Castorology (BEAVERS) with Rob Rich

Orange teeth! Vanilla butts! Architecture with twigs! Olde-timey joke books? Field naturalist, conservationist, wildlife tracker and “beaver believer” Rob Rich works with the National Wildlife Federation’s coordination of the Montana Beaver Working Group and answers all of our Castorological questions about: baby beavers, tooth tools, lodges, dams, the sound of water, the slap of a tail, who eats beaver and why, beavers in peril, in folklore, in smut books, in your neighborhood and in your dreams forever. Also: yes we discuss slang.
