wildlife Conservation Commission, “Panthers can live up

Part 2 of our Timber Rattlesnake episode. If you haven’t listened to part 1, go and do that. We’ll wait right here for you. The episode was recorded on December 7, 2023 at Hunters Creek County Park in East Aurora, NY.Episode NotesWhen the guys discussed the different types of snake teeth, Steve wondered if the word solenoglyphous, which refers to snakes with two large, hinged fangs (like the Timber Rattlesnake), has any relation to nightshades, which are plants in the genus Solanum. Bill could have cleared it up right away if he had been sharp enough to notice the difference in spelling. Upon getting home and doing some research, he found that the root soleno is Greek, and it means a tube or pipe. This makes sense given that solenoglyphous snakes have large, hollow fangs. The second part of the word - glyphos – means to cut or carve, so solenoglyphous could be taken to mean “hollow fangs that cut or carve”.  Incidentally, Bill also tried to look up what Solanum means. He found many circular references – sites that said Solanum means nightshade, and that nightshade means Solanum. The most promising reference he found said that Solanum possibly stems from the Latin word sol, meaning "sun", referring to the nightshades love of sun, maybe?      Steve asked if proteroglyphous fangs (the smaller, unhinged fangs in species like the Coral Snake) are hollow. Bill thought they might be, and he was right. A little internet digging led to this blog post that had a handy-dandy cross-section of the different types of snake teeth. Can owls identify venomous snakes? While we couldn’t find any studies, or even any general articles, that covered this specific question, we did find an interesting study that looked at venom resistance in a variety of animals. The research “analyzed the molecular resistance against cobra venom and found considerable differences in resistance between animas groups.” It showed that several mammal species, such as the Honey Badger and the Asian Mongoose, independently evolved resistance to cobra venom, but the snake-eating bird species looked at showed no resistance. The study’s authors hypothesized that "…the resistance is redundant: There is no selection pressure for it. Birds have feathers, scaly legs, excellent vision, are very intelligent, and are very agile. The snakes don't stand a chance against all these adaptations, so birds just don't need to be resistant." So

Love ‘em or hate ‘em, we wager you’ll enjoy this dive into the shiny (not slimy) world of rattlesnakes. This episode, the guys take a close look (but not too close) at the Timber Rattlesnake (Crotalus horridus), trying to show how it’s not out to kill you and also finding out how it ended up on the “Don’t Tread On Me” flag. Plus, they introduce the newest field guide, Daniel! The episode was recorded on December 7, 2023 at Hunters Creek County Park in East Aurora, NY.Episode NotesOne intriguing question that came up was, “If rattlesnakes that rattle call attention to themselves and get killed by humans, does this mean we’re inadvertently selecting for rattlesnakes that don’t rattle and creating populations of silent rattlers?” It’s an idea that sounds logical, but, as the guys have discovered on many other occasions, that doesn’t mean it’s true. After some digging through a variety of sources, the guys could find zero research-based evidence supporting the idea of this phenomenon. There are news stories that promote it, but all the ones that do seem to base their info on anecdotal accounts. The most interesting source - and the one the guys found to be the most skeptical (in the best sense of the word) - was from Rattlesnake Solutions LLC, an Arizona-based rattlesnake removal and consulting service. This is ironic because Bill went out of his way during the episode to caution listeners to be wary of such sites, but this one seems to genuinely want to not only share solid info about rattlesnakes but also to combat misinformation. In a post called, “Are rattlesnakes evolving to rattle less, or losing their rattles?”, they explained:Rattlesnakes don’t often rattle in the wild, even when there’s someone looking at them. This is a great example of confirmation bias. If you hear that rattlesnakes aren’t rattling any longer, and you then see a rattlesnake just sitting there and not rattling, this can serve as confirmation that the rumors are true. You then tell others this is the case, having first-hand experience on the matter, comment on Facebook, etc. Just like that, you’ve become the latest node in the spread of nonsense without realizing it.This can be even more confusing for long-term hikers with a lot of experience, who report seeing this phenomenon over time (decades even), where rattlesnakes used to rattle but now most of the rattlesnakes they see don’t: therefore the myth is true. What these anecdotes really look like is something much more simple to explain. Ove

