White-streaked Honeyeater
The white-streaked honeyeater (''Trichodere cockerelli'') is a species of bird in the family Meliphagidae. It is monotypic within the genus ''Trichodere''. It is endemic to Cape York Peninsula. Its natural habitat is subtropical or tropical dry forest. John Gould described the white-streaked honeyeater as ''Ptilotis cockerelli'' in 1869, naming it in honour of the person—one Mr Cockerell—who shot the specimen. Gould was unsure of which genus to place it in, noting it had features that linked it to ''Stigmatops'' and ''Meliphaga'' as well, and even contemplated placing it in its own genus. Alfred North erected the genus ''Trichodere'' in 1912, observing that its throat feathers were hairy in appearance, unlike any other honeyeater. The genus name was derived from the Ancient Greek words ''thrix'' 'hair' and ''deirē'' 'throat'. A 2017 genetic study using both mitochondrial and nuclear DNA found the white-streaked honeyeater to lie within the clade of the genus '' Phylidony ...

Alfred John North
Alfred John North (11 June 1855 – 6 May 1917) was an Australian ornithologist. North was born in Melbourne and was educated at Melbourne Grammar School. He was appointed to the Australian Museum, Sydney in 1886 and was given a permanent position there five years later. He wrote a ''List of the Insectivorous Birds of New South Wales'' (1897) and a ''Descriptive Catalogue of the Nests and Eggs of Birds Found Breeding in Australia and Tasmania'' (1889) with George Barnard as co-author. He described a number of birds for the first time, many in the ''Victorian Naturalist'', the magazine of the Field Naturalists Club of Victoria of which he was a founding member.

New Holland Honeyeater
The New Holland honeyeater (''Phylidonyris novaehollandiae'') is a honeyeater species found throughout southern Australia. It was among the first birds to be scientifically described in Australia, and was initially named ''Certhia novaehollandiae''. Taxonomy There are currently five described subspecies of ''Phylidonyris novaehollandiae'': *'' P. novaehollandiae novaehollandiae'' (South-eastern mainland Australia; Latham, 1790) *'' P. novaehollandiae canescens'' (Tasmania; Latham, 1790), *'' P. novaehollandiae campbelli'' (Kangaroo Island, South Australia; Matthews, 1923) *'' P. novaehollandiae longirostris'' (Western Australia; Gould, 1846) *'' P. novaehollandiae caudatus'' (Bass Strait islands; Salomonsen, 1966). Description The bird is around long and is mainly black, with a white iris, white facial tufts and yellow margins on its wing and tail feathers. It is a very active bird and rarely sits long enough to give an extended view. When danger approaches a New Holland honeye ...

Endemic Birds Of Australia
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in birds. Patterns of endemism Family-level endemism is prominent in Australia. The Australasian biogeographic region has the highest number of endemic families of any zoogeographic region except the Neotropics, and many of these families are endemic to Australia itself — the country therefore stakes a strong claim to be the world's greatest hotspot of bird endemism. Australian endemic and near-endemic families The Australian endemic families are: * Emu (Dromaiidae), a well-known monotypic family; the emu is found in rural areas throughout the continent * Plains-wanderer (Pedionomidae), a monotypic family; plains-wanderer is restricted to arid inland areas in the southeast of Australia * Lyrebirds (Menuridae), two forest-dwelling species of southeast Australia * Scrub-birds (Atrichornithidae), two ...

Birds Of Cape York Peninsula
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 swimming. Bird ...

Meliphagoidea
__NOTOC__ Meliphagoidea is a superfamily of passerine birds. They contain a vast diversity of small to mid-sized songbirds widespread in the Austropacific region. The Australian Continent has the largest richness in genera and species. Systematics This group was proposed based on the phenetic DNA-DNA hybridization studies of Charles Sibley ''et al.''. A more modern definition of a monophyletic Meliphagoidea based on cladistic analysis was made by ornithologists at the American Museum of Natural History.Barker, F. Keith; Cibois, Alice; Schikler, Peter A.; Feinstein, Julie & Cracraft, Joel (2004): Phylogeny and diversification of the largest avian radiation. ''PNAS'' 101 (30): 11040–11045.

Maluridae
The Australasian wrens are a family, Maluridae, of small, insectivorous passerine birds endemic to Australia and New Guinea. While commonly known as wrens, they are unrelated to the 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. With further morphological work and the great st ... [...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 ...

Molecule
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and ''molecule'' is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (molecule), water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gases, the term ''molecule'' is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, since the noble gases are individual atoms. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crescent Honeyeater
The crescent honeyeater (''Phylidonyris pyrrhopterus'') is a passerine bird of the honeyeater family Meliphagidae native to southeastern Fauna of Australia, Australia. A member of the genus ''Phylidonyris'', it is most closely related to the common New Holland honeyeater (''P. novaehollandiae'') and the white-cheeked honeyeater (''P. niger''). Two subspecies are recognized, with ''P. p. halmaturinus'' restricted in range to Kangaroo Island and the Mount Lofty Ranges in South Australia. It has dark grey plumage and paler underparts, highlighted by yellow wing-patches and a broad, black crescent, outlined in white, down the sides of its breast. The species exhibits slight sexual dimorphism, with the female being duller in colour than the male. Juvenile birds are similar to the female, though the yellow wing-patches of male nestlings can be easily distinguished. The male has a complex and variable bird vocalization, song, which is heard throughout the year. It sings from an exposed ...

White-cheeked Honeyeater
The white-cheeked honeyeater (''Phylidonyris niger'') inhabits the east coast and the south-west corner of Australia. It has a large white patch on its cheek, brown eyes, and a yellow panel on its wing. Taxonomy The white-cheeked honeyeater was described by Bechstein in 1811. Two subspecies are recognised: ''Phylidonyris niger niger'' in eastern Australia; and ''P. n. gouldii'' (Schlegel, 1872) in southwest Western Australia. The latter subspecies has a narrower white cheek-patch, slightly more black on the breast, and different vocalizations, which in future may lead to its classification as a separate species. The generic name ''Phylidonyris'' combines the term ''Phylidon'' or ''Philedon'', used by the French naturalist Georges Cuvier in 1817 for the friarbirds (now placed in the genus '' Philemon''), with ''Cinnyris'' (Cuvier, 1816) for the sunbirds; the specific epithet derives from Latin ''niger'' 'black'.
