Songbirds
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

Songbirds form one of the two major lineages of extant perching birds (~4000 species), the other being the Tyranni (~1000 species), which are most diverse in the Neotropics and absent from many parts of the world. The Tyranni have a simpler syrinx musculature, and while their vocalizations are often just as complex and striking as th ...

Bird Song
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the " winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the repetitive and transformative p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passe ...

Syrinx (bird Anatomy)
The syrinx (from the Greek word "σύριγξ" for ''pan pipes'') is the vocal organ of birds. Located at the base of a bird's trachea, it produces sounds without the vocal folds of mammals. The sound is produced by vibrations of some or all of the ''membrana tympaniformis'' (the walls of the syrinx) and the '' pessulus'', caused by air flowing through the syrinx. This sets up a self-oscillating system that modulates the airflow creating the sound. The muscles modulate the sound shape by changing the tension of the membranes and the bronchial openings. The syrinx enables some species of birds (such as parrots, crows, and mynas) to mimic human speech. Unlike the larynx in mammals, the syrinx is located where the trachea forks into the lungs. Thus, lateralization is possible, with muscles on the left and right branch modulating vibrations independently so that some songbirds can produce more than one sound at a time. Some species of birds, such as New World vultures, lack a sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passerida
Passerida is, under the Sibley-Ahlquist taxonomy, one of two parvorders contained within the suborder Passeri (standard taxonomic practice would place them at the rank of infraorder). While more recent research suggests that its sister parvorder, Corvida, is not a monophyletic grouping, the Passerida as a distinct clade are widely accepted. Systematics and phylogeny The Passerida quite certainly consist of the 3 ''major'' subclades outlined by Sibley & Ahlquist (1990). However, their content has been much revised. In addition, it has turned out that not all passeridan lineages neatly fit into this arrangement. The kinglets are so distinct that they might actually form a separate infraorder, as they are only slightly less basal than the Corvoidea or the Picathartidae. See Jønsson & Fjeldså (2006) for details on phylogeny. Superfamily Sylvioidea Mostly smallish insectivores, distribution centered on the Indo-Pacific region.

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melanocharitidae
The Melanocharitidae, the berrypeckers and longbills, is a small bird family restricted to the forests of New Guinea. The family contains eleven species in four (sometimes three) genera. They are small songbirds with generally dull plumage but a range of body shapes. Taxonomy and systematics The identification of the family Melanocharitidae was not known or suspected until the work of Sibley and Ahlquist on the taxonomy of birds using DNA–DNA hybridization The genera had been instead placed with other families. The two genera of berrypecker had been placed inside the flowerpecker family Dicaeidae, and the longbills were once considered to be honeyeaters (which they closely resemble). Sibley and Ahlquist placed the berrypeckers and longbill family close to the painted berrypeckers (Paramythiidae), sunbirds and flowerpeckers, but a 2002 study found them closer to the satinbirds ( Cnemophilidae, a recent split from the birds-of-paradise). It comprises ten species in four genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climacteridae
There are seven species of Australasian treecreeper in the passerine bird family Climacteridae. They are medium-small, mostly brown birds with patterning on their underparts, and all are endemic to Australia-New Guinea. They resemble, but are not closely related to, the Holarctic treecreepers. The family is one of several families identified by DNA–DNA hybridisation studies to be part of the Australo-Papuan songbird radiation. There is some molecular support for suggesting that their closest relatives are the large lyrebirds. As their name implies, treecreepers forage for insects and other small creatures living on and under the bark of trees, mostly eucalypts, though several species also hunt on the ground, through leaf-litter, and on fallen timber. Unlike the Holarctic treecreepers they do not use their tail for support when climbing tree trunks, only their feet. Australasian treecreepers nest in holes in trees. The species in the family hold breeding territories, althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyranni
The Tyranni (suboscines) are a suborder of passerine birds that includes more than 1,000 species, the large majority of which are South American. It is named after the type genus '' Tyrannus''. These have a different anatomy of the syrinx musculature than the oscines (songbirds of the larger suborder Passeri), hence the common name of ''suboscines''. The available morphological, DNA sequence, and biogeographical data, as well as the (scant) fossil record, agree that these two major passerine suborders are evolutionarily distinct clades. Systematics The suborder Tyranni is divided into two infraorders: the Eurylaimides and the Tyrannides. The New Zealand wrens in the family Acanthisittidae are placed in a separate suborder Acanthisitti. The Eurylaimides contain the Old World suboscines – mainly distributed in tropical regions around the Indian Ocean – and a single American species, the sapayoa: * Philepittidae: asities * Eurylaimidae: typical broadbills * Calyptome ...

Callaeidae
Callaeidae (sometimes Callaeatidae) is a family of passerine birds endemic to New Zealand. It contains three genera, with five species in the family. One species, the huia, became extinct early in the 20th century, while the South Island kokako is critically endangered and may be extinct. Although sometimes known as ''wattled crows'', they are not corvids and are only distantly related to crows - ''New Zealand wattlebirds'' is the informal name for this family used by the scientific community.Higgins, P.J. & J.M. Peter (eds) 2002. Handbook of Australian, New Zealand and Antarctic Birds. Volume 6: Pardalotes to Shrike-thrushes. Oxford University Press, Melbourne. Biology and evolution They are ground-dwelling songbirds, 26–38 cm in length. They inhabit dense forests, where they feed on insects. They have strong legs and featherless wattles behind the bill. Their wings are rounded and unusually weak, giving them very limited powers of flight. They are monogamous and main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthizidae
The Acanthizidae—known as Australian warblers—are a family of passerine birds which includes gerygones, the thornbills ''Acanthiza'', and the scrubwrens of ''Sericornis''. The Acanthizidae family consists of small to medium passerine birds, with a total length varying between . They have short rounded wings, slender bills, long legs, and a short tail. Most species have olive, grey, or brown plumage, although some have patches of a brighter yellow. The weebill is the smallest species of acanthizid, and the smallest Australian passerine; the largest is the pilotbird. Taxonomy and systematics Following the Sibley-Ahlquist taxonomy (1990) they were previously regarded as subfamily Acanthizinae within the family Pardalotidae. More recent molecular genetic studies do not support this arrangement. The Dasyornithidae (which include the bristlebirds) are variously seen either as subfamily Dasyornithinae within the family Acanthizidae or Pardalotidae or as own family (Schodde & Maso ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjug ...

Neotropics
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
