Casey Clapp from Completely Arbortrary joins Tobin to chat with the man, the myth, the Sibley. David Allen, that is!

David is a world-renowned ornithologist and author of The Sibley Guide to Birds and many other birding books, but also the author of Casey and Tobin's favorite tree guide, the inimitable Sibley Guide to Trees. Tobin, Casey, and David cover the reasons for foliage intensity, inspirational figures from childhood, possible events for the Naturalist Olympics, and, of course, what to do if you have a toddler who loves to destroy every piece of green they see.
