Brown-headed Cowbird

    Related Articles


    Few birds are as generally disapproved of as the Brown-headed Cowbird ( Molothrus ater), which lays its eggs in the nests of other birds, particularly flycatchers, sparrows, vireos, and warblers. A newly hatched cowbird quickly grows larger than the rightful nestlings and devours most of the food; it may even push the host’s eggs or young out of the nest. The foster parents feed the huge intruder until it can fly.
