The bronzed cowbird (Molothrus aeneus) is a small passerine bird belonging to the family Icteridae. It is native to the Americas, primarily found in the southern United States, Mexico, and parts of Central America.

Description

The bronzed cowbird is a medium-sized bird, measuring approximately 20 cm (8 in) in length. The male has a distinctive glossy, bronzed plumage, while the female is generally duller with brownish tones. Both sexes have red eyes, which are particularly noticeable in the males.

Habitat

Bronzed cowbirds inhabit a variety of environments, including open woodlands, agricultural areas, and suburban regions. They are often found near water sources and are known to adapt well to human-altered landscapes.

Behavior

Feeding

Bronzed cowbirds primarily feed on seeds and insects. They forage on the ground, often in flocks, and are known to follow livestock to feed on insects stirred up by the animals.

Breeding

Bronzed cowbirds are brood parasites, meaning they lay their eggs in the nests of other bird species. The host birds then raise the cowbird chicks, often at the expense of their own offspring. This parasitic behavior can have significant impacts on the populations of the host species.

Distribution

The bronzed cowbird's range extends from the southern United States, through Mexico, and into Central America. They are year-round residents in much of their range but may exhibit some local movements in response to food availability and breeding opportunities.

Conservation Status

The bronzed cowbird is currently listed as Least Concern by the International Union for Conservation of Nature (IUCN). Despite their parasitic breeding habits, their population is stable, and they are not considered to be at significant risk.
