Charles and Jon talk to distinguished mammalogist Dr Roland Kays, head of the Biodiversity lab at the North Carolina Museum of Natural Sciences and a Professor at North Carolina State University. Roland has published on sloth sleep and incognito Olinguitos and written a North American mammal field guide - also an app - that many of you will have. Roland talks about his work describing the Olinguito, one of the most significant new mammal discoveries of the 21st Century (it was the first new carnivore for the Western Hemisphere in 35 years). He explains his love of both Fishers and Porcupines and the quest to capture footage of the former hunting the latter. And he explains, with great clarity, the secret recipe to Canis soupus!

Notes: Roland's Field Guide to the Mammals of North America is also available as an Apple and Android app (look for "Mammals of North America").

Roland's Wild Animals Podcast is now into Season 3, and he has a Youtube Channel with the same name. This is the Fisher vs Porcupine video he mentioned.
