Ep. 34 - The Downy-Hairy Game

Ep. 34 - The Downy-Hairy Game

Did you ever wonder why Downy and Hairy Woodpeckers look so much alike? No? Neither did we, but it was because we always assumed they were simply closely related species. Maybe you did, too, but thanks to the wonders of DNA analysis, we now know that these two look-alikes are not even in the same genus. So, what gives?

Researchers recently looked into this stumper-of-a-problem, and, in this episode, Bill and Steve break down what might be the cause.

Oh, and Bill talks about how he might have Lyme disease.

Enjoy!

This episode was recorded at the Owens Falls Sanctuary in East Aurora, NY on January 6, 2019.

Ep. 32 - The Devil Crayfish (Feat. Dr. Wayne Gall)

Ep. 32 - The Devil Crayfish (Feat. Dr. Wayne Gall)

Have you ever heard of a burrowing crayfish? We hadn’t, until our much-smarter-than-us friend, Dr. Wayne Gall, shared the story of how he discovered one particular species living in western NY 30 years ago - Cambarus diogenes - the Devil Crayfish.

Wayne invited us to join him on a hunt for this species, to see if it was still present at Tifft Nature Preserve, three decades later.

Now, we invite you to come along with us, braving deep mud, crayfish pincers, and audio challenges (Tifft is lousy with the sound of trains, barges, and jets overhead). Along the way, Wayne proves himself a consummate storyteller, spinning the yarn of amazing coincidences that led to his connection with this species and publishing research about its presence in New York. We also give some visitors to the preserve a good scare.

A big thank you to Wayne for his time, expertise, and persistence. This episode may be shorter than usual, but we want you to know that Wayne spent hours with us at Tifft, his arms buried in the mud up to his shoulder, searching for our target species.

Bonus 08 - The Field Guides Live! (at the Allegany Nature Pilgrimage)

Bonus 08 - The Field Guides Live! (at the Allegany Nature Pilgrimage)

Imagine a gathering of nature-lovers where, for three days, you could attend hikes, talks, and other programs on dozens of natural history topics. Such a gathering takes place each year in Allegany State Park in southwestern NY. For over sixty years, The Allegany Nature Pilgrimage has taken place the weekend after Memorial Day, bringing like-minded individuals from across the country to share their knowledge of and passion for all things nature-related. The guys were invited to lead a hike at this year's Pilgrimage, and, in this special bonus episode, you can listen in on what it sounds like when a big group of people join Steve and Bill for a hike in the woods.

Our program was titled "The Skeptical Naturalist", and we focused on common natural history myths and some of the most interesting stories from past episodes. Enjoy, and we hope to see you at the Pilgrimage in the future!

Ep. 20 - Get the Buck Out!

Ep. 20 - Get the Buck Out!

So, how do you feel about deer? Over the past 100 years, populations of the White-tailed Deer (Odocoileus virginianus) have gone from scarce to ubiquitous. There’s a significant body of research pointing to the detrimental impacts of deer overbrowsing on our forests. Here at The Field Guides, we don’t like to exclude anyone, but we are interested in learning about deer exclosures – structures designed to keep these plentiful herbivores out of an area. Usually they are placed to allow for forest regeneration or to study the effects of deer exclusion; often, it’s done for both reasons. So what does the research show? Does excluding deer lead to healthier forests? This episode will shed some light on the answer. Listen to this rare, Steve-less episode as Bill is joined by Kristen Rosenburg, an environmental educator with the New York State Department of Environmental Conservation. They discuss deer exclosures, check some out at Kristen’s work site, and talk about what happens when researchers “Build That Wall!”. Special thanks to Kristen for sharing her time and expertise with us, as well as to the NYS DEC for allowing us to steal Kristen away for a morning.
