The red-mouted duck (Anas erythrorhyncha) is a highly social social species, with colonies reaching several thousand during the breeding season or at the end of the dry season, up to 500,000 in Lake Ngami, Botswana. Most of the activities are in the wild grass in the marsh area near the water. The male calls resemble the rhythm of a telephone, while the female calls are soft.
The duck mainly feeds on roots, grass seeds, leaves, grass fruits, rice, etc. in marshes and lake areas, and also eats invertebrates and arthropods.
The breeding season of the duck is after the dry season in southern Africa, usually between December and April, when it builds a bowl-shaped nest of plants and grasses in dense vegetation near water sources. The nest rises above the nearby waters and is hidden in the water grass. Each nest lays 4 to 12 eggs and incubates for 24 to 28 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.
Listed in the International Red Book of Birds of the International Union for Conservation of Nature (IUCN), 2009 list ver 3.1.
