25-448: The common greenshank ( Tringa nebularia ) is a wader in the large family Scolopacidae, the typical waders. The genus name Tringa is the Neo-Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas , a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle . The specific nebularia is from Latin nebula "mist". Like
50-465: A paraphyletic assemblage. However, it indicated that the plains wanderer actually belonged into one of them. Following recent studies (Ericson et al., 2003; Paton et al., 2003; Thomas et al., 2004a, b; van Tuinen et al., 2004; Paton & Baker, 2006), the waders may be more accurately subdivided as follows, with Charadrii being repurposed into a monophyletic suborder of plovers, oystercatchers, and their close relatives. The waders are traditionally
75-562: A greatly enlarged order Ciconiiformes . However, the classification of the Charadriiformes is one of the weakest points of the Sibley-Ahlquist taxonomy, as DNA–DNA hybridization has turned out to be incapable of properly resolving the interrelationships of the group. Formerly, the waders were united in a single suborder Charadrii , but this has turned out to be a " wastebasket taxon ", uniting no fewer than four charadriiform lineages in
100-404: A ground scrape. Common greenshanks are brown in breeding plumage, and grey-brown in winter. When in water, they can appear very similar to marsh sandpipers but are distinguished by the shape of the lower bill which gives it an upturned appearance to the bill. They have long greenish legs and a long bill with a grey base. They show a white wedge on the back in flight. They are somewhat larger than
125-530: A group of two Charadriiform suborders which include 13 families . Species in the third Charadriiform suborder, Lari , are not universally considered as waders, though the Larine families which may variously be included are listed below as well. Shorebirds is a blanket term used to refer to multiple bird species that live in wet, coastal environments. Because most these species spend much of their time near bodies of water, many have long legs suitable for wading (hence
150-403: A result, an increase in dimorphism. Bigger males tend to have greater access (and appeal) to female mates because their larger size aids them in defeating other competitors. Likewise, if the species exhibits gender role reversal (where males take on roles traditionally done by females such as childcare and feeding), then males will select female mates based on traits that are the most appealing. In
175-443: A single female partner, males typically do not have distinctive dimorphic characteristics such as colored feathers, but they still tend to be larger in size compared to females. The suborder Charadrii displays the widest range of sexual dimorphisms seen in the order Charadriiformes. However, cases of sexual monomorphism, where there are no distinguishing physical features besides external genitalia, are also seen in this order. One of
200-465: Is a large shorebird most similar in appearance to the long-billed curlew , but slightly larger. It is mostly brown in color, differentiated from other curlews by its plain, unpatterned brown underwing. It is not only the largest curlew but probably the world's largest sandpiper , at 60–66 cm (24–26 in) in length and 110 cm (43 in) across the wings. The body is reportedly 565–1,150 g (1.246–2.535 lb), which may be equaled by
225-668: Is altogether more robustly built. The greater yellowlegs and the common greenshank share a coarse, dark, and fairly crisp breast pattern as well as much black on the shoulders and back in breeding plumage. This is a subarctic bird, breeding from northern Scotland eastwards across northern Europe and east across the Palearctic . It is a migratory species, wintering in Africa, the Indian subcontinent, and Australasia, usually on fresh water. It breeds on dry ground near marshy areas, laying about four eggs in
250-571: Is the least sandpiper , small adults of which can weigh as little as 15.5 grams (0.55 oz) and measure just over 13 centimetres (5 inches). The largest species is believed to be the Far Eastern curlew , at about 63 cm (25 in) and 860 grams (1 pound 14 ounces), although the beach thick-knee is the heaviest at about 1 kg (2 lb 3 oz). In the Sibley-Ahlquist taxonomy , waders and many other groups are subsumed into
275-617: The Eurasian curlew . The extremely long bill, at 12.8–20.1 cm (5.0–7.9 in) in length, rivals the bill size of the closely related long-billed curlew as the longest bill for a sandpiper. In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Far Eastern curlew in his Ornithologie based on a specimen. He used the French name Le courly de Madagascar and

