During this episode, Steve talks about EVERY SINGLE extant non-human animal that drinks xylem or phloem sap. Join the guys as they explore the paradox of phloem sap, the barriers to eating it, how squirrels tap maple trees, hemipterans (true bugs), yellow-bellied sapsuckers, and much, much more. This episode stands alone, but we highly recommend listening to episode 17, "The Sappiest Podcast Ever..." either before or after this one. Either way, we hope you enjoy the episode!
During this episode, Bill and Steve talk about nature's junk food - sap! Join the guys as they cover how sap moves through Maple trees, as well as how climate change will affect Maples and the sap collecting season. They also interview two volunteers at the Beaver Meadow Audubon Center about turning Maple sap into syrup, cream, and sugar. Enjoy the episode!
Our 2nd bonus episode has arrived! This episode, Steve is joined by Matt from ‘In Defense of Plants’ & Sara from ‘Midwest Explorer’ for a hike at Hunter’s Creek Park. They talk about tree bark, bird poop, and American Sycamore Trees. Steve also ventures into Buffalo, NY to see the oldest American Sycamore in the world… allegedly (but probably not). Enjoy!
This episode, Bill and Steve discuss whether or not we should be feeding birds. Do filled feeders stop birds from migrating? Do they help birds survive the winter? Do they contribute to spreading disease throughout bird populations? All this and more - enjoy!
For this bonus episode, Bill, Steve, Chris, and Dave participate in the Christmas Bird Count. They count birds, talk about the history and findings of the count, and tell their own birding stories. Enjoy!
Winter is often perceived as a time of dormancy and inactivity, but underneath the snow, in the subnivean zone, a complex and fascinating world of plant and animal interactions exists. Weasels hunt through snow-roofed tunnels, herbivores graze on grasses, bark, and seeds, and occasionally the taloned feet of an owl punch through the roof, searching for a meal. In this episode, Steve and Bill pull back the snowy curtain, sharing recent research into what’s happening in the subnivean zone and the impacts of climate change on this intriguing and unseen winter world. This episode was recorded in the Shale Creek section of Chestnut Ridge Park, located in Orchard Park, NY.
This week Steve leads the discussion on "ice spikes." This is a rare winter phenomenon that Bill and Steve stumbled across at Stiglmeier Park (Cheektowaga, NY) during January, 2016. Join the guys as they run through two (presumably) incorrect hypotheses on how ice spikes form, and one well-documented method for their formation within freezers. We also explore the conditions that increase the chance of ice spikes forming in natural areas. While the episode mainly focuses on the "spike" form, "vase," "candle," and "tower" forms are also possible.
What the flock is up with murmurations? And what's the difference between a swarm, a herd, a school, and a flock? In this first of a two-part episode, Bill and Steve explore the world of collective behavior, and take a specific look at murmurations of the European Starling (Sturnus vulgaris). This species gathers in large flocks (sometimes numbering into the tens of thousands!) that dive and swoop across the sky, creating beautiful, shifting forms that delight, amaze, and mystify. Researchers from numerous fields study these formations, and this month, the Field Guides share the latest research into this stunning natural phenomenon.
This month's episode features Pokeweed (Phytolacca americana). This is a fascinating plant with some surprising tie-ins with American history. Join Steve and Bill as they tell you about pokeweed's uncommon red pigment, its use in phytoremediation, and the various ways in which it demonstrates toxicity. Enjoy!
Have you ever heard of a Fool's Hen? It’s just one of the many nicknames of the Spruce Grouse (Falcipennis canadensis), a bird of extremes and paradoxical behaviors. It often allows people to come within just a few feet before taking flight (hence the “fool” part of its nickname), but it can also be notoriously difficult to find. In addition, this species is adapted to survive on food that few other animals eat. Join Steve and Bill (and their friend, Rich) as they head into the wilds of Ontario Canada to search for this elusive critter, share the fascinating stories of its natural history, and shed light on some recent Spruce Grouse research. This episode was recorded in March of 2016 in Algonquin Provincial Park, Ontario, Canada.
Exploding seed pods?!? Flowers in the winter?! Many species have evolved unusual strategies for reproduction, and this month’s target species is no exception. Witch Hazel (Hamemelis virginiana) is a small tree of the eastern forest understory that is easy to miss. It’s small and unassuming, but closer inspection reveals an array of fascinating adaptations that make it unique among our woodland species. Join Steve and Bill as they hunt for this wonder of the woods and share what they learned about it.
Have you ever heard of Valcour Island? Bill and Steve heard tantalizing rumors about it and journeyed to Lake Champlain to check it out. Champlain borders both New York and Vermont, and one of its largest islands is Valcour, home to a number of rare plants and the largest Great Blue Heron rookery in New York. The Field Guides camped out on this special place, exploring, botanizing, and demonstrating why they are the slowest hikers on the planet. Come along for the ride and experience the fascinating finds Bill and Steve discovered.
OK, Field Guides listeners - *Bill and Steve crack their knuckles* - this one's a touchy subject for some people, but it's an important one. Just how much DO our food choices impact the environment? There's ample rhetoric on both sides, but what does the research say? In this episode, Steve and Bill tell you what they discovered, all while trying their best not to get too preachy. (As an added bonus, they fill you in on what they thought of Scott Pilgrim vs. the World). This episode was recorded in the Letchworth Woods area of the University at Buffalo's north campus in western NY.
It may be "the most numerous forest vertebrate" in many areas of the northeast, but the Redback Salamander (Plethodon cinereus) is rarely seen unless you're looking for it. In this episode, Steve and Bill hunt for some Redbacks while sharing recent research on its ecology. Give a listen, and hear the fascinating life history of this abundant but seldom seen forest denizen - and find out why Steve and Bill haven't posted an episode in three months!
