Usually seen walking around on the ground in grassy areas, this blackbird is common in city parks, agricultural fields, marshes and riparian areas. It breeds in small colonies, and the nest of each pair is made of grass and mud and placed in various places from the ground to branches of high trees. It is commonly parasitized by cowbirds. During the winter it usually associates with huge flocks of Red-winged Blackbirds. Insects and other arthropods make up much of the diet in the summer, but seeds are the main food in the winter.\r\n
The four-digit banding code is BRBL.
