Okay, but what's the deal with nests?

E34. Not all birds build one, but for the ones that do, a nest has a single job and a shockingly wide range of ways to get it done. Dr. Vanya Rohwer, Curator of Birds and Mammals at the Cornell University Museum of Vertebrates, joins Scott to walk the far end of that spectrum, from nests made entirely of spit to a colony structure heavy enough to snap the tree it sits in. In this episode you'll hear about: The complete and comical inventory of one hamerkop nest, read aloud, contents included What a bird does when you hand it a nest somebody else already built Why a shed snakeskin in a tree cavity is a calculated decoration New episodes every Thursday.
