I filmed the male Blackburnian Warbler in the video below earlier today. I was conducting one of the first few surveys of the 2010 Stratford Great Meadows IBA Breeding Bird Survey. The entire area was loaded with migrant birds. Migration was heavy last night, and combined with incoming thunderstorms from the northwest, birds were pushed and dropped along much of the coast. In about six hours I had 17 warbler species and 95 species overall. You can hear the voice of this male as he repeatedly belts out his soft and high-pitched song.
