Anas cyanoptera

The Cinnamon duck (Anas cyanoptera), also known as Cinnamon Teal, has five subspecies.

The duck usually congregates in small groups or pairs. During the spring migration, the number of colonies increases to as many as 20 individuals. Spring migration usually occurs in March and April. The cinnamon duck winters in the southwestern United States or in Mexico and South America. They breed and migrate in groups of about 20 individuals. They also mingle with other species of teal, teal, spoonbill, hock duck, red spoonbill, and the South American spotted green duck.

Female ducks consume more food than male ducks, feeding mainly on root-growing or aquatic arthropods in marshes and lake areas. They eat the flowers, leaves, fruits and roots of plants. They also eat invertebrates and arthropods.

The breeding season of the duck is in winter, and the nest is formed from plant stems into a half-moon shape. Each nest lays 4 to 16 eggs. Incubation time is 21 to 25 days. The young birds leave the nest for 49 days and are usually incubated alone by the female ducks. After hatching, they are still cared for by the female ducks, and the ducklings follow the female ducks for food. By the eighth week, the duckling's eyes had turned red. A year later, they reach sexual maturity and are able to reproduce.

Listed on the International Union for Conservation of Nature (IUCN) 2013 Red List of Threatened Species ver 3.1 - Not Threatened (LC).
