Does water on a hen make it more susceptible to predation? In this episode, we comb through the literature on olfactory camouflage, dissecting studies assessing correlations between nest survival, weather, and environmental conditions, and divulging into the complicated web of ecology dynamics. Strap on your science boots for this one, it’s gonna be dense…

Join Timber University and special guest John Gruchy, a Wildlife Biologist with the Mississippi Department of Wildlife, Fisheries and Parks. John is the Coordinator of the Private Lands Program, including the Deer Management Assistance Program (DMAP). John discusses the finer points of managing the forest with prescribed fire and gives some insights for where landowners can go to gain the needed skills to set burns with confidence.

Finding an imperiled species on his ranch scared the daylights out of Russell Davis. What he and his neighbors did next may have saved their town.  
Today on Working Wild U, join us as we return to the high plains of eastern Colorado to learn how a small ranching community transformed a migratory bird’s imperiled status from threat to opportunity.

Brent Rogers, wild turkey historian and collector extraordinaire, joins us to break down wild turkey history through the eyes of early naturalists and literature. Learn how the culture and conservation concerns surrounding the wild turkey developed over time since the 17th century, what impacted transitions in knowledge and observation of wild turkey management, how restocking efforts have shifted throughout the decades, historical hunting practices, and more!

Often, the term “clearcut” is viewed as a 4-lettered word when it comes to forest or wildlife management. But, can clearcuts provide vital resources for songbirds – including those species typically associated with mature closed canopy forests? Join us for our conversation with Dr. Patrick Ruhl as we explore his research into songbird use of clearcuts in Indiana.
