With a gleaming cinnamon head setting off a body marked in black and business gray, adult male Redheads light up the open water of lakes and coastlines. These sociable ducks molt, migrate, and winter in sometimes-huge flocks, particularly along the Gulf Coast, where winter numbers can reach the thousands. Summers find them nesting in reedy ponds of the Great Plains and West. Female and young Redheads are uniform brown, with the same black-tipped, blue-gray bill as the male.
