Essential Kelp Goose Information
Kelp geese are common in Patagonia, Tierra del Fuego, and the Falkland Islands, with a slightly larger subspecies found on the latter. These birds are highly specialized feeders, consuming only seaweed, and are known to travel long distances along the South American coast to find it. However, the Falklands population remains resident all year round.
Physical Characteristics
Male and female kelp geese look so different they are often mistaken for separate species. The male is strikingly white with yellow feet and a black beak, standing out against the rocky shoreline, while the female is a dark brown with grey lines across her breast and also has yellow feet. The female’s coloring provides excellent camouflage among the vegetation, particularly the long grasses they prefer for nesting.
Habitat and Nesting
Kelp geese favor coastal areas with long grasses like tussock, where females lay their eggs hidden among the vegetation. Typically, they lay 4 to 7 eggs in October or November. During this period, the male takes on the role of guarding the female as she incubates the eggs and protects the young chicks once they hatch.
Population and Distribution
The species, also known as Caranca in Spanish, has an estimated world population of around 30,000 individuals. Kelp geese are a common sight in the Falklands and can also be spotted in Ushuaia, where they are a highlight for many visitors.
Interesting Facts
- Color Differences: Males are pure white, while females are dark brown with grey lines, leading to frequent confusion over whether they are the same species.
- Specialized Diet: Kelp geese feed exclusively on seaweed, traveling long distances along the coast when necessary.
- Protective Males: The males play a key role in guarding the nest and chicks during the breeding season.
