The Common Sandpiper (Actitis hypoleucos) is a small Palearctic wader. This bird and its American sister species, the Spotted Sandpiper, make up the genus Actitis. They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize. Hybridization has also been reported between the Common Sandpiper and the Green Sandpiper, a basal species of the closely related shank genus Tringa.
Common Sandpiper in Kenya is a migrant, spending the Northern Hemisphere winter, July to April, along the Indian Ocean coast, shores of Rift Valley lakes, and along broad river banks. As it walks along hunting for invertibrates, it makes a distinctive bobbing gesture.
The common sandpiper forages by sight on the ground or in shallow water, picking up small food items such as insects, crustaceans and other invertebrates; it may even catch insects in flight.
