Numenius arquata

There are two subspecies, Eurasian Curlew.

It is a summer migratory bird in northeastern Inner Mongolia, Heilongjiang and Jilin, and specimens were collected in eastern Liaoning in April and May, and may also breed. Wintering in the middle and lower reaches of Yangtze River and southeast coastal provinces of China. The time to move to the northeast breeding ground in spring is from early April to mid-April, and the time to leave the breeding ground in autumn is from early October to late October, and a few are seen in the northeast breeding ground as late as early November.

Curlews often move in small groups. Sexual alertness, slow and steady activity, from time to time to look around, find danger, fly away immediately, and accompanied by a 'go-ee' call. Powerful flight, slow flapping of the wings. It feeds mainly on crustaceans, mollusks, worms, insects and insect larvae, but also pecks at small fish and frogs. They often dig their long, downward curved mouths into the mud as they walk.

The breeding period is from May to July. By the end of April, couples will be seen and courtship flights will take place. Nest building begins in early May. They usually nest in forests near open swampy wetlands, lakes and streams, sometimes 2-3 km away from the water. The nest is mostly located on dry ground or in a dry place on a mound in a swamp. The nest is very simple, mainly using natural pits on the ground or making a pit on the ground with dead grass inside. There are usually 4 eggs per clutch, but occasionally as few as 3 eggs and as many as 5 or even 6 eggs. The eggs are green or olive yellow in color with brown spots. The size of the eggs is 66.5-71 x 46-50 mm. Male and female birds incubate eggs in turn, if there is disturbance when incubating eggs, birds often bend their backs and lower their bodies to secretly leave the nest, generally do not take off. Incubation period is 28-30 days.

The number of white curlew is rare and not widespread, and several key communities and the whole are in moderate and rapid decline globally, which should be protected.
