Surfbird (Calidris virgata)

The Surfbird is a medium-sized coastal bird that appears in September in the Pacific Coast of Costa Rica, as they migrate towards the south to escape from winter. They are mainly grayish-brown on the upperparts, throat and chest, white with some dark spots on the underparts, bright yellow legs and a relatively small black bill with a little yellow on the base. Its color pattern helps them camouflage easily among the dark shore rocks.