#1732898428165300-462: The Jacana species, females compete with each other for access to male mates, so females are larger in size. Males choose female mates based on who presents herself as the strongest and who 'owns' the most territory. Another factor that leads to the development of dimorphisms in species is natural selection . Natural selection focuses on traits and the environment's response to the traits in question; if
325-481: The Arctic species, such as the little stint , are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere . Many of the smaller species found in coastal habitats, particularly but not exclusively the calidrids , are often named as "sandpipers", but this term does not have a strict meaning, since the upland sandpiper is a grassland species. The smallest member of this group
350-926: The Australian EPBC Act. Wader Waders or shorebirds are birds of the order Charadriiformes commonly found wading along shorelines and mudflats in order to forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans . The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons . There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory , but tropical birds are often resident, or move only in response to rainfall patterns. Some of
375-531: The Far Eastern curlew commonly makes stopovers on the mudflats of the Yellow Sea . It uses its long, decurved bill to probe for invertebrates in the mud. It may feed in solitary but it generally congregates in large flocks to migrate or roost. Its call is a sharp, clear whistle, cuuue-reee , often repeated. On its breeding grounds the Far Eastern curlew consumes insects, such as larvae of beetles and flies, and amphipods. During migration it also feeds on berries. In
400-574: The Latin Numenius madagascariensis . Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature . When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition , he added 240 species that had been previously described by Brisson. One of these
425-475: The Norwegian Skoddefoll , this refers to the greenshank's damp marshy habitat. Its closest relative is the greater yellowlegs , which together with the spotted redshank form a close-knit group. Among them, these three species show all the basic leg and foot colours found in the shanks , demonstrating that this character is paraphyletic . They are also the largest shanks apart from the willet , which
450-489: The biggest factors that leads to the development of sexual dimorphism in shorebirds is sexual selection . Males with ideal characteristics favored by females are more likely to reproduce and pass on their genetic information to their offspring better than the males who lack such characteristics. Mentioned earlier, male shorebirds are typically larger in size compared to their female counterparts. Competition between males tends to lead to sexual selection toward larger males and as
475-477: The name 'Waders'). Some species prefer locations with rocks or mud. Many shorebirds display migratory patterns and often migrate before breeding season. These behaviors explain the long wing lengths observed in species, and can also account for the efficient metabolisms that give the birds energy during long migrations . The majority of species eat small invertebrates picked out of mud or exposed soil. Different lengths of bills enable different species to feed in
500-450: The non-breeding season, it consumes marine invertebrates, preferring crabs and small molluscs but also taking other crustaceans and polychaetes. As of 2006, there are an estimated 38,000 individuals in the world. Formerly classified as least concern by IUCN, it was found to have been rarer than previously believed and thus its status was uplisted to "vulnerable" in the 2010 IUCN Red List of threatened species. In Australia its status under

Like most waders, they feed on small invertebrates , but will also take small fish and amphibians. The common greenshank is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. In 2024, T. nebularia was listed as Endangered under

#1732898428165550-435: The said trait increases the overall fitness of the individual possessing it, then it will be 'selected' and eventually become a permanent part of the population's gene pool. For example, depending on the food available in a shorebird specie's respective niche , bigger bill sizes may be favored in all individuals. This would essentially lead to monomorphism within the species but is subject to change once sexual selection acts on
575-818: The same habitat, particularly on the coast, without direct competition for food. Many waders have sensitive nerve endings at the end of their bills which enable them to detect prey items hidden in mud or soft soil. Some larger species, particularly those adapted to drier habitats will take larger prey including insects and small reptiles . Shorebirds, like many other animals, exhibit phenotypic differences between males and females, also known as sexual dimorphism . In shorebirds, various sexual dimorphisms are seen, including, but not limited to, size (e.g. body size, bill size), color, and agility. In polygynous species, where one male individual mates with multiple female partners over his lifetime, dimorphisms tend to be more diverse. In monogamous species, where male individuals mate with
600-534: The trait. Sexual selection could give rise to males with relatively larger bills than females if males used their bills to compete with other males. If larger bill size assisted the male in gathering resources, it would also make him more attractive to female mates.

The Far Eastern curlew spends its breeding season in northeastern Asia, including Siberia to Kamchatka , and Mongolia . Its breeding habitat is composed of marshy and swampy wetlands and lakeshores. Most individuals spend the non-breeding season in coastal Australia , with a few heading to South Korea , Thailand , Philippines and New Zealand , where they stay at estuaries , beaches, and salt marshes .
