Brown-headed Cowbirds These are either female or juvenile Males have Brown Heads... Fact: The Brown-headed Cowbird is a stocky blackbird with a fascinating approach to raising its young. Females forgo building nests and instead put all their energy into producing eggs, sometimes more than three dozen a summer. These they lay in the nests of other birds, abandoning their young to foster parents, usually at the expense of at least some of the host’s own chicks. -allaboutbirds.org | Critter Cam
