Pectoral Sandpiper

The pectoral sandpiper is a medium-sized Calidris wader, measuring nineteen to twenty-three centimetres long with a thirty-seven to forty-six centimetre wingspan. Its back is grey-brown, becoming browner in breeding males and greyer in winter. The grey breast ends in a conspicuously sharp boundary above a white belly, the feature behind its English name. Yellowish legs, an olive bill with a dark tip, a weak eyebrow and relatively subdued crown help separate it from the similar sharp-tailed sandpiper. (Wikipedia, general species account)

This long-distance migrant breeds on boggy tundra in northern Asia and from Alaska into central Canada. Most Asian and American birds winter in South America, although some Asian breeders travel to Australia and New Zealand. During migration and winter it generally uses freshwater habitats, feeding on grassland and mudflats by sight or by probing. Its food includes flies and their larvae, spiders, crustaceans, other invertebrates and seeds. The female places four eggs in a deeply lined ground scrape that reduces heat loss in Arctic winds.
