I lurk on one of the geekiest birds lists out there. It's called something like Bird ID Frontiers and it's mostly the bigwigs of birding debating gulls and various and sundry shorebirds. Every time I begin to think that these guys grok birding on a level I will never come close to understanding and thinkg about unsubscribing, a really cool post comes through. Today it was about a newly discovered and well documented warbler hybrid by Allen Chartier. He has posted photos and sound files on his website. The bird was banded at Metro Beach Metropark in Michigan on May 14, 2005.
