Brown-headed Cowbird

Posted by Scott (Allentown, United States) on 26 June 2009 in Animal & Insect and Portfolio.

I've posted a couple of photos of these in the past, but this is a much better shot. This bird is considered a parasite, in that it uses nests of other birds to lay its eggs, instead of building its own. This has a tendency to cause other species to be reduced in numbers, as the cowbird is often the largest and strongest bird in the nest.
