The Eurasian Curlew, Numenius arquata, is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across temperate Europe and Asia. In Europe, this species is often referred to just as "the Curlew", and in Scotland known as the "whaup" in Scots.
This is the largest wader in its range, at 50–60 cm in length, with a 89–106 cm in wingspan and a body weight of 410–1,360 g. It is mainly greyish brown, with a white back, 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 recognize the sex of a single Eurasian Curlew, or even several ones as there is much variation; telling male and female of a mated pair apart is usually possible however.
The familiar call, from which this bird gets it name, is a loud curloo-oo.
The nest is a bare scrape on taiga, meadow or similar habitat. 3-6 eggs are laid in April/May, and incubated for about a month to hatching.
