Grayish baywing
The grayish baywing, formerly known as the bay-winged cowbird, is a species of bird in the family Icteridae. It is currently placed in the genus Agelaioides but has traditionally been placed in the genus Molothrus. It is found in the northern half of Argentina, Bolivia, Uruguay, Paraguay and southern and central Brazil, The isolated population in north-eastern Brazil is usually now considered a separate species, the pale cowbird or pale baywing. The greyish baywing has been recorded as a vagrant in Chile.It has a total length of approximately 18 cm. 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.
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 bay-winged cowbird, and while adult screaming cowbirds are overall blackish, juvenile screaming cowbirds closely resemble bay-winged cowbirds.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.
