Andean Duck Oxyura ferruginea

Sections

Andean Duck is the South American counterpart to Ruddy Duck (Oxyura jamaicensis) of North America. Currently Andean and Ruddy ducks are completely allopatric, but the northernmost populations of Andean Duck, in the Central and Eastern Andes of Colombia, are somewhat intermediate between the two species, suggesting introgression between them at some time in the past. Andean Duck is larger than Ruddy Duck; male Andean has an entirely black head, lacking the bold white cheek patch of Ruddy, and female Andean is much darker than female Ruddy. The biology of Andean Duck is very poorly known, although it probably is generally similar to that of Ruddy Duck.
