The Black Turnstone breeds in Western and Southern Alaska on the coastal plain. It winters only on the Pacific coast, from southeast Alaska to central Mexico. It is the most abundant shorebird of rocky shorelines. Favourite habitats include reefs, rocky beaches, jetties, and gravel bars at the mouths of rivers or along lagoons. It may also forage on adjacent mudflats wet sandy beaches, floating kelp beds, and piles of washed-up seaweed. Black Turnstones have been recorded roosting on dry rocks, jetties, and floating log booms at which time they may gather into extremely dense flocks.
It is widely distributed along the inner and outer coast. Its distribution is largely restricted to rocky coastal shorelines, but it frequents many fiords and protected inlets. It is a vagrant in the interior. The Black Turnstone usually occurs in flocks of 10 to 30 birds at Race Rocks where it overwinters.