This month, Bill and Steve visit Floating Fen, although some might call it a bog, or is it a swamp? Thankfully, they’re joined by Erik Danielson, Stewardship Coordinator of the Western NY Land Conservancy (WNYLC), who schools them on the difference between these wetlands. Erik and the WNYLC are trying to preserve Floating Fen, a property home to a unique wetland, extraordinary life, and a diverse forest. Erik guides Bill and Steve through the fen, discussing just what makes a bog a bog and a fen a fen, as well as what makes these peatlands such amazing habitats.The episode was recorded on June 17, 2023 at the Floating Fen near Fredonia, NY.Episode Notes Please comment below if you notice any mistakes or unanswered questions in the episode.Links to the Western NY Land ConservancyVisit the website of the Western New York Land Conservancy to find out more about their vital conservation efforts.Find out more about the Floating Fen, including the efforts to preserve it.Explore the WNY Land Conservancy’s Western New York Wildway, their ambitious new initiative to create an extensive series of protected lands that connect the vast forests of northern Pennsylvania to the Great Lakes, central NY, the Adirondacks, and beyond.Other Episode-related LinksA one-page primer on Conservation EasementsThe book that Erik mentioned was A Focus on Peatlands and Peat Mosses by Howard (not Viktor) Crum.The Wildlands Network - the group responsible for initially identifying the four “Continental Wildways” traversing the Pacific and Atlantic coastlines, the Canadian Boreal Forest region, and the “Spine of the Continent” between Alaska and Mexico.Bill’s article about Mike Radomski, Outside Chronicles, and the WNY Hiking ChallengeSponsors and Ways to Suppor

The Bald Eagle (Haliaeetus leucocephalus) is a rare example of a species humans managed to pull back from the brink of extinction by getting off our collective asses and doing some stuff. Already decimated by hunting and habitat loss, the post WWII enthusiasm for spraying the chemical DDT on just about everything sent Bald Eagle populations into freefall. That is, until Rachel Carson published Silent Spring in 1962 and sensibly said, “Hey, maybe we shouldn’t go through pesticides like beer at a frat party. Maybe let’s use as little as needed?” We’re paraphrasing, of course, but, eventually, DDT was banned in the US, the Bald Eagle was placed on the Endangered Species list, and our national bird was on the road to recovery. This is the story told about Bald Eagles and DDT. But a few out there question this narrative, claiming that DDT wasn’t a big problem for eagles and that banning it caused billions of unnecessary deaths because it prevented DDT’s continued use in the fight against malaria. These claims are mostly nonsense, drudged up by folks who hate regulations, but looking into them makes for an interesting ride. Join the guys as they find out…DUN DUN DUN…what THEY don’t want you to know about Bald Eagles.

They’re hard-working, tail-slapping, tree-cutting machines, and they’re one of the greatest wildlife recovery stories in North America: Castor canadensis, the North American beaver. And, as if all that weren’t enough, apparently their rear ends produce an oil that’s vanilla-scented. Join the guys as they keep their puns and innuendos in check and dive into beavers! This episode was recorded on January 28, 2023 at the Beaver Meadow Audubon Center in North Java, NY.  Episode NotesBeaver anal glands – which gland is used for which? There was some confusion over the beaver’s anal glands and the oils they produce. Some sources stated that beavers have two anal glands that produce oil for waterproofing - the oil that smells like motor oil in male beavers and rancid cheese in females) and two more glands that produce oil (castoreum) for marking their scent mounds. Some sources, however, said the waterproofing oil was also used for scent marking. So, what gives? With a little more research, Bill discovered that he misspoke during the episode. Beavers have two anal glands that produce the waterproofing oil, and two castor sacs (not glands, although they’re often referred to as such) that produce castoreum, the oil used for scent-marking. All four structures are located near each other, between the pelvis and the base of the tail. Here’s a paper that explains it all. Click the “pdf viewer” tab for a format that is easier to read.Steve recalled hearing how parts of whales were used in perfume production. He was right! “Ambergris [is] a solid waxy substance originating in the intestine of the sperm whale (Physeter catodon). In Eastern cultures ambergris is used for medicines and potions and as a spice; in the West it was used to stabilize the scent of fine perfumes.” From Britannica.comWhen discussing the study that looked at how beaver dams fare during floods, Bill cited that, in one study, 70% of beaver dams remained intact during a flood event. Steve then pointed out that 30% of the dams failing seemed to lend at least some credence to the anecdotal records of beaver dams being unreliable at mitigating flood impacts. If Bill was a quicker thinker, he would have realized that he had JUST SAID that even though 30% of the dams in the study did not remain completely intact, the researchers found that many

