Euphagus

Euphagus is a small genus of American blackbirds. It contains two extant species: Brewer's blackbird, Euphagus cyanocephalus, and rusty blackbird E. carolinus. A prehistoric relative, Euphagus magnirostris, is known from Late Pleistocene fossils found in the famous tar seeps of Rancho La Brea, California. The living species are very similar medium-sized birds. Adult males have mainly black plumage and a bright yellow eye; females are dark gray-brown. Both are migratory, wintering in the southern United States and Mexico, although some Brewer's blackbirds are present all year in the western US.
