Blue-grey Robin
The slaty robin (''Peneothello cyanus''), also known as the blue-grey robin, is a species of bird in the family Petroicidae, present in the New Guinea Highlands and sparsely in the island's northern areas. Its natural habitat is subtropical or tropical moist montane forests. Described by Italian naturalist, Tommaso Salvadori, in 1874, the slaty robin is a member of the Australasian robin family Petroicidae The bird family Petroicidae includes 51 species in 19 genera. All are endemic to Australasia: New Guinea, Australia, New Zealand and numerous Pacific Islands as far east as Samoa. For want of an accurate common name, the family is often called th ....* Sibley and Ahlquist's DNA-DNA hybridisation studies placed this group in a Corvida parvorder comprising many tropical and Australian passerines including pardalotes, fairy-wrens, honeyeaters, and crows. However, subsequent molecular research (and current consensus) places the robins as a very early offshoot of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tommaso Salvadori
Count Adelardo Tommaso Salvadori Paleotti (30 September 1835 – 9 October 1923) was an Italian zoologist and ornithologist. Biography Salvadori was born in Porto San Giorgio, son of Count Luigi Salvadori and Ethelyn Welby, who was English. His brother Giorgio married their cousin Adele Emiliani (daughter of Giacomo Emiliani and Casson Adelaide Welby) and had five children (Charlie, Robbie, Minnie, Nellie and Guglielmo "Willie"). His nephew Guglielmo Salvadori Paleotti married Giacinta Galletti de Cadilhac (daughter of Arturo Galletti de Cadilhac and Margaret Collier) and had three children (Gladys, Massimo "Max" and Gioconda Beatrice "Joyce"). He studied medicine in Pisa and Rome and graduated in medicine at the University of Pisa. He participated in Garibaldi's military expedition in Sicily (the Expedition of the Thousand), serving as a medical officer. He was assistant in the Museum of Zoology in 1863, becoming Vice-Director of the Royal Museum of Natural History in Tur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvida
The "Corvida" were one of two "parvorders" contained within the suborder Passeri, as proposed in the Sibley-Ahlquist taxonomy, the other being Passerida. Standard taxonomic practice would place them at the rank of infraorder. More recent research suggests that this is not a distinct clade—a group of closest relatives and nothing else—but an evolutionary grade instead. As such, it is abandoned in modern treatments, being replaced by a number of superfamilies that are considered rather basal among the Passeri. It was presumed that cooperative breeding—present in many or most members of the Maluridae, Meliphagidae, Artamidae and Corvidae, among others—is a common apomorphy of this group.Cockburn (1996) But as evidenced by the updated phylogeny, this trait is rather the result of parallel evolution, perhaps because the early Passeri had to compete against many ecologically similar birds (see near passerine).

Peneothello
''Peneothello'' is a genus of passerine birds in the Australasian robin family Petroicidae. The genus ''Peneothello'' was introduced by the Australian born ornithologist Gregory Mathews in 1920 with white-winged robin (''Peneothello sigillata'') as the type species. The name combines the Latin ''pene'' "almost" and ''othello''. Othello is the "Moorish" (i.e. black) Shakespeare character. Species The genus contains the following five 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 ...: References External links * * Petroicidae Bird genera Taxonomy articles created by Polbot {{Petroicidae-stub ...

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Songbird
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. Version 06 February 2013 (under construction). http://tolweb.org/Passeriformes/15868/2013.02.06 in The Tree of Life Web Project, http://tolweb.org/ ccessed 2017/12/11 found all over the world, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song. 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 thos ...

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. Few occur in the Americas, highest diversity of famili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meliphagidae
The honeyeaters are a large and diverse family, Meliphagidae, of small to medium-sized birds. The family includes the Australian chats, myzomelas, friarbirds, wattlebirds, miners and melidectes. They are most common in Australia and New Guinea, and found also in New Zealand, the Pacific islands as far east as Samoa and Tonga, and the islands to the north and west of New Guinea known as Wallacea. Bali, on the other side of the Wallace Line, has a single species. In total there are 186 species in 55 genera, roughly half of them native to Australia, many of the remainder occupying New Guinea. With their closest relatives, the Maluridae (Australian fairy-wrens), Pardalotidae (pardalotes), and Acanthizidae (thornbills, Australian warblers, scrubwrens, etc.), they comprise the superfamily Meliphagoidea and originated early in the evolutionary history of the oscine passerine radiation. Although honeyeaters look and behave very much like other nectar-feeding passerines around the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maluridae
The Australasian wrens are a family (biology), family, Maluridae, of small, insectivorous passerine birds endemic to Australia and New Guinea. While commonly known as wrens, they are unrelated to the wren, true wrens. The family comprises 32 species (including sixteen fairywrens, three emu-wrens, and thirteen grasswrens) in six genera. Taxonomy and systematics As with many other Australian creatures, and perhaps more than most, the species making up this family were comprehensively misunderstood by early researchers. They were variously classified as Old World flycatchers, Old World warblers, and Old World babblers. In the late 1960s morphological studies began to suggest that the Australo-Papuan fairywrens, the grasswrens, emu-wrens and two monotypic wren-like genera from New Guinea were related and, following Charles Sibley's pioneering work on egg-white proteins in the mid-1970s, Australian researchers adopted the family name Maluridae in 1975.

Parvorder
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
