Range and Habitat
Gray-tailed Tattler: Breeds in northeast Siberia. Occurs as a regular spring and fall migrant on the outer Aleutian Islands, Pribilofs, and St. Lawrence Island, and casually on the Alaskan coast, north to Point Barrow; there are single records from Washington and California. Strongly migratory, spending winter months in Southeast Asia and Australia.
Breeding and Nesting
Gray-tailed Tattler: Breeding grounds for this species are found in stony riverbeds. They are generally ground-nesting birds. Four light blue eggs speckled with black are laid on bare ground sheltered by rocks. They sometimes use an abandoned thrush nest. Incubation ranges from 24 to 25 days and is carried out by both parents.
Foraging and Feeding
Gray-tailed Tattler: They locate their prey by sight and can be seen bobbing and teetering as they dart around, foraging for worms, mollusks, crustaceans, insects and occasionally fish. Before it migrates to its Siberian mating grounds, it is believed that crabs play an increasingly important role in its diet. They forage either alone or in loose groups.
Vocalization
Gray-tailed Tattler: Bold, rising "tu-weeeeeet" call. Alarm call is a sharp "klee-klee."
