Turnstones

Turnstones are two bird species that comprise the genus Arenaria in the family Scolopacidae. They are closely related to calidrid sandpipers and might be considered members of the tribe Calidriini. The genus name arenaria is from Latin arenarius, "inhabiting sand, from arena, "sand". Both birds are distinctive medium-sized waders. Roughly speaking, length is typically between 20 and 25 cm, with a wingspan between 50 and 60 cm and a body mass between 110 and 130gm. For waders their build is stocky, with short, slightly upturned, wedge shaped bills. They are high Arctic breeders, and are migratory. Their strong necks and powerful, slightly upturned bills are adapted to their feeding technique. As the name implies, these species overturn stones, seaweed, and similar items in search of invertebrate prey. They are strictly coastal, prefer stony beaches to sand, and often share beach space with other species of waders such as purple sandpipers.
