Diet
The pectoral sandpiper walks with its head down foraging for food on the ground. Sometimes it probes for food in the mud. During the breeding season, it eats
flies, larvae, spiders, and seeds.
During migration, it eats small
crustaceans and other aquatic invertebrates
Life Cycle
Male and female pectoral sandpipers may mate with more than one partner. The males arrive on the breeding ground first and establish a territory. The male tries to attract females with a display flight. During the flight, he expands and contracts his throat sac and makes a series of hooting sounds! The female builds a scrape in a slightly raised grassy area on the ground and lines it with grass and leaves. The nest is usually hidden by vegetation or is made under a bush. The female lays four eggs and incubates them for 21-23 days. The chicks are
precocial and can feed themselves shortly after hatching. The female stays with the chicks for 10-20 days. She usually leaves them before they fledge at 21 days.
Behavior
The pectoral sandpiper is a long-distance migrator. It travels as much as 9,000 miles each way to its breeding and wintering grounds.
