Kelp goose description
Commonly found in pairs (3), the contrast between the bright white plumage of the adult male and the dark, striped plumage of the female kelp goose presents a striking image (2). The male is almost entirely white, with the exception of the bill, which is black, and the legs and feet, which are orange. The female has more elaborate colouration, with chocolate-brown upperparts, head and neck, while the belly is boldly striped blackish-brown and white. The rump, tail feathers and underwing are also white, with the exception of the black primary feathers visible at the wing tips. The female’s bill is pink, the legs are orange, and there is a thin white ring around the eye. While both male and female juveniles resemble the adult female, the male acquires white plumage on the head, neck and upperparts in the first winter, becoming almost completely white by the second. Along with the contrasting appearances, both sexes produce different vocalisations, with the male kelp goose giving a repeated whistle, and the female, a harsh growl (2).
There are two subspecies of kelp goose, the lesser kelp goose, Chloephaga hybrida hybrida, and the greater kelp goose, Chloephaga hybrida malvinarum, which can be distinguished by size and location (2)
- Length: 52 – 65 cm (2)
Kelp goose biology
Egg-laying takes place between late October and early November, with the female kelp goose laying a clutch of four to seven eggs in a nest made of grass and lined with breast feathers, concealed behind the beach amongst tall grass or shrubs (2) (4). During the month-long incubation period, the male stands guard over the female. Once hatched, the chicks are led from the nest, and must find their own food while remaining under the protection of the parent birds. Fledging takes place in February and the young birds become fully independent, but do not reach sexual maturity until two years old (4)Top
Kelp goose range
The breeding range of the lesser kelp goose, Chloephaga hybrida hybrida, extends from southern Chile, through Tierra del Fuego to the extreme south of Argentina, with populations at the most southerly regions migrating northwards slightly beyond the northern limits of the breeding range in the winter. The greater kelp goose, Chloephaga hybrida malvinarum, is restricted to the Falkland Islands, where it remains resident throughout the year (2).Top

Kelp goose conservation
With a large and healthy population, specific conservation action is not required for the kelp goose (1). Nevertheless, conservation organisations within this species’ range are working to preserve biodiversity, thereby ensuring that the kelp goose remains abundant (5) (6).Top
