[Birdtalk] Brood Parasitism

[Tim Avery]

This past weekend I stumbled upon my first in person encounter of wild bird
brood parasitism.  I was out just to take pictures when I happened upon the
overgrown intruder, a Brown-headed Cowbird, being fed by the tiny, taken
advantage of, Yellow Warbler.  I had seen pictures before, but in person
watching the little warbler feed a bird 3 times its size, it was incredible. 
To think that that the warbler doesn't realize that the bird it is feeding isnt
one of its own is incredible.  Talk about an ugly baby:
