Suboscine
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 * Calyptomeni ...

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 passeri ...

Sapayoa
The sapayoa or broad-billed sapayoa (''Sapayoa aenigma'') is a suboscine passerine found in lowland rainforests in Panama and north-western South America. As the epithet ''aenigma'' ("the enigma") implies, its relationships have long been elusive. It is easy to overlook, but appears to be common in a wide range and is not considered threatened by the IUCN. Taxonomy and systematics The sapayoa was formally described by the German ornithologist Ernst Hartert in 1903 under the present binomial name ''Sapayoa aenigma''. It has always been considered a monotypic genus, ''Sapayoa'', and historically regarded as a New World suboscine; in particular, it was assigned to the manakin family (Pipridae). However, the species was listed as ''incertae sedis'' (position uncertain) in the Sibley-Ahlquist taxonomy, because "preliminary DNA-DNA hybridization comparisons ... indicate that this species is either a relative of the Old World Eurylaimidae or a sister group of all other Tyrannida, as ...

Pitta
Pittas are a family, Pittidae, of passerine birds found in Asia, Australasia and Africa. There are thought to be 40 to 42 species of pittas, all similar in general appearance and habits. The pittas are Old World suboscines, and their closest relatives among other birds are in the genera ''Smithornis '' and ''Calyptomena''. Initially placed in a single genus, as of 2009 they have been split into three genera: ''Pitta'', ''Erythropitta'' and ''Hydrornis''. Pittas are medium-sized by passerine standards, at in length, and stocky, with strong, longish legs and long feet. They have very short tails and stout, slightly decurved bills. Many have brightly coloured plumage. Most pitta species are tropical; a few species can be found in temperate climates. They are mostly found in forests, but some live in scrub and mangroves. They are highly terrestrial and mostly solitary, and usually forage on wet forest floors in areas with good ground cover. They eat earthworms, snails, insects a ...

Acanthisittidae
The New Zealand wrens are a family (Acanthisittidae) of tiny passerines endemic to New Zealand. They were represented by seven Holocene species in four or five genera, although only two species in two genera survive today. They are understood to form a distinct lineage within the passerines, but authorities differ on their assignment to the oscines or suboscines (the two suborders that between them make up the Passeriformes). More recent studies suggest that they form a third, most ancient, suborder Acanthisitti and have no living close relatives at all. They are called "wrens" due to similarities in appearance and behaviour to the true wrens (Troglodytidae) but are not members of that family. New Zealand wrens are mostly insectivorous foragers of New Zealand's forests, with one species, the New Zealand rock wren, being restricted to alpine areas. Both the remaining species are poor fliers and four of the five extinct species are known or suspected to have been flightless. Along w ...

Eurylaimidae
The Eurylaimidae are a family of suboscine passerine birds that occur from the eastern Himalayas to Indonesia and the Philippines. The family previously included the sapayoa from the Neotropics, the asities from Madagascar, and the Calyptomenidae from Africa and Asia, but these are now separated into distinct families. Description Many of the species are brightly coloured birds that present broad heads, large eyes and a hooked, flat and broad beak. They range from 13 to 28 centimetres in length, and live in the dense canopies of wet forests, allowing them to hide despite their brightly coloured plumage. The plumage of the juvenile eurylaimids are similar to those of the adults, differing in being duller and shorter-winged and shorter-tailed in some cases. Behaviour and ecology They are for the most part insectivorous and carnivorous. Prey taken includes insects, spiders, centipedes, and millipedes, as well as lizards and tree frogs. Prey is obtained by sallying from a perch to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syrinx (biology)
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 syrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeographical
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.Brown University, "Biogeography." Accessed February 24, 2014. . Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.Dansereau, Pierre. 1957.

Americas
The Americas, which are sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon, St. Lawrence River–Great Lakes basin, Mississippi, and La Plata. Since the Americas extend from north to south, the climate and ecology vary widely, from the arctic tundra of Northern Canada, Greenland, and Alaska, to the tropical rain forests in Central America and South America. Humans first settled the Americas from Asia between 42,000 and 17,000 years ago. A second migration of Na-Dene speakers followed later ...
