Behaviour

Sanderlings chase receding waves to probe for tiny crabs and clams, then sprint back ahead of the next wave. They lack a hind toe, which may help them run.

Why they matter

Sanderlings breed in the high Arctic and winter on beaches across the world. They are among the most familiar shorebirds on Georgia's beaches, and they depend on the tiny animals of the surf zone that also feed fish.

Reproduction and lifecycle

Nest — A scrape on Arctic tundra
Eggs — Usually four
Incubation — About 24 to 32 days
Chicks — Leave the nest within a day
Flight — At about 17 days
Lifespan — Wild birds over twelve years are recorded

Living around people

  • Chasing flocks on the beach, by children or dogs, costs sanderlings energy they need for winter and migration.

Misconceptions

  • Birds running from waves are playing. They are feeding, snatching prey exposed in the wet sand.