This month, Bill and Steve geek out over insects! And it’s because they were lucky enough to have an even bigger insect geek invite them on a field trip. Jason Dombroskie is the collection manager and director of the insect diagnostic lab at Cornell University. His invite to take the guys mothing in July of 2022 turned into a marvelous, day-long adventure:In part one, you’ll hear the guys meet up with Jason for a tour of his property and an interview delving into Jason’s background and what it’s like to be a professional entomologist (it involves studying lots of insect genitalia, among other things). We follow that up with a behind-the-scenes tour of the Cornell University Insect Collection - an assemblage spanning over 7 million insect specimens representing about 200,000 species, or roughly 20% of the world’s described insect fauna.

Have you ever heard a mockingbird imitate a blue jay? How about a seal imitating a Maine fisherman? This month, the guys explore what happens when animals make sounds they’re not supposed to: the wild world of vocal mimicry. Birds imitate chainsaws and car alarms, elephants speak Korean; what’s going on? With a special focus on one of the bird world’s best known mimics - the northern mockingbird (Mimus polyglottos) - the guys delve into the research trying to explain why animals - especially birds - feel the need to engage in the wildlife equivalent of, “I know you are, but what am I?”  Episode NotesSteve wondered about the similarity between the scientific names of the northern mockingbird (Mimus polyglottos) and monkeyflowers (in the genus Mimulus). Turns out that both refer to mimicking; the mockingbird (whose scientific name means ““many-tongued mimic”) imitates the sounds of other species, and the monkeyflowers have flowers that, at least to some, seem to have grinning faces resembling those of monkeys.Bill mentioned that the viceroy butterfly (Limenitis archippus) is often mistakenly cited as an example of Batesian mimicry. What’s up with that? Here’s what the University of Wisconsin has to say about it: “Ecologists have long preached that Viceroys have enjoyed a Batesian “Get-out-of-Jail-Free” card due to their resemblance to the toxic Monarch butterfly (Batesian mimicry—the harmless imitating the harmful). Monarchs are poisonous because their caterpillar host plant, milkweed, contains harmful cardiac glycosides. Recent research suggests that because willow leaves are very bitter, the Viceroy may be almost as distasteful as Monarchs. In that case, Monarchs and Viceroys are mimicking each other, each cashing in on the other’s bad reputation (Mullerian mimicry).”Check out episode 34: The Downy-Hairy Game for more info on Batesian and Mullerian mimicryThe guys wondered, “Are there any large passerines (songbirds/perching birds)?” The largest seem to be in the raven family; “The heaviest and altogether largest passerines are the thick-billed raven and the larger races of common raven, each exceeding 1.5 kg (3.3 lb) and 70 cm (28 in). The superb lyrebird and some birds-of-paradise, due to very long tails or tail coverts, are longer overall.” <a href="https://en.wikipedia.org/wiki/Passerine#:~:text=The%20heaviest%

