Bronzed CowbirdMolothrus aeneus
- ORDER: Passeriformes

A Central American bird, the Bronzed Cowbird makes its way to the United States only in the border states and Louisiana. Like other cowbirds, the female does not make a nest, but instead lays her eggs in the nests of other bird species.More ID Info

- Cool Facts
- Nest success for brood parasites (birds that lay eggs in the nests of other bird species) usually is best when only one parasite egg is laid in a given nest. Host nests frequently contain multiple Bronzed Cowbird eggs. Some female cowbirds peck the other cowbird eggs before laying their own eggs, effectively reducing the number of cowbird eggs in the nest.
- The maximum number of Bronzed Cowbird eggs found in one nest was 14 in an abandoned nest.
- The oldest recorded Bronzed Cowbird was a male, and at least 8 years old when he was found in Texas.
