The spoon-billed sandpiper (Calidris pygmaea) is a small wader which breeds in north-eastern Russia and winters in Southeast Asia.
This species was first described by Linnaeus in his Systema Naturae in 1758 as Platalea pygmea. It was later moved to Eurynorhynchus by Sven Nilsson in 1821. It is now classified under the calidrid sandpipers.
The most distinctive feature of this species is its spatulate bill. The breeding adult bird is 14–16 cm in length, and has a red-brown head, neck and breast with dark brown streaks. It has blackish upperparts with buff and pale rufous fringing. Non-breeding adults lack the reddish colouration, but have pale brownish-grey upperparts with whitish fringing to the wing-coverts. The underparts are white and the legs are black.
The measurements are; wing 98–106 mm, bill 19–24 mm, bill tip breadth 10–12 mm, tarsus 19–22 mm and tail 37–39 mm.
The contact calls of the spoon-billed sandpiper include a quiet preep or a shrill wheer. The song, given during display, is an intermittent buzzing and descending trill preer-prr-prr. The display flight of the male includes brief hovers, circling and rapid diving while singing.
The spoon-billed sandpiper's breeding habitat is sea coasts and adjacent hinterland on the Chukchi Peninsula and southwards along the isthmus of the Kamchatka peninsula It migrates down the Pacific coast through Japan, North Korea, South Korea and China, to its main wintering grounds in South and South-East Asia, where it has been recorded from India, Bangladesh, Sri Lanka, Burma, Thailand, Vietnam, the Philippines, Peninsular Malaysia and Singapore.
