The Surfbird (Calidris virgata) is a robust and distinctive medium-sized shorebird, measuring approximately 23-26 cm (9-10 in) in length with a wingspan of 46-56 cm (18-22 in) and weighing 130-250 g (4.6-8.8 oz).

Primarily found on rocky coastal shores, jetties, and breakwaters during non-breeding seasons; it breeds in high Arctic alpine tundra and open taiga environments.
Primarily feeds on marine invertebrates, including limpets, mussels, barnacles, crustaceans, and marine worms, obtained by prying and probing rocky intertidal zones.
Surfbirds are highly diurnal foragers, diligently active during low tide, but can also be seen roosting in dense flocks on offshore rocks or less exposed areas during high tide. Their foraging strategy is unique, often involving prying limpets, mussels, and barnacles from rocks using their stout ...
The Surfbird exhibits a remarkable migratory journey, breeding exclusively in the remote, high-latitude alpine tundra and open taiga of Alaska and Yukon, predominantly above the tree line. After a short breeding season, they undertake a spectacular southward migration, following the Pacific Flywa...