Black Walnut (Juglans nigra) is a tree well-known for its ability to negatively affect other plants growing nearby, a phenomenon known as allelopathy. But is Black Walnut really as allelopathic as the Internet would have you believe? In this episode, the guys go nuts: delving into this question and many other facets of the fascinating (and tasty?) Black Walnut, including an on-air tasting of Black Walnut syrup. Enjoy! This episode was recorded on May 11, 2022 at the Beaver Meadow Audubon Center in North Java, NY.Episode NotesThank you to listener Mark Carroll for giving us the idea for this episode and providing the paper on which much of it was based.Is Black Walnut wind pollinated? Bill mentioned during the episode that he thought the flowers were insect pollinated. He was WRONG! According to Floral Biology And Pollination Of Eastern Black Walnut, a publication by the National Forest Service, “Walnut trees are wind-pollinated and classified as monoecious; male and female flowers are on the same tree, but separated from each other.” Bill stands by his assessment, however, that the distinctive, seldom-seen flowers are worth checking out. This page provides some nice pictures; scroll down to see both the male and female blossoms. The female flowers look like milkweed pods with a sea anemone stuck on top!What is the correct measurement of diameter at breast height (DBH)? Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. Tree trunks are measured at the height of an adult's breast; in many countries, DBH is measured at approximately 1.3 m (4.3 ft) above ground, but in the US, DBH is typically measured at 4.5 ft (1.37 m) above ground. Source: https://en.wikipedia.org/wiki/Diameter_at_breast_height Does Steve know about honeysuckles? Steve claimed that honeysuckles (Lonicera sp.) with a hollow pith are not native to eastern North America and that the ones without a hollow pith are native. According to Iowa State University, “Twigs of all species can be hollow. However, the twigs of native species tend to be less hollow with a white pith whereas the exotic species are more obviously hollow with a brown pith.”Are there other plants with a chambered pith? </str

What’s dark and slimy and over two feet long? It’s an Eastern Hellbender! This aquatic giant salamander, endemic to the eastern and central US, is the largest amphibian in North America, often weighing in at over 4 lbs.! The hellbender (Cryptobranchus alleganiensis) is, not unlike Steve, secretive and slimy but also fascinating. Join the guys for one hell of an episode learning about this rare and disappearing denizen of fast-moving streams. This episode was recorded on January 22, 2022 at Chestnut Ridge County Park in Orchard Park, NY.Episode NotesBill said that the Kinzua Bridge was about 300 feet long, but he was mistaken. The bridge was about 300 feet high. The length was 2,053 feet. When Bill was talking about the white tips on hellbender toes, he mistakenly said that hellbenders have “fingers”. D’oh! Bill understand that salamanders don’t have toes, but he wants everyone to know he was using the term in a cutesy way.Steve mentioned his friend Zachary Cava and Zack’s research into hellbenders. Bill was able to track down Zack’s study! Full citation below under “Works Cited”.Around the 20:50 mark, Steve wonders if there is an ecological concept or law stating that larger species tend to go extinct more quickly than small species. After recording, Bill did some searching but could not find any specific law. Anyone out there that knows of one? Please get in touch with us!Bill gave a quick and somewhat vague definition of siltation. Here’s a more complete definition: Siltation refers both to the increased concentration of suspended sediments and to the increased accumulation of fine sediments on [waterway] bottoms where they are undesirable.

Jewelweed. Spotted touch-me-not. Orange Balsam. It’s a plant known by many names, and, even if you don’t recognize any of them, you’ve probably popped one of its exploding seed pods. A favorite of hummingbirds and nature-lovers young and old, it’s a species with many stories to share. Listen in as the guys dive deep into the jewelweed patch, eating some seeds, trying to find the source of the “jewel” in jewelweed’s name, and getting to the bottom of the age-old claim that jewelweed is a cure for poison ivy. This episode was recorded on September 26, 2021 at Birdsong Park in Orchard Park, NY  Episode Notes:Which species is more common in North America: yellow (aka pale) jewelweed or orange jewelweed? While it may vary from place to place, orange jewelweed seems to be the more common species. Nearly every site we visited referred to it as “common” or “more common” and to the yellow jewelweed as “less common”. Orange jewelweed’s North American range is also broader than yellow jewelweed’s (yellow is absent from most of the Gulf states and most Canadian provinces). When do the Witch hazel seeds explode out of their capsules? Steve and Bill were both confused on the timing. Witch hazel (Hamamelis virginiana) is a forest understory tree that blooms in the fall. The seeds take a year to develop and are forcibly expelled (because of dehiscence) from the seed capsules the following fall or winter. Check out our episode on witch hazel!Are there any plants that produce only cleistogamous (closed, self-pollinating) flowers? Not that we could find. Most sources make reference to the fact that cleistogamous flowering is a behavior that appears to have evolved to ensure reproduction under unfavorable conditions. These conditions usually limit or prevent cross pollination of the typical, chasmogamous (open) flowers.   How many species of jewelweed do we have in North America? The Lady Bird Johnson Wildflower Center lists 4 species of Impatiens native to North America. I. capensis and I. pallida are the ones found in the east (although, as mentioned in this episode, some sources list I. capensis as native in the Pacific northwest, as well). Five nonnative Impatiens species have also been introduced t

