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]

Contents

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.

Breeding plumage

Non-Breeding plumage

Arenaria interpres
(Linnaeus, 1758)
circumpolar distribution, and is a very long distance migrant, wintering on coasts as far south as South Africa and Australia.
Arenaria interpres map.svg
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.

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.

<span class="mw-page-title-main">Sandpiper</span> Family of birds

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 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.

<span class="mw-page-title-main">Godwit</span> Genus of birds

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).
