Suborders

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 Semipalmated Sandpiper, Calidris pusilla, is a very small Shorebird. Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. Charadriiformes is a diverse order of small to medium-large Birds It includes about 350 Species and has members in all parts of the world This article is about the taxonomic rank for the sequence of species in a taxonomic list see Taxonomic order In scientific classification used Waders, called shorebirds in North America (where "wader" is used to refer to long-legged wading Birds such as Storks and Waders, called shorebirds in North America (where "wader" is used to refer to long-legged wading Birds such as Storks and Waders, called shorebirds in North America (where "wader" is used to refer to long-legged wading Birds such as Storks and Waders, called shorebirds in North America (where "wader" is used to refer to long-legged wading Birds such as Storks and Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. Storks are large long-legged long-necked wading Birds with long stout bills, belonging to the family Ciconiidae. The herons are wading Birds in the Ardeidae family Some are called Egrets or Bitterns instead of herons This article is about the taxonomic rank for the sequence of species in a taxonomic list see Taxonomic order In scientific classification used Charadriiformes is a diverse order of small to medium-large Birds It includes about 350 Species and has members in all parts of the world Seabirds are Birds that have adapted to life within the marine environment The latter are the skuas (Stercorariidae), gulls (Laridae), terns (Sternidae), skimmers (Rhynchopidae), and auks (Alcidae). Skuas are Seabirds in the family Stercorariidae. The three smaller skuas are called jaegers in North America Gulls (often informally Seagulls) are birds in the family Laridae Terns are Seabirds in the family Sternidae, previously considered a subfamily (Sterninae of the gull family Laridae (van Tuinen et al The Skimmers, Rhynchopidae, are a small family of Tern -like Birds in the order Charadriiformes which also includes the Waders Gulls This article is about a family of birds For the American ornithological journal see The Auk. Also, the pratincoles (Glareolidae) and the Crab Plover (Dromadidae), which bear greater resemblance to waders, are closely related to the seabirds. The Pratincoles are a group of Birds which together with the Coursers and Egyptian Plover make up the family Glareolidae. The Crab Plover ( Dromas ardeola is a Bird related to the Waders but sufficiently distinctive to merit its own family Dromadidae.

This leaves about 210 species, most of which are associated with wetland or coastal environments. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Bird migration refers to the regular seasonal journeys undertaken by many species of Birds Bird movements include those made in response to changes in food availability Some of the Arctic species, such Little Stint are amongst the longest distance migrants, spending the non-breeding season in the southern hemisphere. The Little Stint, Calidris or Erolia minuta, is a very small Wader. Southern Hemisphere is the half of a Planet that is South of the Equator —the word hemisphere literally means 'half ball'

The majority of species eat small invertebrates picked out of mud or exposed soil. An invertebrate is an Animal lacking a Vertebral column. The group includes 98% of all animal Species — all animals except those in the Chordate In computer gaming, a MUD ( Multi-User Dungeon, Domain or Dimension) is a multi-player computer game that combines elements of 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. Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Reptiles, or members of the class Reptilia are air-breathing Cold-blooded Vertebrates that have skin covered in scales as opposed to hair or feathers

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 calidrids or typical waders are a group of Arctic -breeding strongly migratory wading Birds These birds form huge mixed flocks

The smallest member of this group is the Least Sandpiper, small adults of which can weigh as little as 15. The Least Sandpiper, Calidris or Erolia minutilla, is the smallest Shorebird. 5 grams and measure just over 13 cm (5 inches). The largest species is believed to be the Far Eastern Curlew, at about 63 cm (25 inches) and 860 grams (1. The Far Eastern Curlew or Eastern Curlew ( Numenius madagascariensis) is a large shorebird most similar in appearance to the Long-billed Curlew 9 lb), although the Beach Thick-knee, is the heaviest at about 1 kg (2. The Beach Stone-curlew, Esacus giganteus also known as Beach Thick-knee is a large ground-dwelling bird occurs in Australasia and the islands 2 lb).

In the Sibley-Ahlquist taxonomy, waders and many other groups are subsumed into a greatly enlarged Ciconiiformes order. The Sibley-Ahlquist taxonomy is a radical bird Taxonomy proposed by Charles Sibley and Jon Edward Ahlquist. Traditionally the order Ciconiiformes has included a variety of large long-legged wading birds with large bills Storks Herons Egrets 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. DNA-DNA hybridization generally refers to a Molecular biology technique that measures the degree of genetic similarity between pools of DNA sequences Formerly, the waders were united in a single suborder Charadrii, but this has turned out to be a "wastebasket taxon", uniting no less than four charadriiform lineages in a paraphyletic assemblage. Wastebasket taxon (also called a wastebin taxon or dustbin taxon) is a term used in taxonomic circles to refer to a Taxon that has the sole purpose In Phylogenetics, a group of organisms is said to be paraphyletic if the group contains its most recent common ancestor but does not contain all However, it indicated that the Plains Wanderer actually belonged into one of them. The Plains Wanderer, Pedionomus torquatus, is a unique Bird and is put in a family of its own 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:

Dunlin (Calidris alpina).
Dunlin (Calidris alpina). The Dunlin, Calidris alpina, is a small Wader, sometimes separated with the other " Stints quot in Erolia.

In keeping more in line with the traditional grouping, the Thinocori could be included in the Scolopaci, and the Chionidi in the Charadrii.

The oystercatchers are a group of Waders they form the family The bird family Charadriidae includes the Plovers Dotterels and Lapwings about 64 to 66 Species in all 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. The Cretaceous–Tertiary extinction event, which occurred approximately ( Ma) was a large-scale mass extinction of animal and plant species in a geologically
