This episode, we’re stepping back to the golden age of natural history podcasting by resurrecting the format of the classic show Wild Ideas: The Podcast. Joining us on the trail is one of the OG hosts: the man himself, Gordon Maupin. It’s a 3-way team-up where each of us brings a heavy-hitting seasonal mystery to the table. First, Steve unravels the rule-breaking world of the Ambystoma polyploid salamander complex, where unisexual lineages are mixing up DNA from different species and blurring the lines of what makes a species a species. Then, Gordon shrinks things down to look at the world of
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 th
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.
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 th
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
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. They're joined by 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.
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.
Episode 76 takes the guys back into 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?
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.
What exactly is a “naturalist”? Spend a little time with Sandy Geffner, and you’ll find out. Steve and Bill rarely go more than an episode or two without mentioning him—a naturalist who profoundly shaped both their lives. This month, they head into the woods to talk with Sandy about how a baseball-loving kid from Long Island became someone who’s inspired countless people to deepen their connection with the natural world.
It’s hard to believe, but we’re doing another episode on fish! This time around, Steve introduces us to the Sturgeon (family Acipenseridae), from their dinosaur-era origins to their caviar-fueled scandals (did you know Beluga caviar comes from Sturgeon? Bill didn’t either). So strap in as the guys touch on Sturgeon, for the very first time.
In this special bonus episode we're crossing over with The Spark Bird Podcast! (@sparkbirdproject) Bill joins one of the hosts of the Spark Bird Project podcast, Jenn Lodi-Smith, to go birding in Buffalo’s historic Forest Lawn Cemetery, sharing spark bird stories, conservation efforts for migration, and the joy of birding in community. You’ll also hear reflections from folks at the Feminist Bird Club of Buffalo (@fbc.buf) May the Spark Be with You outing, all recorded on-site at Forest Lawn Cemetery. This episode is a celebration of connection, accessibility, conservation, and the shared love
Bill and Steve return for the second part of their look into the Dawn Chrous, that early morning explosion of bird song that refuses to let you sleep in.

In this episode, Steve leads a discussion on the invasive Grass Carp. The guys go over the evolutionary history of grass carp and its relatives, its biology, its introduction to The Great Lakes region, why people are concerned, and anything interesting Steve found out about it. There are a lot more interesting fish topics that we can explore in the future, at least while Steve is researching fish. Enojy the episode!
he 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.
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 intervie
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 pu
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
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. Join the guys for a wide-ranging discussion on fishers, connectivity, and wildlife-human interaction.
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. Join the guys as they get caught in a sudden rainstorm and learn about this amazing plant.
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. 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.
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.
Bill meets 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.
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.
