Calidris acuminata (Sharp-tailed sandpiper) is a small, long-distance migrant that breeds in the boggy tundra of northeast Asia and is strongly migratory, wintering in south-east Asia and Australasia. It is a rare migrant to New Zealand.
It is a portly sandpiper with a flat back, pot belly and somewhat drawn-out rear end. It has a small flat head on a short neck with a short and slightly decurved bill. Their body length is 22 cm (bill tip to tail), a wingspan of 36–43 cm and a weight of 65 g.
These birds forage on grasslands and mudflats, picking up food by sight, sometimes by probing. They mainly eat insects and other invertebrates.
