Range Description

Tryngites subruficollis breeds sporadically along arctic coasts from central Alaska, USA to Devon Island, Canada, with a relict population on Wrangel Island and west Chukotka, Russia. Also reported from St Pierre and Miquelon (to France) as a non-breeder. Birds winter in eastern South America including Argentina, Uruguay, Paraguay and Bolivia after passing through the Greater and Lesser Antilles or around the Gulf coast of Central America. Originally numbering in the hundreds of thousands to millions (1890s-1900s), the species was brought to near extinction in the early 1920s by hunting. It has not recovered, with the current population estimated at 16,000-84,000 individuals based on various estimates from birds passing through the Rainwater Basin in Nebraska and the Gulf coastal plain in Louisiana and Texas5. It is difficult to monitor, as it is not faithful to breeding sites (and possibly not to wintering sites), but data from North American migration sites suggests that declines are continuing.

Ecology

Ecology (Behaviour)

It is a lekking species.

Birdlife International

Habitat

It breeds in the high Arctic on well drained tundra with tussocks and scant vegetation. It is generally not near the sea and avoids marshes. It appears to depend heavily upon intensive grazing by livestock in its wintering grounds to creat short grassland4, but also uses flooded Pampas grasslands. During migration it is found on many short grass habitats.

International Status

IUCN Red List Category

NT

Justification

This species underwent rapid historical declines. Its moderately small remaining population continues to decline and as a result it is considered Near-Threatened.
<Population Justification> Morrison et al. (in press).
<Trend justification> A moderate and on-going decline is suspected based on surveys at staging posts. This is thought to be driven by habitat loss and conversion, but contaminants may also have an impact.

Management

Threat

It was severely overhunted in the early part of the 1900s reportedly declining to near extinction from a population which may have number in the millions. Immediate threats are the matter of some conjecture. The breeding grounds may be affected by habitat loss and degradation and environmental contaminants3. Previously, ongoing declines were attributed to widespread and continuing destruction of grasslands in the wintering range1,2, but there seems little evidence to support this, although environmental contaminants may be playing a part there3. Exposure on migration ot toxic chemicals and pollutants may pose a threat and is being investigated further6.

Current Conservation

CMS Appendix I and II. A symposium was held in 2005-2006 to identify priority actions for the conservation of the species.

Birdlife International

Current Conservation

Implement priority actions identified at the Buff-breasted Sandpiper symposium. Ascertain the population size and trend for the species. Complete a species action plan. Conserve key staging and wintering grasslands.

Asian Waterbird Census

Descriptions

The Asian Waterbird Census (AWC) was initiated in 1987 and runs in parallel with other waterbird censuses carried out in Africa, Europe, Central and West Asia and Latin America under the umbrella of the International Waterbird Census (IWC), which is organised by Wetlands International.

The AWC takes place annually, during the second and third weeks of January, and is carried out by volunteers interested in collecting information on waterbirds and wetlands as a basis for contributing to their conservation.
