Did you see the warbler chapter in the newly updated book by Kenn Kaufman, A Field Guide to Advanced Birding?

Yes, Amy (in Orlando): Kenn Kaufman’s update (from his original and now classic original A Field Guide to Advanced Birding) hosts an excellent chapter devoted to wood-warblers titled “Learning to Identify Warblers”

This insightful chapter is divided into subthemes such as “How To Look At Warblers,” “Learning The Groups of Warblers,” “What To Look For In Identifying Warblers,” and “Understanding What You Hear: Warbler Voices.”

Especially well done is Kaufmann’s explanation of warbler songs that he notes consists of two major song types in many warbler species.

He also expertly delineates the difficult autumn plumage ID challenge of the “Blackpoll Trio” consisting of Blackpoll Warbler, Bay-Breasted Warbler, and Pine Warbler.
