Large Flock

Some on the birdbath, some on the ground I have never had a flock this large all at one time at the birdbath of brown-headed cowbirds.....Cowbirds lay eggs in a great variety of nests, including Red-winged....Common hosts include the Yellow Warbler, Song and Chipping sparrows, Red-eyed Vireo, Eastern and Spotted towhees, and Red-winged Blackbird.Blackbird nests....Over 140 host species of the Brown-headed Cowbird. Some birds notice the different egg and will remove it.
