The Red Shoveler is a medium-sized duck of southern South America. Populations in the southern part of its range are short-distance migrants, while more northerly populations are residents. The bill is slightly longer than the head and spatulate, giving the species its common name. More often found in brackish waters than other dabbling ducks, the Red Shoveler is a denizen of large coastal lagoons, lakes, and estuaries. Like other dabbling ducks, it feeds from the surface of the water by head-dipping and upending, rarely making shallow dives in search of algae or plankton. The Red Shoveler is fairly common in the proper habitat, and sometimes gathers in huge groups of 10,000 individuals or more.
