Critically Endangered
Eskimo Curlew
Numenius borealis
Eskimo Curlew is a shorebird in the family Scolopacidae (order Charadriiformes) — Numenius borealis, recorded as Critically Endangered.
Appearance
Adults have long dark greyish legs and a long bill curved slightly downward. The upperparts are mottled brown and the underparts are light brown. The Eskimo curlew forms a species pair with the Asian little curlew (Numenius minutus), but is slightly larger, longer-winged, shorter legged, and warmer in plumage tone than its Asian relative.
Eskimo curlews are small curlews, about 30 centimetres (12 in) in length, weighing approximately 360 g (13 oz), and having a wingspan of 70 cm (28 in).
Range and habitat
In the 1800s, millions of Eskimo curlews followed migration routes from the present Yukon and Northwest Territories, flying east along the northern shore of Canada, then south over the Atlantic Ocean to South America in the winter.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet and breeding
Eskimo curlews pick up food by sight, and feed by probing. During the rest of their migration and on the breeding grounds, they eat insects.
Snails and other invertebrates (among them the extinct Rocky Mountain locust) also are part of their diet during migration.
In crisis
As there has not been a reliable sighting since 1987 or a confirmed sighting since 1963, the Eskimo curlew is considered Critically Endangered or possibly extinct.
CITES lists this taxon on Appendix I. Confirm the current appendix on the CITES checklist.
