In this special episode, we've asked two rock star ornithologists to answer a flock of listener questions about birds. Drew Lanham and Corina Newsome talk flying, feathers, eggs, poop and how we humans can help birds. Plus: we test their ears with the Mystery Sound and their obscure bird knowledge with a game called Real Birds or Just Words.

And many, many thanks to The Macaulay Library at the Cornell Lab of Ornithology for providing the bird sounds you hear in this episode.
