Gavicalis
''Gavicalis'' is a genus of honeyeaters endemic to New Guinea and Australia. It contains former members of ''Lichenostomus'', and was created after a molecular phylogenetic analysis published in 2011 showed that the original genus was polyphyly, polyphyletic. The genus contains three species: The name ''Gavicalis'' was first proposed by the Australian ornithologists Richard Schodde and Ian J. Mason, Ian Mason in 1999. The word is an anagram of ''Caligavis'' introduced by Tom Iredale. References Gavicalis, Bird genera {{Meliphagidae-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove Honeyeater
The mangrove honeyeater (''Gavicalis fasciogularis'') is a species of bird in the honeyeater family Honeyeater, Meliphagidae. The species was once considered to be conspecific with the varied honeyeater, but it is now treated as a separate species. These two species form a genus with the singing honeyeater. It is Endemism, endemic to Australia, where it is restricted to the eastern coast from Townsville in Queensland to northern New South Wales. The species has been expanding its range southward in recent years. The mangrove honeyeater is generally locally common over most of its range, but is rarer in the south. There are 177 species of honeyeaters in 40 genera, including the Blue-faced honeyeater (Blue-faced honeyeater, Entomyzon cyanotis), Bell miner (Bell miner, Manorina melanophrys), Stitchbird (Stitchbird, Notiomystis cincta), Western spinebill (Western spinebill, Acanthorhynchus superciliosus), and the Anthochaera, Wattlebirds of the genus Anthochaera.

Varied Honeyeater (Gavicalis Versicolor) (31359494696)
The varied honeyeater (''Gavicalis versicolor'') is a species of bird in the family Meliphagidae. It is found in coastal areas of New Guinea and eastern Cape York Peninsula in Queensland, Australia. Its natural habitat is subtropical or tropical mangrove forests. The varied honeyeater was previously placed in the genus ''Lichenostomus'', but was moved to '' Gavicalis'' after molecular phylogenetic analysis, published in 2011, showed that the original genus was polyphyletic A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies .... Subspecies The varied honeyeater has two accepted subspecies which are distributed as follows: ''G. v. sonoroides'' - Raja Ampat Island (northwest of New Guinea), Yapen (Geelvink Bay island, northwest New Guinea), coastal New Guinea (except southwest) thro ...

Singing Honeyeater (Gavicalis Virescens) (8079661576)
The singing honeyeater (''Gavicalis virescens'') is a small bird found in Australia, and is part of the honeyeater family Meliphagidae. The bird lives in a wide range of shrubland, woodland, and coastal habitat. It is relatively common and is widespread right across Australia west of the Great Dividing Range, through to the west coast and on Western Australian coastal islands. It does not occur in other countries. Taxonomy The singing honeyeater was originally described as ''Meliphaga virescens lipferti''. It was previously placed in the genus ''Lichenostomus'', but was moved to '' Gavicalis'' after a molecular phylogenetic analysis, published in 2011, showed that the original genus was polyphyletic. The generic name is formed from an anagram of the sister genus ''Caligavis''; the specific epithet is the Latin ''virescens'' meaning 'greenish'. Description Singing honeyeaters can vary in length from . Their overall appearance is grey-brown. The tail and wings are olive-green with ...

Lichenostomus
''Lichenostomus'' is a genus of honeyeaters Endemism, endemic to Australia. The genus formerly contained twenty species but it was split after a molecular phylogenetic analysis published in 2011 showed that the genus was polyphyly, polyphyletic. Former members were moved to the six new genera: ''Nesoptilotis'', ''Bolemoreus'', ''Caligavis'', ''Stomiopera'', ''Gavicalis'' and ''Ptilotula''. The genus contains two species: The name ''Lichenostomus'' was introduced by the German ornithologist Jean Cabanis in 1851. The word is derived from the Ancient Greek, Greek ''leikhēn'' meaning lichen or callous and ''stoma'' meaning mouth. Feeding Both species feed primarily on nectar but also glean insects from foliage and bark and make aerial sallies for invertebrates. The purple-gaped honeyeater can forage in small groups of up to 30 birds. References Lichenostomus, Bird genera Endemic birds of Australia, {{Meliphagidae-stub ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Richard Schodde
Richard Schodde, Order of Australia, OAM (born 23 September 1936) is an Australian botany, botanist and ornithology, ornithologist. Schodde studied at the University of Adelaide, where he received a Bachelor of Science, BSc (Hons) in 1960 and a Doctor of Philosophy, PhD in 1970. During the 1960s he was a botanist with the Commonwealth Scientific and Industrial Research Organisation, CSIRO Division of Land Research and Regional Survey in Papua New Guinea. From 1970 to 1998 he was the foundation curator and director of the Australian National Wildlife Collection (ANWC) in the CSIRO Division of Wildlife and Ecology, following which he became a research fellow there. During this time he led the flora and fauna surveys that helped establish Kakadu National Park and the designation of the Wet Tropics of Queensland, wet tropics of north-eastern Queensland as Australia's first World Heritage Site. These surveys resulted in the accession of almost 50,000 specimens to the ANWC, as well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeyeater
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 aroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
