Eurasian Curlew
Numenius arquata
The Eurasian curlew is the largest wading bird in its range. It is 50–60 cm (20–24 in) long, has a wingspan of 89–106 cm (35–42 in) wingspan and weighs 410–1,360 g (0.90–3.00 lb). It is mainly greyish brown, with a white back, greyish-blue legs and a very long curved bill. Males and females look identical, but the bill is longest in the adult female. It is generally not possible to determine the sex of an individual Eurasian curlew, or even of several, as there is much variation. However, it is usually possible to tell the sexes apart in a mated pair. The familiar call is a loud curloo-oo.

Long-billed Curlew
Numenius americanus
The long-billed curlew is the largest sandpiper of regular occurrence in North America. It is 50–65 cm (20–26 in) long, 62–90 cm (24+1⁄2–35+1⁄2 in) across the wing and weighs 490–950 g (1 lb 1+1⁄2 oz – 2 lb 1+1⁄2 oz). Its disproportionally long bill curves downward and measures 11.3–21.9 cm (4+1⁄2–8+5⁄8 in), and rivals the bill of the larger-bodied Far Eastern curlew as the longest bill of any shorebird. Individuals have a long neck and a small head. The neck and underparts are a light cinnamon in color, while the crown is streaked with brown.
