Description and behavior

It has a total length of approximately 18 cm (7 in). It is overall ashy-brown with contrasting black lores and rufous wings. The taxon fringillarius has more black in the face and is overall more rufescent (less ashy).

It is social and commonly seen in small groups. Unlike the "true" cowbirds in the genus Molothrus, this species is not a brood parasite. In contrast, the screaming cowbird is a brood parasite of the grayish baywing, and while adult screaming cowbirds are overall blackish, juvenile screaming cowbirds closely resemble grayish baywings.

Habitat and status

It is found in a wide range of semi-open habitats, including scrub and light woodland. It is generally fairly common, and consequently considered to be of least concern by BirdLife International and IUCN.

gollark: Not believing in Eric is an antiEric belief.
gollark: No, antiEric beliefs are antiEric heresy, simple.
