The male Red-winged Blackbird can be told from the male Tricolored Blackbird by its yellowish, not white, border to the red shoulder patch. Females are quite similar but Tricoloreds typically have darker bellies. Other species of blackbirds lack the red shoulder patch of the male and the streaked underparts of the female.
