Osprey on nest at Miller Ferry, AL

Brown-headed Cowbird - Adult Male - Cowbirds 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.
