Brown-headed Cowbird

Brown-headed cowbirds do not raise their own young, instead laying their eggs in the nests of other bird species. As a result, young cowbirds are not exposed to species-typical visual and auditory information like other birds. Despite this, cowbirds are able to develop species-typical singing, social, and breeding behaviors. A 2017 study demonstrated that cowbird brains are wired to respond to the vocalizations of other cowbirds, allowing young to find and join flocks of their own species.
