Crown is dark brown; neck, face, breast and upper flanks are streaked; legs are yellow, green or brown. Faint wing bar and black rump with white edges are visible in flight. Sexes are similar. Female is smaller with a paler breast. Juvenile has pale buff heavily streaked breast; upperparts have paler, narrower fringes that make a V across the mantle and scapulars.
Range and Habitat
Pectoral Sandpiper: Breeds on arctic tundra from western Alaska across extreme northern Canada to the Hudson Bay; also found in Siberia. Spends winters in South America and Australia. During migration, may occur throughout North and Central Americas. Preferred habitats include marshes and grassy pools.
Breeding and Nesting
Pectoral Sandpiper: Four white to olive buff eggs blotched with dark brown are laid in a cup of grass and leaves hidden on the ground. Female incubates the eggs for 21 to 23 days.
Foraging and Feeding
Pectoral Sandpiper: Their diet includes freshwater, marine and terrestrial invertebrates, and occasionally seeds and algae. They probe, jab and peck items from the substrate, often while walking slowly. They probe by inserting the entire length of their bill and jab to locate prey, presumably on the basis of tactile senses; they peck at surface-active prey using visual cues.
Vocalization
Pectoral Sandpiper: Call is a rich, low "churrrt", "krrrek", or "tik-tik-tik". The male uses an inflatable air sac to vocalize during courtship displays.
