'The ecology and behavior of the Long-billed Curlew (Numenius americanus) in southeastern Washington' -- subject(s): Long-billed curlew

The curlews are a group of birds with the physical characteristics of a long, slender, down-curved bill and brown feathers. The eight species of birds that belong to curlews include Numenius phaeopus, aquata, tenuirostris, amricanus, madagascariensis, minutus, borealis, and tahitiensis.

The eskimo Curlew is probably although not confirmed to be extinct. According to Thomas et al, "Can intrinsic factors explain population declines in North American breeding shorebirds? A comparative analysis," in Animal Conservation Volume 9 Issue 3, Pages 252 - 258, its decline is probably due to large-scale habitat change. The conversion of upland areas (along with suppression of fire) into agriculture is one of the main reasons for the extinction of the Eskimo curlew Numenius borealis, a continental migrant whose numbers plummeted during the late 1800s and early 1900s.