This month, Bill and Steve look into the fall and (potential) rise of the American chestnut (Castanea dentata), and they’re joined by Erik Danielson, Stewardship Coordinator of the Western NY Land Conservancy. The Conservancy recently embarked on an effort to acquire the Allegany Wildlands, a unique piece of property that harbors, among its many abundant ecological treasures, remnant American chestnuts. Erik guides Bill and Steve through the property, and, in part 1 of this episode, they discuss the history of the chestnut and the blight that caused its downfall. In part 2, they share how past and present research come together to create a realistic plan for bringing the American chestnut back. Throughout both parts, Erik shares how the Allegany Wildlands fit into the Conservancy’s ambitious effort to create the Western NY Wildway, a network of connected protected lands stretching from Pennsylvania to the Great Lakes and beyond.

This month, the guys set out to discover if daddy longlegs really are the most poisonous spider in the world, but, along the way, they uncover a fascinating array of arachnids and adaptations in the group known collectively as harvestmen. Join them for some mythbusting and a deep dive into the little-known order of arachnids called Opiliones.Episode Notes Steve referred to the American toad as Bufo americanus, and Bill agreed. But they were both wrong because its Latin name has been changed to Anaxyrus americanus.At one point, Bill made a comment where he seemed to be saying that all reptiles have teeth. They do not. He wants to clarify that he was speaking specifically about snakes. What he should have said is “Most snakes have teeth, but not all snakes have fangs.”Steve mentioned that he didn’t know much about Dick Walton, so we looked him up! Turns out Dick Walton is a naturalist and teacher living in Concord, MA. He considers himself a generalist but has focused on birds, butterflies, dragonflies, solitary wasps, and jumping spiders. He coauthored Peterson’s seminal Birding By Ear audio field guides, the go-to guide for budding birders in the pre-app era. Check out his work at http://www.rkwalton.com/ The guys have great respect for his work and hope that Mr. Walton was not offended by their joking around in this episode.. What is the origin of the name “daddy longlegs”? No one seems to know for sure, but some sources point to the book, Daddy-Long-Legs, a 1912 novel by the American writer Jean Webster. But the book, as far as we can tell, has nothing to do with arachnids. So, we’re still scratching our heads on that one.Steve wondered if crane flies are dipterans – they are! Also, during this episode, Steve had a couple questions about the mouth parts of dipterans (flies) and hemipterans (true bugs):Do all dipterans have sucking mouth parts? Yes! “Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. “ from WikipediaHow are wheel bugs killing? The wheel bugs is a species of assassin bug and is a True Bug (Order Hemiptera). “Most hemipterans feed on plants, using their sucking and piercing mouthparts to extract plant sap…but some hemipterans such as assassin bugs are blood-suckers, and a few are predators” from Wikipedia

The northern flicker (Colaptes auratus) is a common bird that has some exceptionally uncommon behaviors. Unlike most bird species, male flickers take an equal share of egg incubation and feeding, and, in up to five percent of females, a lady flicker will take up with two mates - an older male and a younger male - raising young in two different nests at the same time. In addition, flickers will sometimes lay their eggs in the nests of other flickers, a behavior called intraspecific brood parasitism, another habit rarely seen in birds. Join the guys as they delve into studies exploring the wild and swinging world of northern flicker reproduction.This episode was recorded on May 11th, 2021 at Chestnut Ridge Park in Orchard Park, NY. Episode Notes:Bill fully realizes that he mispronounced monogamous as monogyoumous. He doesn’t know why he did this, but he is appropriately embarrassed about it. Bill and Steve were both amazed to learn that belted kingfishers nest in burrows. Find out more here.At one point in this episode, Bill wondered about all cavity nesting birds having pure white eggs. They do not, and this article provides a nice overview of egg coloration in cavity-nesting species.Around the 32:40 mark – Bill said that of the bird species that have biparental care, 90% have extra pair paternity (EPP), and, in describing it, he said that it occurs when a female mates with another male outside her pair bond, but, to be clear, both sexes can engage in EPP. Steve asked about their longevity. Some info from one of Dr. Wiebe’s studies: Flickers have a relatively fast life history with an annual apparent mortality rates of 60%. The rate doesn’t vary with age. A 2006 study looked at mortality rates of male and female flickers over a 6-yr period and observed only 1-2 birds out of every 300 adults were 7 or more years old. There was no significant differences between male and female survival rates for the general population. The oldest known flicker was 9 years, 2 months old. The New World blackbird family is Icteridae.Why are these birds called flickers? As best as we can tell from a quick google search, the name is another effort to mimic their call - flicka flicka flicka. </p

