Purple Grakle, or Common Crow Blackbird

Throughout the east and midwest, this big blackbird is a very familiar species on suburban lawns, striding about with deliberate steps as it searches for insects. Common Grackles often nest in small colonies, and several males may perch in adjacent treetops to sing their creaking, grating songs. Big flocks are often seen flying overhead in the evening, heading for major communal roosts, especially from late summer through winter.
