Species Description
The Brown-headed Cowbird (Molothrus ater) is a common bird found in North America. The males are black with brown heads while the females are a lighter brown to almost grey with stripes on their breast. The head and beak are finch shaped; they eat mainly insects and seeds. The Brown-headed Cowbird is a brood parasite meaning that it lays its eggs in the nests of other bird species, letting the deceived birds bear the burden of raising the young. Brown-headed Cowbird eggs have been found in over 220 different host species nests. If the host parents remove the parasitic egg the Brown-headed cowbird may attack and destroy the nest.
