Introduction
The African Pygmy Goose, Nettapus auritus, is a very small African waterfowl species in the duck family Anatidae. Despite its common name, it is not a true goose. It is one of the perching ducks, a group named for its ability to perch on branches and other structures near water. The species is associated mainly with warm, shallow freshwater wetlands containing abundant floating vegetation, especially water lilies.
Physical Description
The African Pygmy Goose is about 27–30 cm long and weighs approximately 250–300 g. It has a compact body, short neck, rounded head and short, broad bill. Its small size, upright posture and colourful plumage make it distinctive among African waterfowl.
Adult males have a dark, glossy green crown and upperparts, a white face, chestnut flanks and pale underparts. The bill is yellow with a darker tip, and the head pattern includes a conspicuous green patch on each side. In flight, the dark wings show a prominent white wing panel or speculum.
Females are less brightly marked. They have a greyer, more mottled face, duller upperparts and a less vividly coloured bill. Juveniles resemble females but are generally more subdued in colour and pattern. Both sexes may perch on low branches, partly submerged trees and other structures close to the water.
Range and Habitat
The species has a broad but locally patchy distribution across sub-Saharan Africa, from parts of West Africa through Central and East Africa to southern Africa, and also occurs in Madagascar. It is recorded in countries including Senegal, Nigeria, Ethiopia, Kenya, Zambia, Botswana and South Africa, although its distribution is uneven and strongly dependent on suitable wetlands.
African Pygmy Geese favour shallow, still or slow-moving freshwater habitats with dense floating vegetation. Typical sites include swamps, marshes, floodplains, inland deltas, shallow lakes, oxbow lagoons, river pools and quiet bays. Water lilies, particularly Nymphaea species, are often an important feature of occupied habitat.
They are mainly sedentary, but local movements and nomadic dispersal can occur when rainfall, water levels or food availability change. They are rarely far from water and are poorly adapted to prolonged movement on land. Some coastal lagoons and estuarine wetlands may also be used, especially where freshwater vegetation is available.
Behaviour and Diet
African Pygmy Geese are usually seen in pairs, family groups or small flocks. Larger gatherings may form outside the breeding season where food and suitable water are concentrated. They are generally alert and can be difficult to approach, often remaining motionless among floating plants before flying rapidly across the water when disturbed.
The diet is mainly plant-based. Water-lily seeds, seed pods, flowers and other vegetative parts of aquatic plants are important foods, supplemented by seeds from other wetland plants. Aquatic insects, larvae and other small invertebrates may also be taken. The birds feed by picking food from the surface, dabbling among floating vegetation and occasionally diving or submerging the head and foreparts.
Their flight is fast and direct, with rapid wingbeats. They usually fly low over the water and seldom travel far when flushed. Pairs may maintain strong bonds, and breeding activity is generally associated with the rainy season, although timing varies across the species’ wide range.
The species is a cavity-nesting duck. Nests are most often placed in natural tree hollows or old cavities made by other birds, but suitable holes in termite mounds, cliffs, thatched structures or other sites have also been reported. The female typically lays 6–12 eggs and incubates them alone for about 23–24 days. The ducklings are precocial and leave the nest soon after hatching, sometimes making a substantial leap from an elevated cavity to reach the ground or water.
Identification Tips
- Look for a very small duck on quiet freshwater, usually among water lilies or other floating plants.
- The male has a glossy green crown and upperparts, a white face, chestnut flanks, pale underparts and a yellow, dark-tipped bill.
- The female is greyer and more mottled, with a less sharply patterned face and duller bill.
- A conspicuous white wing panel is visible when the bird flies.
- The species often rests or perches on low, partly submerged branches, a useful clue when it is not swimming.
- Its tiny size, rounded body and preference for lily-covered water help separate it from larger African ducks such as the Yellow-billed Duck and Hottentot Teal.
Conservation Status
The African Pygmy Goose is currently assessed as Least Concern on the IUCN Red List. Its extensive range and continued occurrence across many wetland systems mean that it is not presently considered globally threatened, although reliable population estimates and detailed trend information are limited.
Local populations may be affected by the loss and degradation of freshwater wetlands, drainage, agricultural conversion, altered water regimes, pollution, disturbance and changes to aquatic plant communities. The species benefits from the protection and appropriate management of wetlands, including the maintenance of natural flooding patterns, water quality, nesting trees and dense aquatic vegetation.
Frequently Asked Questions
Is the African Pygmy Goose a true goose?
No. Despite its common name, it is a small duck in the family Anatidae. It belongs to the genus Nettapus and is commonly grouped with the perching ducks.
Where does the African Pygmy Goose live?
It occurs across much of sub-Saharan Africa and in Madagascar. It favours shallow freshwater wetlands, including swamps, floodplains, inland deltas, lakes, oxbow lagoons and slow-flowing rivers with abundant floating vegetation.
What does the African Pygmy Goose eat?
Its diet consists mainly of water-lily seeds and other aquatic plant material. It may also eat seeds from wetland grasses, aquatic insects, insect larvae and other small invertebrates.
Does the African Pygmy Goose nest in trees?
Yes. It commonly nests in natural tree cavities or old holes made by other birds. Other reported nesting sites include termite mounds, cliff holes and cavities in human structures near suitable wetlands.
How many eggs does it lay?
A typical clutch contains 6–12 eggs. The female normally incubates the eggs alone for approximately 23–24 days, after which the precocial ducklings leave the nest and are led to water.
Is the African Pygmy Goose endangered?
It is currently classified as Least Concern on the IUCN Red List. Nevertheless, local populations depend on healthy freshwater wetlands and may be affected by habitat loss, pollution, disturbance and changes in water levels or aquatic vegetation.
