TheHudsonian whimbrel orHudsonian curlew (Numenius hudsonicus) is awader in the large familyScolopacidae. It is one of the most widespread of thecurlews, breeding across much ofsubarcticNorth America.[2]
This species and theEurasian whimbrel were split in 2019 based on genetic and morphological differences and separate breeding ranges.[2][3]
Two subspecies are recognized:[2]
This is a fairly large wader, though mid-sized as a member of the curlew genus. The English name is imitative of the bird's call.[4] The genus nameNumenius is fromAncient Greeknoumenios, a bird mentioned byHesychius. It is associated with the curlews because it appears to be derived fromneos, "new" andmene, "moon", referring to the crescent-shaped bill.
It is 37–47 cm (15–19 in) in length, 75–90 cm (30–35 in) in wingspan, and 270–493 g (9.5–17.4 oz; 0.595–1.087 lb) in weight. It is mainly greyish brown, with a rump pattern uniform with upperparts, and a long curvedbill (longest in the adult female) with a kink rather than a smooth curve.[5]
The usualcall is a rippling whistle, prolonged into a trill for the song.[citation needed]
The only similar common species over most of this bird's range are larger curlews. The whimbrel is smaller, has a shorter, decurved bill and has a central crown stripe and strong supercilia.[citation needed]
The Hudsonian whimbrel is amigratory coastal bird, wintering on coasts in southern North America andSouth America.[6] In the mangroves of Colombia, whimbrel roost sites are located in close proximity to feeding territories and away from potential sources of mainland predators, but not away from areas of human disturbance.[7]
This species feeds by probing soft mud for smallinvertebrates and by picking smallcrabs and similar prey off the surface. Before migration, berries become an important part of their diet.[citation needed]
The nest is a bare scrape ontundra or Arctic moorland. Three to five eggs are laid. Adults are very defensive of nesting area and will even attack humans who come too close.[citation needed]
Near the end of the 19th century, hunting on their migration routes took a heavy toll on this bird's numbers; the population has since recovered, although they are still classified as of High Conservation Concern in North America.[8]