This winter (2021) marked the first time a Snowy Owl (Bubo scandiacus) was spotted in New York City’s Central Park in 130 years. Why was it there? Where did it come from? Since 99.9% of the population immediately just thinks of Harry Potter when Snowy Owls are mentioned, the guys wanted to cast the proverbial “Lumos!” and shed some light on the subject. Join them and guest Daniel Mlodozeniec (photographer and naturalist) as they delve into the Snowy Owl’s ecology in part 1. Then, in part 2, come along as they look into the research behind what drives Snowy Owl irruptions, those irregular migrations that cause Snowies to end up in Central Park and even in places like Bermuda and Hawaii! This episode was recorded on February 1, 2021 in Buffalo, NY at the Erie Basin Marina (part 1) and Tifft Nature Preserve (part 2).

Then, in part 2, come along as they look into the research behind what drives Snowy Owl irruptions, those irregular migrations that cause Snowies to end up in Central Park and even in places like Bermuda and Hawaii! This episode was recorded on February 1, 2021 in Buffalo, NY at the Erie Basin Marina (part 1) and Tifft Nature Preserve (part 2).

Now that Bill’s done droning on about animals, we can finally talk about PLANTS! and CARNIVOROUS plants at that. Steve reviews carnivorous plants in general and then breaks into examples of carnivorous plants that have evolved to eat poop: Roridula spp. in South Africa, Sarracenia purpurea in North America, & Nepenthes spp. in Southeast Asia. 00:00 - Intro02:00 - Carnivorous plant review14:20 - Roridula spp. & Pameridea spp.23:10 - Sarracenia purpurea & its inquilines26:00 - Gumleaf USA ad28:35 - Nepenthes lowii, N. macrophylla, N. raja & mountain tree shrews36:45 - Nepenthes hemsleyana & Hardwicke’s Woolly Bat40:10 - Nepenthes bicalcarata & diving/swimming ants45:05 - Concluding remarks46:20 - OutroImage credit:"Nepenthes raja, eine freischfressende Kannenpflanze.

With the high-end guests we’ve recently had on, we’re concerned that the podcast is getting a bit too classy. So, this month, we’re getting down and dirty, delving into the delightful topic of defecation. Specifically, animals that eat poop. We know, it seems gross. We thought so, too. But once we started exploring this surprisingly common behavior (called coprophagy), we were amazed at what we uncovered!

Ep. 47 - Field Trip!: Exploring the Roger Tory Peterson Institute (Part 2) The Field Guides Download Welcome to part 2 of our field trip to the Roger Tory Peterson Institute. In this segment, Bill and Steve take a hike with Twan Leenders, Senior Director of Science & Conservation at the Institute. Twan has had a career in conservation that deserves to be made into a movie. From researching wildlife in the treetops of Central American rainforests to corralling ornery spiny softshell turtles in post-industrial rivers, Twan’s stories, as well as his personal philosophy on science communication, make for a fascinating listen. Enjoy!Links:Find out more about the famed entomologist Terry Erwin. Bill mentioned the journal called The Ecological Citizen.

