- Agelaioides badius
Light brown overall with rufous wings, heavy black conical bill, black legs and eyes, and black lores.
South America: found in Bolivia, Paraguay, Uruguay, Argentina and Brazil.
Especially older checklists have placed this species in the genus Molothrus, but it is now placed in genus Agelaioides.
Pale Baywing was formerly included in this species.
This is a polytypic species consisting of two subspecies:
- Highlands of central and southern Bolivia
Semi-open habitats, including scrub and light woodland.
It sometimes builds its own nest or uses those of other birds. It is a victim of brood parasitism by other cowbirds mainly the Screaming Cowbird Molothrus rufoaxillaris.
