The Wilson’s Plover is a small migratory bird that can be spotted in early September at the Pacific Coast of Costa Rica. The upperparts are gray-brown, with a white collar around the neck, white forehead, black mask on the face and small bill with orange basal half and black tip. The underparts are mostly white, except for a black breast band. The delicate legs are orange. It looks very similar to the bigger Killdeer. They wade in beaches and shallow mud flats where they can grab crabs and small insects.
