American Redstart



Scientific name: Setophaga ruticilla

Like most songbirds, American Redstarts stake out and defend territories during the breeding season. But winter territories are also defended vigorously by individual redstarts, although winter territories of female American Redstarts sometimes overlap with those of their neighbors. Redstarts also tend to return to the same winter territories year after year.

Brown-headed Cowbirds, which lay their eggs in the nests of other birds, often try to parasitize American Redstart nests. Redstarts are known to respond aggressively to a cowbird near their nest, or even abandon a nest containing cowbird eggs, though occasionally they will accept cowbird eggs and raise cowbird young.
