NationMaster - Encyclopedia: Wader

Waders, called Shorebirds in North America (where "wader" is used to refer to long-legged wading birds such as storks and herons), are members of the order Charadriiformes, excluding the more marine web-footed seabird groups. The latter are the skuas (Stercoraracidae), gulls (Laridae), terns (Sternidae), skimmers (Rhynchopidae), and auks (Alcidae). Also, the pratincoles (Glareolidae) and the Crab Plover (Dromadidae), which look more similar to waders, are closely related to the seabirds.

This leaves about 210 species, most of which are associated with 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 the Arctic species, such Little Stint are amongst the longest distance migrants, spending the non-breeding season in the southern hemisphere.

The majority of species eat small invertebrates picked out of mud or exposed soil. Different lengths of bills enable different species to feed in 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. Invertebrate is a term coined by Jean-Baptiste Lamarck to describe any animal without a spinal column. ...

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. † see also: wader The calidrids and their allies are a group of Arctic breeding, strongly migratory wading birds. ...

In the Sibley-Ahlquist taxonomy, waders and many other groups are subsumed into a greatly enlarged Ciconiiformes order. 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 formed the suborder Charadrii, but this has turned out to be a "wastebin taxon", uniting no less than four charadriiform lineages in a paraphyletic assemblage. 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: The Sibley-Ahlquist taxonomy is a radical bird taxonomy based on DNA-DNA hybridization studies conducted in the late 1970s and throughout the 1980s. ... Families Ardeidae Cochlearidae Balaenicipitidae Scopidae Ciconiidae Threskiornithidae Traditionally, the order Ciconiiformes has included a variety of large, long-legged wading birds with large bills: storks, herons, egrets, ibises, spoonbills, and several others. ...

In keeping more in line with the traditional grouping, the Thinocori could be included in the Scolopaci, and the Chionidi in the Charadrii. However, the increasing knowledge about the early evolutionary history of modern birds suggests that the assumption of Paton et al. (2003) and Thomas et al. (2004b) of 4 distinct "wader" lineages (= suborders) already being present around the C-T boundary is correct.
