Black-throated Blue warbler

This is consistent with a first spring male (born last year) in view of the greenish edged primaries and secondaries (flight feathers seen to the left of the white handkerchief).

 

My shutter speed was a bit slower for a singing shot then I would like. Should ideally be at least 1/500, but the tripod saved the image... albeit slightly soft.
