Behaviour

Western sandpipers feed in tight flocks, probing mud and licking biofilm from the surface.

Why they matter

Although it breeds in Alaska, the western sandpiper is one of the most common small shorebirds wintering on the Southeast coast, showing how birds from the far west use Georgia's shores.

Reproduction and lifecycle

Nest — A scrape on tundra
Eggs — Usually four
Incubation — About 21 days
Chicks — Leave the nest within a day
Flight — At about 17 to 21 days
Lifespan — Several years

Living around people

  • Mudflats kept free of disturbance at low tide let flocks feed efficiently.

Misconceptions

  • A bird that breeds in Alaska would not winter in Georgia. Western sandpipers do, every year.
