Turnstones are two bird species that constitute the genus Arenaria in the family Scolopacidae. They are closely related to calidrid sandpipers and might be considered members of the tribe Calidriini. [1]
The genus Arenaria was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the ruddy turnstone (Arenaria interpres) as the type species. [2] [3] The genus name arenaria is from Latin arenarius, "inhabiting sand", from arena, "sand". [4]
The genus contains two species: the ruddy turnstone (Arenaria interpres) and the black turnstone (Arenaria melanocephala). [5] Both birds are waders. Their length is typically between 20 and 25 cm, with a wingspan between 50 and 60 cm and a body mass between 110 and 130g. For waders their build is stocky, with short, slightly upturned, wedge shaped bills. They have white patches on the back, wings and tail. 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. [6] They are strictly coastal, prefer stony beaches to sand, and often share beach space with other species of waders such as purple sandpipers.

ruddy turnstone | Arenaria interpres (Linnaeus, 1758) | circumpolar distribution, and is a very long distance migrant, wintering on coasts as far south as South Africa and Australia. | Size: It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. In breeding plumage, this is a showy bird, with a black-and-white head, chestnut back, white underparts and red legs. The drabber winter plumage is basically brown above and white below. Habitat: On coasts almost everywhere in the world Diet: This is a generally tame bird and is an opportunist feeder. Unlike most waders, it will scavenge, and has a phenomenal list of recorded food items, including human corpses and coconut. The call is a staccato tuck- tuck- tuck. | NT |
black turnstone | Arenaria melanocephala (Vigors, 1829) | Breeding in western Alaska, and wintering mainly on the Pacific coast of the United States. | Size: Black upperparts and chest, and white below. Habitat: Diet: | LC |
There exists a fossil bone, a distal piece of tarsometatarsus found in the Edson Beds of Sherman County, Kansas. Dating from the mid-Blancan some 4-3 million years ago, it appears to be from a calidriid somewhat similar to a pectoral sandpiper, but has some traits reminiscent of turnstones. [7] Depending on which traits are apomorphic and plesiomorphic, it may be an ancestral representative of either lineage.
A phalarope is any of three living species of slender-necked shorebirds in the genus Phalaropus of the bird family Scolopacidae.
Scolopacidae is a large family of shorebirds, or waders, which mainly includes many species known as sandpipers, but also others such as woodcocks, curlews and snipes. The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of bills enable different species to feed in the same habitat, particularly on the coast, without direct competition for food.
The skuas are a group of predatory seabirds with seven species forming the genus Stercorarius, the only genus in the family Stercorariidae. The three smaller skuas, the Arctic skua, the long-tailed skua, and the pomarine skua, are called jaegers in North American English.
Stilt is a common name for several species of birds in the family Recurvirostridae, which also includes those known as avocets. They are found in brackish or saline wetlands in warm or hot climates.
The curlews are a group of nine species of birds in the genus Numenius, characterised by their long, slender, downcurved bills and mottled brown plumage. The English name is imitative of the Eurasian curlew's call, but may have been influenced by the Old French corliu, "messenger", from courir , "to run". It was first recorded in 1377 in Langland's Piers Plowman "Fissch to lyue in þe flode..Þe corlue by kynde of þe eyre". In Europe, "curlew" usually refers to one species, the Eurasian curlew.
Godwits are a group of four large, long-billed, long-legged and strongly migratory waders of the bird genus Limosa. Their long bills allow them to probe deeply in the sand for aquatic worms and molluscs. In their winter range, they flock together where food is plentiful. They frequent tidal shorelines, breeding in northern climates in summer and migrating south in winter. A female bar-tailed godwit made a flight of 29,000 km (18,000 mi), flying 11,680 kilometres (7,260 mi) of it without stopping. In 2020 a male bar-tailed godwit flew about 12,200 kilometres (7,600 mi) non-stop in its migration from Alaska to New Zealand, previously a record for avian non-stop flight. In October 2022, a 5 month old, male bar-tailed godwit was tracked from Alaska to Tasmania, a trip that took 11 days, and recorded a non-stop flight of 8,400 miles (13,500 km).
The ruddy turnstone is a small cosmopolitan wading bird, one of two species of turnstone in the genus Arenaria.
The black turnstone is a species of small wading bird. It is one of two species of turnstone in the genus Arenaria the ruddy turnstone being the other. It is now classified in the sandpiper family, Scolopacidae, but was formerly sometimes placed in the plover family, Charadriidae. It is native to the west coast of North America and breeds only in Alaska.
The Eurasian curlew or common curlew is a very large wader in the family Scolopacidae. It is one of the most widespread of the curlews, breeding across temperate Europe and Asia. In Europe, this species is often referred to just as the "curlew", and in Scotland known as the "whaup" in Scots.
The Eurasian or common whimbrel, also known as the white-rumped whimbrel in North America, is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific.
The grey plover or black-bellied plover is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding.
The marbled godwit is a large migratory shorebird in the family Scolopacidae. On average, it is the largest of the four species of godwit.
The red-necked phalarope, also known as the northern phalarope and hyperborean phalarope, is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, winters at sea on tropical oceans.
The red phalarope or grey phalarope is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, migrates mainly on oceanic routes, wintering at sea on tropical oceans.
The collared pratincole, also known as the common pratincole or red-winged pratincole, is a wader in the pratincole family, Glareolidae. As with other pratincoles, it is native to the Old World.
The Terek sandpiper is a small migratory Palearctic wader species and is the only member of the genus Xenus. It is named after the Terek River which flows into the west of the Caspian Sea, as it was first observed around this area.
Pluvialis is a genus of plovers, a group of wading birds comprising four species that breed in the temperate or Arctic Northern Hemisphere.
Gallinago is a genus of birds in the wader family Scolopacidae, containing 18 species.
The surfbird is a small stocky wader in the family Scolopacidae. It was once considered to be allied to the turnstones, and placed in the monotypic genus Aphriza, but is now placed in the genus Calidris.
The giant snipe is a stocky wader. It breeds in South America. The nominate subspecies G. u. undulata occurs in two distinct areas, one in Colombia, and the other from Venezuela through Guyana, Suriname and French Guiana to extreme north-eastern Brazil. The southern subspecies G. u. gigantea is found in eastern Bolivia, eastern Paraguay and south-east Brazil, and probably also in Uruguay and north-eastern Argentina.
