The cinnamon teal (Spatula cyanoptera) is a species of duck found in western North and South America. It is a small dabbling duck, with bright reddish plumage on the male and duller brown plumage on the female. It lives in marshes and ponds, and feeds mostly on plants. Description The adult male has a cinnamon-red head and body with a brown back, a red eye and a dark bill. The adult female has a mottled brown body, a pale brown head, brown eyes and a grey bill and is very similar in appearance to a female blue-winged teal; however, its overall color is richer, the lores, eye line, and eye ring are less distinct. Its bill is longer and more spatulate. Male juvenile resembles a female cinnamon or blue-winged teal but their eyes are red. They are long, have a wingspan, and weigh . They have 2 adult molts per year and a third molt in their first year. Distribution Their breeding habitat is marshes and ponds in western United States and extreme southwestern Canada, and are rare visitors to the east coast of the United States. Cinnamon teal generally select new mates each year. They are migratory and most winter in northern South America and the Caribbean, generally not migrating as far as the blue-winged teal (Spatula discors). Some winter in California and southwestern Arizona. Two subspecies of cinnamon teal reside within the Andes of South America. The smaller-sized S. c. cyanoptera is widespread within low elevations (<1,000m) such as the coast of Peru and southern Argentina, whereas the larger-sized subspecies S. c. orinomus occupies elevations of 3,500–4,600 meters in the central Andes. Behavior These birds feed by dabbling. They mainly eat plants; their diet may include molluscs and aquatic insects. Taxonomy The cinnamon teal is known to interbreed with the blue-winged teal, which is a very close relative. Five subspecies are recognised: Spatula cyanoptera septentrionalium (Oberholser, 1906) northern cinnamon teal breeds from British Columbia to northwestern New Mexico, and winters in northwestern South America. Spatula cyanoptera tropica (Snyder & Lumsden, 1951) tropical cinnamon teal occurs in the Cauca Valley and the Magdalena Valley in Colombia. Spatula cyanoptera borreroi (Snyder & Lumsden, 1951) Borrero's cinnamon teal (possibly extinct) occurs in the eastern Andes of Colombia, with records of apparently resident birds from northern Ecuador. It is named for the Colombian ornithologist José Ignacio Borrero. Spatula cyanoptera orinoma (Snyder &
