Distribución y hábitat

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. 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 (&lt;1000m) such as the coast of Peru and southern Argentina, whereas the larger size subspecies S. c. orinomus occupies elevations of 3500–4600 meters in the central Andes.
