Red-winged Blackbird Patch

#50 Red-winged Blackbird Red-winged Blackbirds are one of the most abundant birds in North America. The ringing call of the glossy-black males, who puff up and flare their red-and-yellow shoulder patches, is one of the continent’s harbingers of spring. They claim territory early, just about anywhere with standing water and vegetation, and the streaky-brown females soon follow.
