The '''Brown-headed Cowbird''' (''Molothrus ater'') is a small [[icterid]].

Adults have a short [[finch]]-like bill and dark eyes. The adult male is mainly [[Iridescence|iridescent]] black with a brown head. The adult female is grey with a pale throat and fine streaking on the underparts.

Breeding in open or semi-open country across most of [[North America]], this [[bird]] is a [[brood parasite]]: it lays its [[Egg (biology)|egg]]s in the nests of other small [[passerine]]s (perching birds), particularly those that build cup-like nests, such as the [[Yellow Warbler]]. The young cowbird is fed by the host parents at the expense of their own young.

Brown-headed Cowbirds are permanent residents in the southern parts of their range; northern birds [[bird migration|migrate]] to the southern [[United States]] and [[Mexico]]. They often travel in flocks, sometimes mixed with [[Red-winged Blackbird]]s or [[European Starling]]s.

These birds forage on the ground, often following grazing animals such as [[horse]]s and [[cattle|cow]]s to catch [[insect]]s stirred up by the larger animals. They mainly eat [[seed]]s and insects.

At one time, the Brown-headed Cowbird followed the [[American Bison|bison]] herds across the [[prairie]]s. Their [[parasite|parasitic]] nesting behaviour complemented this [[nomad|nomadic]] lifestyle. Their numbers expanded with the clearing of forested areas and the introduction of new grazing animals by settlers across North America. Brown-headed Cowbirds are now commonly seen at suburban birdfeeders.

Brown-headed Cowbird females can lay 36 eggs in a season. Over 140 different species of birds are known to have raised young cowbirds. Host parents may sometimes notice the cowbird egg. Different species react in different ways. [[Gray Catbird]]s destroy the egg by pecking it. Some species may simply build a new layer over the bottom of the original nest. Brown-headed cowbird nestlings are sometimes expelled from the nest.
