Eurasian Curlew (Numenius arquata)

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 (20–24 in) in length, with a 89–106 cm (35–42 in) wingspan and a body weight of 410–1,360 g (0.90–3.00 lb). 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 only similar species over most of the Curlew’s range is the Whimbrel (N. phaeopus). The Whimbrel is smaller and has a shorter bill with a kink rather than a smooth curve. Flying Curlews may also resemble, albeit not existing in the same area, Bar-tailed Godwits (Limosa lapponica) in their winter plumages; however, the latter have a smaller body, a slightly upturned beak, and legs that do not reach far beyond their tail tips. The Eurasian Curlew’s feet are longer, forming a conspicuous “point”.

It is generally wary. Highly gregarious outside the breeding season, the Eurasian Curlew feeds by probing soft mud for small invertebrates, but will also pick small crabs and earthworms off the surface if the opportunity arise.

The nest is a bare scrape on taiga, meadow, and similar habitats. Each Curlew lays between 3 and 6 eggs in April or May and incubates them for about a month until they begin to hatch.
