Hi All, After I posted the link on VA-Birds about the unusual warbler I photographed a few days ago at http://www.pbase.com/mayhorn/warbler_june_09 I received an e-mail from Jeremiah Trimble in Massachusetts who had photographed a bird with the same markings as the one I had. Jeremiah is the Curatorial Associate (whatever that means) of Ornithology a the Museum of Comparative Zoology in Cambridge, MA. He believes the bird is a Lawrence's Backcross. Here is the link to his photos http://www.flickr.com/photos/jrtrimble/sets/72157619102563564/ Roger Mayhorn Compton Mt
