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 polyphyletic. The genus contains three species: The name ''Gavicalis'' was first proposed by the Australian ornithologists Richard Schodde and Ian Mason in 1999. The word is an anagram of ''Caligavis'' introduced by Tom Iredale Tom Iredale (24 March 1880 – 12 April 1972) was an English-born ornithologist and malacologist who had a long association with Australia, where he lived for most of his life.

Mangrove Honeyeater
The mangrove honeyeater (''Gavicalis fasciogularis'') is a species of bird in the honeyeater family 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 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 ( Entomyzon cyanotis), Bell miner ( Manorina melanophrys), Stitchbird ( Notiomystis cincta), Western spinebill ( Acanthorhynchus superciliosus), and the Wattlebirds of the genus Anthochaera.

Singing Honeyeater
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'.

Lichenostomus
''Lichenostomus'' is a genus of honeyeaters 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 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 Greek Greek may refer to: Greece Anything of, from, or related to Greece, a country in Southern Europe: *Greeks, an ethnic group. *Greek language, a branch of the Indo-European language family. **Proto-Greek language, the assumed last common ancestor ...

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.

Polyphyly
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with system ...

Richard Schodde
Richard Schodde, OAM (born 23 September 1936) is an Australian botanist and ornithologist. Schodde studied at the University of Adelaide, where he received a BSc (Hons) in 1960 and a PhD in 1970. During the 1960s he was a botanist with the 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 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 as 15,000 samples of frozen tissue for molecular studies.Bright Sparcs In the 2009 Queen's birthday honours, Schodde was awarded an OAM for his contribution to the natu ...

Mangrove Honeyeater Decept
A mangrove is a shrub or tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are adapted to the low-oxygen conditions of water ...
