Sharp-tailed Sandpiper

The sharp-tailed sandpiper is a small-to-medium migratory wader found mostly in Siberia during the summer breeding period (June to August) and in Australia for wintering (September to March). Its plumage is more vivid in the breeding season and duller in winter. The most similar-looking species is the pectoral sandpiper, within whose Asian range it breeds (Wikipedia, general species account).

It is strongly migratory and breeds only in eastern Siberia. The clutch is usually four eggs, with the females incubating and raising the chicks. Birds are thought to fatten up from mid-August to late October and then make a direct, non-stop trans-Pacific flight of more than 10,000km to Australia and New Zealand (Wikipedia, general species account).
