Sub-oscine
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 * Calyptomenidae: Af ...

Dusky-capped Flycatcher
The dusky-capped flycatcher (''Myiarchus tuberculifer'') is a passerine bird in the tyrant flycatcher family. It breeds in forest and other woodland from southern Arizona, as well as the Chisos Mountains, Texas, south to northern Argentina and on Trinidad. It is resident in most of its range, but American breeders retreat to Mexico in winter. Adult dusky-capped flycatchers are long and weigh . The upperparts are brown, with a blackish head and short crest. The breast is grey and the belly is bright yellow. The brown tail feathers and wings have paler outer webs. The sexes are similar, but young birds have rufous edgings to the wings and tail. The dusky-capped flycatcher is best separated from other confusingly similar ''Myiarchus'' species by its smaller size, blackish head, and its call, a sorrowful, descending, whistled ' or ''wheeeeeu''. This species is insectivorous and catches its prey by flycatching amongst the middle branches of trees. Fruits such as from gumbo-limbo (' ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

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 ...

Sapayoidae
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 ...

Calyptomenidae
Calyptomenidae is a family of passerine birds found in Africa, the Malay Peninsula and Borneo. There are six species in two genera. The species in this family were formerly included in the broadbill family 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 Calyptomeni .... A molecular phylogenetic study published in 2006 found that the species in these two genera were not closely related to the other broadbills. These two genera are now placed in a separate family.

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] |
Philepittidae
The asities are a family of birds, Philepittidae, that are endemic to Madagascar. The asities consist of four species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ... in two genus, genera.

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 ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised.

Old World
The "Old World" is a term for Afro-Eurasia that originated in Europe , after Europeans became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia, which were previously thought of by their inhabitants as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and they have a p ...

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 ...
