Brewer's blackbird (Euphagus cyanocephalus) is a medium-sized New World blackbird. It is named after the ornithologist Thomas Mayo Brewer. Adult males have black plumage with an iridescent purple head and neck and glossy bluish-green highlights on the rest of the body. The feet and legs are black and the eye is bright yellow. The female is brownish-grey with slight hints of the male's iridescence. The female's eyes are dark brown, while the male's is bright yellow. Overall, they resemble the eastern member of the same genus, the rusty blackbird; Brewer's blackbird, however, has a shorter bill and the male's head is iridescent purple. This bird is often mistaken for the common grackle but has a shorter tail. The call is a sharp check which is also distinguishable. This bird is in a different family from the Eurasian blackbird.
Their breeding habitat is open and semi-open areas, often near water, across central and western North America. They are also very common in parking lots or around schools, and easily acclimate to the presence of people. They can live in low elevation, as low as below sea level in Southern California, and elevations as high as 8... Wikipedia →