Visit the Roger Tory Peterson Institute’s website to find out more about the site, events/exhibitions, and the good work they are doing.Steve and Arthur discussed the hellbender head-start program, and the question came up about whether it was connected with the Buffalo Zoo. Here’s what we found:“The “hellbender head-start program” is a collaboration between the Bronx Zoo, the New York State Department of Environmental Conservation, and the Buffalo Zoo. The snot otters were hatched at the Buffalo Zoo in October 2009 and raised at the Bronx Zoo’s Amphibian Propagation Center.” You can find more info here.Arthur mentioned the recent renaming of a bird. He was referring to the McCown’s Longspur (Rhynchophanes mccownii). It’s common name was recently changed to the Thick-billed Longspur.

During the editing process for this episode, Bill shared some posts about this species via social media. Several listeners commented that, in an effort to acknowledge problematic botanical names, many sources now refer to this plant as Ghost Pipe. So, although it was too late to re-record the episode, Bill altered these notes to reflect the name change.Several times in the episode, Steve and Bill wondered if a stand of Monotropa uniflora was composed of separate plants growing closely together or if it was a single plant with multiple stalks rising from a common rootstalk. In doing follow-up research, Bill could not find a conclusive statement, but in going through pictures of herbarium specimens, drawings of harvested plants, and numerous descriptions, every instance showed each Ghost Pipe stalk having its own, single bundle of roots at its base. So, for now, Bill is going out on the proverbial limb and saying that each stalk is an individual plant.The guys questioned whether Beechdrops (Epifagus virginiana) was in the Ericaceae family, along with Ghost Pipe, and Steve went on to say that he thought it might be in the Broomrape family – Orobanchaceae. He was correct!Bill mentioned that Steve is now a published researcher. He was one of the authors on a paper looking into how plants evolve certain chemicals. Check out an article about the paper here, and here’s a link to the paper, itself.Bill mentioned that, although Monotropa uniflora seems extraordinary because it lacks chlorophyll, “there are some 3000 species of non-photosynthetic vascular plants in the plant kingdom (about 1/2% of all vascular plants). Steve wondered aloud if this number was greater than all the gymnosperms out there (non-flowering plants, like pines). Steve was correct again! There are roughly 1000 extant species of gymnosperms.Steve questioned what you call an animal that feeds on sap. According to Wikipedia, it’s a gummivore. Gummivores are a hybrid class of omnivores that defines a group of animals whose diet consists primarily of the gums and saps of trees (about 90%) and bugs for protein.Steve mentioned that there are trees in the Gentian family, and then he went on to joke about whether or not there are any woody orchids. Well, Bill checked. There aren’t any.<

Ep. 44 - Bryozoans & The Western New York Land Conservancy @ The College Lodge The Field Guides Download This episode is all about those gross jelly blobs that you might see in marinas (AKA Bryozoans!). Bill and Steve are joined by Jajean Rose-Burney, Deputy Executive Director of the Western New York Land Conservancy. Jajean guides Bill and Steve around The College Lodge Forest in Chautauqua County, NY, a wildlife-rich property that the Land Conservancy is seeking to preserve. Episode NotesListener Kathleen wrote to us asking us about Jajean's comment that the College Lodge property sits on the Continental Divide. Most people, I think it's safe to say, upon hearing the term "continental divide" would think of the divide that runs through the Rocky Mountains - technically known as the “Great Continental Divide”. But North America has six continental divides (see this link), and the divide that runs through the College Lodge property would be the St. Lawrence Continental Divide. Thank you to Kathleen for pointing out this potential point of confusion that we should have clarified!Steve mentioned that bryozoans sometimes compete with “turnicates”, but he meant to say “tunicates”. These are aquatic invertebrate animals.

Have you ever dreamed of ditching your day job and pursuing a career in the woods? Maybe working with wolves in the desert southwest or conducting plant surveys in the wilds of Alaska? Well, Matt Gaffney did it! Leaving behind a job in digital marketing, he went back to school to get his degree in environmental studies and went on to work a series of seasonal positions with the National Forest Service. Bill caught up with him in August of 2019 in the Monongahela National Forest in West Virginia. Join them on a hike on Spruce Knob (the highest point in WV) as Matt shares his adventures and advice on pursuing a career in the wild!

This month, Steve and Bill present part 2 of their episode on coyotes, focusing on the questions, “How big of a threat to livestock are coyotes?” and, “Is the coyote in the east a new species?”
