Identification
Distribution
Widely considered extinct but it is thought by some to survive in very small numbers. No authenticated records since the early 1960s. Formerly bred in extreme north-west Canada and possibly Alaska.
In the 1800s, large numbers wintered in south-central South America, migrating via north-east North America and south on the Atlantic coast. Vagrants recorded in Greenland and northern Siberia, also on the Falklands.
In the Western Palearctic vagrants recorded in Ireland and Britain, all were in September-October but none have been seen since 1887. Even if the species is not extinct, the population is undoubtedly very low and so future transatlantic vagrancy is extremely unlikely.
Taxonomy
Habitat
Bred on Arctic tundra, otherwise on natural grassland or farmland.
Behaviour
Comments
Presenting possible hope to their continued suvival, unconfirmed reports have continued through to the present day, including on former migration routes and in their South American wintering grounds. Most of these records relate to single birds, though one oberver talks of flocks numbering 20 to 150.
