The green-headed duck, also known as the green-headed teal or Anas chlorotis, is a small, brightly colored duck native to South America. It is a member of the Anatidae family, which includes ducks, geese, and swans.
The green-headed duck is distinctive in appearance, with a bright green head and neck, a white breast and belly, and a brown back. It has a small, pointed bill and long, thin legs. The male and female are similar in appearance, with the male being slightly larger and having a more colorful head and neck.
Green-headed ducks are found in wetland areas, including marshes, swamps, and lagoons. They are found throughout much of South America, including Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, and Uruguay. They are migratory birds, and may move between different parts of their range depending on the season.
Green-headed ducks are omnivorous, feeding on a variety of plant and animal matter. They primarily eat seeds, grains, and aquatic plants, but also consume insects, snails, and small fish. They forage by dabbling at the water’s surface, using their bill to filter food from the water.
Green-headed ducks are social birds, and are often found in small flocks. They are known for their vocalizations, which include a variety of calls and whistles.
The green-headed duck is not considered to be endangered, although its population size is thought to be declining. Habitat loss and degradation, as well as hunting and poaching, are potential threats to the species.
Overall, the green-headed duck is a fascinating and colorful bird that is an important part of South America’s biodiversity.

Both the male and female participate in incubating the eggs and caring for the young.
