Ржавчатый трупиал Euphagus carolinus

Rusty edges to feathers and pale eyebrow in winter contrast with blackish feather bases. Breeding males are glossy black. Shorter tail than Common Grackle. Thinner bill than Red-winged Blackbird. Found in wooded swamps. Often in flocks; frequently mixes with Red-winged Blackbirds and Common Grackle in winter. Look for flocks perched at tops of trees bordering marshes and listen for their calls to help pick them out from large flocks of blackbirds.
