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. 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 15,000 individuals5. 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. 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. It appears to depend heavily upon intensive grazing by livestock4. CMS Appendix I and II.
