Yellow-rumped Warbler.
As I understand it, the two forms interbreed in a contact zone in British
Columbia. What about
the rampant interbreeding of Hermit and Townsend's Warblers recently

Here are the Proposals considered but not accepted by the committee as they
impact US birds

recognition of Eugenes viridiceps as a species distinct from the newly
