The Brown-headed Cowbird is a small bird native to North America, known for its distinctive brown head and black body. Adult males have a shiny black plumage with a rich brown head, while females are more subdued in color, featuring a streaked brown appearance. These birds are often found in open fields, pastures, and near human settlements. A unique behavior of the Brown-headed Cowbird is its practice of brood parasitism. Instead of building their own nests, they lay their eggs in the nests of other bird species, such as American Robin or Song Sparrow. This strategy allows them to save energy and increase their chances of survival.
