The Wood Sandpiper is wary and nervous and will burst into flight if disturbed, zig-zagging off and calling loudly, then gliding gracefully to ground again.
The Wood Sandpiper is a small slim wader, dark grey-brown above, with light flecks or spots, and a white underbody. The light breast is mottled as well. The legs are yellow-green. There is a distinct white brow line. The flight is strong, with distinctive clipped wing beats. In flight, a square white rump is revealed and there are no wing bars.
The Wood Sandpiper is similar in size to the Sharp-tailed Sandpiper, Calidris acuminata, but is slimmer and has a longer, finer bill and longer legs. The distinctive white rump of the Wood Sandpiper is obvious in flight and the feet project well beyond the tail.
Wood Sandpipers are more numerous in the north than the south of Australia and are also found in New Guinea, Africa, the Indian subcontinent and South-east Asia. They breed widely across the north of Europe and Asia, mostly in Scandinavia, Baltic countries and Russia. They are the most abundant migratory wader in non-coastal areas of Asia.
Wood Sandpipers are seen in small flocks or singly on inland shallow freshwater wetlands, often with other waders. They prefer ponds and pools with emergent reeds and grass, surrounded by tall plants or dead trees and fallen timber.
This is a migratory species, moving south after breeding to Africa and South Asia. The Australian population probably breeds in east Siberia. There is some movement in Australia. They leave the breeding areas by early September and are mostly seen in Australia between August and April. Small numbers of birds remain in Australia over winter.
Wood Sandpipers feed mainly on aquatic insects and their larvae and molluscs in moist or dry mud. They high-step daintily through shallow water, probing in mud or picking at the surface. They also swim well and may feed by sweeping their bill from side to side under water.
Wood Sandpipers nest in a variety of habitats in their northern breeding grounds, including pine forests, open tundra, marshes or bogs. The nest is a shallow depression lined with grass and leaves, sometimes even in the old nest of a songbird. The display during breeding is a switchback flight in the air, then a glide back to ground with short trilling calls.
Wood Sandpipers have benefited from irrigation schemes and open sewage ponds and other artificial wetlands. Threats on the East Asian-Australasian Flyway (the migration route to Australia) include economic and social pressures such as wetland destruction and change, pollution and hunting.
