21-506: A snipe is any of about 26 wading bird species in three genera in the family Scolopacidae . They are characterized by a very long, slender bill, eyes placed high on the head, and cryptic / camouflaging plumage . The Gallinago snipes have a nearly worldwide distribution, the Lymnocryptes snipe is restricted to Asia and Europe and the Coenocorypha snipes are found only in
42-455: A considerable number of living and extinct bird families , with a widespread geographical diversity. Gruiform means "crane-like". Traditionally, a number of wading and terrestrial bird families that did not seem to belong to any other order were classified together as Gruiformes. These include 15 species of large cranes , about 145 species of smaller crakes and rails , as well as a variety of families comprising one to three species , such as
63-599: A shooter who makes distant shots from concealment. Wading bird Birders in Canada and the United States refer to several families of long-legged wading birds in semi- aquatic ecosystems as waders . These include the families Phoenicopteridae (flamingos) , Ciconiidae (storks) , Threskiornithidae (ibises and spoonbills) , Ardeidae (herons, egrets, and bitterns) , and the extralimital families Scopidae (hamerkop) and Balaenicipitidae (shoebill) of Africa. Elsewhere in
84-407: Is also highly alert and startled easily, rarely staying long in the open. If the snipe flies, hunters have difficulty wing-shooting due to the bird's erratic flight pattern. The difficulties involved around hunting snipes gave rise to the military term sniper , which originally meant an expert hunter highly skilled in marksmanship and camouflaging , but later evolved to mean a sharpshooter or
105-571: Is dependent on the inclusion of one or two specific loci in the analyses. One locus, i.e., mitochondrial DNA , contradicts the strict monophyly of Coronaves (Morgan-Richards et al. 2008), but phylogeny reconstruction based on mitochondrial DNA is complicated by the fact that few families have been studied, the sequences are heavily saturated (with back mutations) at deep levels of divergence, and they are plagued by strong base composition bias. The kagu and sunbittern are one another's closest relatives. It had been proposed (Cracraft 2001) that they and
126-541: The Heliornithidae , the limpkin , or the Psophiidae . Other birds have been placed in this order more out of necessity to place them somewhere ; this has caused the expanded Gruiformes to lack distinctive apomorphies . Recent studies indicate that these "odd Gruiformes" are if at all only loosely related to the cranes, rails, and relatives ("core Gruiformes"). There are only two suprafamilial clades (natural groups) among
147-480: The outlying islands of New Zealand . The four species of painted snipe are not closely related to the typical snipes, and are placed in their own family, the Rostratulidae. Snipes search for invertebrates in the mud with a " sewing-machine " action of their long bills. The sensitivity of the bill is caused by filaments belonging to the fifth pair of nerves, which run almost to the tip and open immediately under
168-462: The Gruiformes based on large DNA–DNA hybridization distances to other supposed Gruiformes. However, it was not until the work of Paton et al. (2004) and Fain and Houde (2004, 2006) that the correct placement of buttonquails within the shorebirds (order Charadriiformes) was documented on the basis of phylogenetic analysis of multiple genetic loci. Using 12S ribosomal DNA sequences, Houde et al. (1997) were
189-445: The Gruiformes, e.g., Ergilornithidae, Phorusrhacidae, Messelornithidae, Eogruidae, Idiornithidae, Bathornithidae, to name just a few (see below). Though some of these are superficially 'crane-like' and the possibility exists that some may even be related to extant families traditionally included in the Gruiformes, there are no completely extinct families that can be confidently assigned to core-Gruiformes. The traditional order Gruiformes
210-768: The birds traditionally classified as Gruiformes. Rails ( Rallidae ), flufftails ( Sarothruridae ), finfoots and sungrebe ( Heliornithidae ), adzebills ( Aptornithidae ), trumpeters ( Psophiidae ), limpkin ( Aramidae ), and cranes ( Gruidae ) compose the suborder Grues and are termed "core-Gruiformes". These are the only true Gruiformes. The suborder Eurypygae includes the kagu (Rhynochetidae) and sunbittern (Eurypygidae). These are not even remotely related to Grues. The families of mesites or roatelos ( Mesitornithidae ), button-quails ( Turnicidae ), Australian plains-wanderer ( Pedionomidae ), seriemas ( Cariamidae ), and bustards ( Otididae ) each represent distinct and unrelated lineages. Many families known only from fossils have been assigned to
231-500: The first to present molecular genetic evidence of gruiform polyphyly , although apparently they were not convinced by it. However, on the basis of numerous additional sequence data, it has been shown decisively that the traditionally recognized Gruiformes consist of five to seven unrelated clades (Fain and Houde 2004, Ericson et al. 2006, Hackett et al. 2008). Fain and Houde (2004) proposed that Neoaves are divisible into two clades, Metaves and Coronaves, although it has been suggested from

