Hudsonian Whimbrel
Numenius hudsonicus
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. The genus name Numenius is from Ancient Greek noumenios, a bird mentioned by Hesychius. It is associated with the curlews because it appears to be derived from neos, "new" and mene, "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.

Little Curlew
Numenius minutus
It is mainly greyish-brown, including the underwings, with a white belly, and a short, for a curlew, curved bill. It has a head pattern like a Eurasian whimbrel, with crown and superciliary stripes. The call is a repetitive whistle. It is the smallest species of curlew with an average length of 28–31 cm (11–12 in), an average wingspan of 68–71 cm (27–28 in) and an average weight of 175 grams (6.2 oz).
