Eurasian Curlew (Numenius arquata)

(Shetlands, June 2013) It is a wader in the large family Scolopacidae. This is the largest wader in its range, at 50–60 cm in length, with a 89–106 cm 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.
Habitat:

It exists as a migratory species over most of its range, wintering in Africa, southern Europe and south Asia. Occasionally a vagrant individual reaches places far from its normal range, such as Nova Scotia and the Marianas. It is present all year in the milder climates of the United Kingdom and its adjacent European coasts. 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 arises.
