There are 3 races of Eurasian Curlews, which are a partly migratory
species.
Altogether, their breeding areas lie in western, central and northern
Europe (race "arquata"),
in western and central Siberia and further
to the East in north-eastern China (race "orientalis") and from
western Kazakhstan to southwestern Siberia (race "schuschkini").
Many birds, in particular in the southern parts of their breeding
ranges, can be sedentary. Others, mostly from the northern parts
of the breeding range, will spend the winters further South, e.g.
around the western European and Mediterranean coastline or parts
of the North-African coastline. There are also wintering grounds
on the East coast of the Black Sea, the South coast of the Caspian Sea
and around the Red Sea and the Persian Gulf, around the Indian
subcontinent and into parts of South-east Asia. In the far East
there are wintering areas along the coastline of China, Taiwan,
Korea and Japan. They are less commonly found in the south-eastern
Asian island nations.
In Arabia Eastern Curlews, race "orientalis",
are found as winter visitors, with most birds being found
in Qatar, the UAE and northern Oman, but in principle they
can be found almost all around the Arabian coastline.
Outside the breeding season Eurasian Curlews are often found
in coastal habitats, such as beaches, estuaries and mudflats.
During the breeding season they are more common around fresh
water, in swamps and marshes.
