The pectoral sandpiper, often abbreviated pec, is a small, migratory wader that breeds in arctic regions of North America and Asia, wintering in South America and Oceania. It eats small invertebrates. Its nest, a hole scraped in the ground and with a thick lining, is deep enough to protect its four eggs from the cool breezes of its breeding grounds. The pectoral sandpiper is 19–23 cm (7.5–9.1 in) long, with a wingspan of 38–46 cm (15–18 in).
