Red-winged blackbird

The name is taken from the male bird’s distinctive red shoulder patches, or “epaulets”, which are visible when the bird is flying or displaying. At rest, the male shows a paler yellow wingbar against a black background. The female is an inconspicuous shade of brown and considerably smaller than than the male. The adult birds are from 7 to 9.5 inches long, and have distinctive sharp bills.

Red-winged blackbirds are one of the most abundant birds in North America. The males are very territorial during breeding season, defending their territory with song and chasing, as seen here.
