Black-tailed Godwit - Distribution and Habitat

Distribution and Habitat

Black-tailed Godwits have a discontinuous breeding range stretching from Iceland to the far east of Russia. Their breeding habitat is river valley fens, floods at the edges of large lakes, damp steppes, raised bogs and moorlands. An important proportion of the European population now uses secondary habitats: lowland wet grasslands, coastal grazing marshes, pastures, wet areas near fishponds or sewage works, and saline lagoons. Breeding can also take place in sugar beet, potato and rye fields in the Netherlands and Germany.

In spring, Black-tailed Godwits feed largely in grasslands, moving to muddy estuaries after breeding and for winter. On African wintering grounds, swamps, floods and irrigated paddy fields can attract flocks of birds. In India, inland pools, lakes and marshes are used, and occasionally brackish lakes, tidal creeks and estuaries.

Godwits from the Icelandic population winter mainly in the United Kingdom, Ireland, France and the Netherlands, though some fly on to Spain, Portugal and perhaps Morocco. Birds of the limosa subspecies from western Europe fly south to Morocco and then on to Senegal and Guinea-Bissau. Birds from the eastern European populations migrate to Tunisia and Algeria, then on to Mali or Chad. Young birds from the European populations stay on in Africa after their first winter and return to Europe at two years old. Asian Black-tailed Godwits winter in Australia, Taiwan, the Philippines, Indonesia, and Papua New Guinea.

Black-tailed Godwits are much more likely to be found on inland wetlands than the more coastal Bar-tailed Godwit. They migrate in flocks to western Europe, Africa, south Asia and Australia. Interestingly, although this species occurs in Ireland and Great Britain all year-round, they are not the same birds. The breeding birds depart in autumn, but are replaced in winter by the larger Icelandic race. These birds occasionally appear in the Aleutian Islands and, rarely, on the Atlantic coast of North America.

There is an estimated global population of between 634,000 to 805,000 birds and estimated range of 7,180,000 square kilometres. In 2006 BirdLife International classified this species as Near Threatened due to a decline in numbers of around 25% in the previous 15 years. It is also among the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
