Animal Characteristics

Identification:A leaf-shaped comb sits on the male knob-nosed goose's bill. The male also has a dark back glossed with purple, bronze, and green. His head is a creamy white color, spotted black, and the hind neck has a hint of orange. The female duck is less glossy, and she has no comb or spots on her head.
Habitat:Wooded wetlands
Diet:Omnivore: aquatic vegetation, grass seeds, invertebrates, small fish
Reproduction:African populations breed during the rainy season. Knob-nosed geese can be monogamous or polygamous breeders. Nests are built in tree cavities and may be shared by the females in a harem. There are usually 6-11 eggs in a nest, but there can be as many as 50. The dominant female will incubate the eggs for one month.
Knob-nosed geese gather in flocks outside of the rainy season.
Behavior:Knob-nosed geese may migrate during the dry season. They will often perch in trees.
Status:No special status