#1732851742851252-431: The hamerkop and the shoebill are more closely related to pelicans . As a result of these changes flamingos are placed in their own order Phoenicopteriformes and Ciconiiformes are solely restricted to the storks. The rest of the waders have been reclassified into the order Pelecaniformes . In some field guides, the families Gruidae (cranes) and Aramidae (limpkin) are also considered to be waders too. However unlike
273-455: The previously mentioned families, cranes and the limpkin were never thought to be closely related to the heron-like birds and have always been classified as members of the order Gruiformes . This bird-related article is a stub . You can help Misplaced Pages by expanding it . Gruiformes Some 5–10 living, see article text. The Gruiformes ( / ˈ ɡ r uː ɪ f ɔːr m iː z / GROO -ih-for-meez ) are an order containing
294-792: The recently extinct adzebills (family Aptornithidae) from New Zealand constitute a distinct Gondwanan lineage. However, sunbittern and kagu are believed to have diverged from one another long after the break-up of Gondwanaland and the adzebills are in fact members of the Grues (Houde et al. 1997, Houde 2009). The seriemas and bustards represent distinct lineages within neoavian waterbirds. Psophiidae – trumpeters (3 species) Aramidae – limpkin Gruidae – cranes (15 species) Rallidae – rails, crakes and coots (152 species) Heliornithidae – finfoots (3 species) Sarothruridae – flufftails (15 species) Gruiformes When considered to be monophyletic, it

Snipes feed mainly on insect larva . Other invertebrate prey include snails , crustacea , and worms . The snipe's bill allows
336-528: The start that Metaves may be paraphyletic (Fain and Houde 2004, Ericson et al. 2006, Hackett et al. 2008). Sunbittern, kagu, and mesites all group within Metaves but all the other lineages of "Gruiformes" group either with a collection of waterbirds or landbirds within Coronaves. This division has been upheld by the combined analysis of as many as 30 independent loci (Ericson et al. 2006, Hackett et al. 2008), but
357-499: The traditional Gruiformes. They recognized that the Australian plains-wanderer (family Pedionomidae) was actually a member of the shorebirds (order Charadriiformes) based on skeletal characters. This was confirmed by Sibley and Ahlquist (1990) based on DNA–DNA hybridization and subsequently by Paton et al. (2003), Paton and Baker (2006) and Fain and Houde (2004, 2006). Sibley and Ahlquist furthermore removed button-quails (Turnicidae) from

Snipes can be found in various types of wet marshy settings including bogs , swamps , wet meadows , and along rivers , coast lines, and ponds . Snipes avoid settling in areas with dense vegetation, but rather seek marshy areas with patchy cover to hide from predators. Camouflage may enable snipes to remain undetected by hunters in marshland . The bird
399-444: The world, the word refers to what North Americans call a " shorebird ", various families of the order Charadriiformes . In the past all of these families were classified in the order Ciconiiformes based on overall similarity in anatomy and ecology, as well as some molecular data. However recent genomic studies have found that this group to be polyphyletic , with flamingos being more closely related to grebes while ibises, herons,
420-479: Was assumed that Gruiformes was among the more ancient of avian lineages. The divergence of "gruiforms" among "Metaves" and "Coronaves" is proposed to be the first divergence among Neoaves, far predating the Cretaceous–Paleogene extinction event c. 66 mya (Houde 2009). No unequivocal basal gruiforms are known from the fossil record. However, there are several genera that are not unequivocally assignable to
441-451: Was established by the influential German avian comparative anatomist Max Fürbringer (1888). Over the decades, many ornithologists suggested that members of the order were in fact more closely related to other groups (reviewed by Olson 1985, Sibley and Ahlquist 1990). For example, it was thought that sunbittern might be related to herons and that seriemas might be related to cuckoos. Olson and Steadman (1981) were first to correctly disband any of
