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.
Tricolored Blackbirds are only found in Oregon and California. Other species
of blackbirds lack the red shoulder patch of the male and the streaked
underparts of the female.
