Areale e habitat

The solitary snipe breeds discontinuously in the mountains of eastern Asia, in eastern Russia, Kazakhstan, Kyrgyzstan and Mongolia. Many birds are sedentary in the high mountains, or just move downhill in hard weather, but others are migratory, wintering in northeast Iran, Pakistan, northern India, Bangladesh, eastern China, Korea, Japan and Sakhalin.

Comportamento

This snipe breeds in mountain bogs and river valleys above the timberline, typically from 2,400 m to 5000 m. It is often found in similar marshes and swamps at lower altitudes when not breeding or on migration.<p>The solitary snipe builds a saucer-shaped nest of dry grass in the drier areas of its breeding wetland. The nest is concealed in a dense tuft of grass or sedges.<p>This bird has an aerial display, which involves flying high in circles, followed by a powerful stoop during which the bird makes a "drumming" sound, caused by vibrations of modified outer tail feathers.<p>The solitary snipe forages by pushing its long bill deep into the mud seeking invertebrates, such as insects and worms, seeds and plants. It is quite approachable, but if alarmed, it crouches, and its cryptic plumage provides effective camouflage when the bird stands motionless amongst marsh vegetation. When flushed, it drops back into the marsh after a short slow flight.
