The bronzed cowbird (Molothrus aeneus), once known as the red-eyed cowbird, is a small icterid.
They breed from the U.S. states of California, Arizona, New Mexico, Texas, and Louisiana south through Central America to Panama. They tend to be found in farmland, brush, and feedlots. Outside the breeding season, they are found in very open habitats, and roost in thick woods. These birds forage in open areas, often near cattle in pastures.
The male bronzed cowbird is 20 cm long, with green-bronze, gloss-black plumage. His eyes are red in breeding season and brown otherwise. The female is 18.5 cm long. She is a dull black with a brown underbelly, and has brown eyes. Young birds have coloring similar to the females, with the exception of grey feather fringes.
