The sleek and secretive fisher, doesn’t fish or even like to swim. This beautiful mammal is a cousin of the weasel, otter and badger, living in old growth forests, having their kits in cavities of trees under lush forest canopies, moving quickly on forest floors and traveling miles via creek corridors. Though endangered in the Sierra Nevada mountains, experts use hidden cameras and tracking collars to understand their lives in order to help their populations. 

In this episode of Critter Chat, hosts Marney Blair and Susan Brandt speak with experts about the fisher, a rare mammal of the Sierras, about their behavior, threats and efforts to save them. Guests on the show are: Andria Townsend, wildlife biologist and carnivore specialist, Yosemite National Park; Professor Emeritus Roger Powell, author of The Fisher, Life history, ecology, and behavior, the definitive book about the fisher; and biologist and Poet Laureate of Sonoma County, Maya Khosla, who will share her observations and references, and read her poetry about a female fisher, who is about the size of a house cat. 

Teachers are encouraged to use Critter Chat in their classrooms. Concepts like “misnomer” and “fitness landscape” are discussed as well as an explanation of National Park vs National Forest are included in this episode featuring the fisher.
