Red-winged Blackbird

Which runs faster, hot or cold?

Hot. Everyone can catch cold.

One California subspecies of the Red-winged Blackbird lacks the yellow borders to the red shoulders (epaulets) and has been dubbed the “bicolored blackbird.” Some scientists think this plumage difference may help Red-winged Blackbirds recognize each other where their range overlaps with the similar Tricolored Blackbird.
