Pectoral Sandpiper

The pectoral sandpiper, often abbreviated 'pec', is a small, migratory wader that breeds in arctic regions of North America and Asia and winters in South America and Oceania. It is 19–23cm long with a wingspan of 38–46cm. It looks similar to the sharp-tailed sandpiper, which is not in the same clade, and has yellowish legs and an olive bill with a darker tip (Wikipedia, general species account).

It eats small invertebrates. The nest, a hole scraped in the ground with a thick lining, is deep enough to protect its four eggs from the cool breezes of its breeding grounds. Males are on average heavier than females, with much overlap (Wikipedia, general species account).
