Black-throated Blue Warbler
Male Black-throated Blue Warblers are one of the more conspicusous wood warblers due to their striking plummage. Female exhibit some sexual dimorphism as they are a drab olive with lighter underparts. They prefer dense forests of deciduous trees as they forage for insects, gleaning from them from the undersides of leaves. I was lucky enough to see a male(aside from the male that I prepared as a specimen) come through my tiny Chicago back yard one spring. Now that I have a greater idea of the risks an urban area poses for migrating birds, I think back on that little guy and hope that he was able to make it north okay to breed.
