White-naped Tit
The white-naped tit (''Machlolophus nuchalis''), sometimes called white-winged tit, is a passerine bird in the tit family Paridae. It is endemic to India where it is found in dry thorn scrub forest in two disjunct populations, in western India and southern India. Its specific name ''nuchalis'' means ‘of the nuchal, nape’. This species is hard to mistake with its contrasting black and white patterns without the grey wing coverts and back of the partly sympatric cinereous tit (''Parus cinereus''). This species is very patchily distributed and has been considered to be vulnerable to extinction especially because of the scarcity of suitable habitats particularly nest cavities made by woodpeckers. Taxonomy The white-naped tit was formerly one of the many species in the genus ''Parus'' but was moved to ''Machlolophus'' after a molecular phylogenetic analysis published in 2013 showed that the members of the new genus formed a distinct clade.

Prosopis Juliflora
''Prosopis juliflora'' ( es, bayahonda blanca, Cuji Venezuela, Trupillo Colombia, Aippia Wayuunaiki and long-thorn kiawe in Hawaii) is a shrub or small tree in the family Fabaceae, a kind of mesquite. It is native to Mexico, South America and the Caribbean. It has become established as an invasive weed in Africa, Asia, Australia and elsewhere. It is a contributing factor to continuing transmission of malaria, especially during dry periods when sugar sources from native plants are largely unavailable to mosquitoes. Description Growing to a height of up to , ''P. juliflora'' has a trunk diameter of up to . Its leaves are deciduous, geminate-pinnate, light green, with 12 to 20 leaflets. Flowers appear shortly after leaf development. The flowers are in long green-yellow cylindrical spikes, which occur in clusters of 2 to 5 at the ends of branches. Pods are long and contain between 10 and 30 seeds per pod. A mature plant can produce hundreds of thousands of seeds. See ...

Machlolophus Aplonotus
The Indian black-lored tit, Indian tit, or Indian yellow tit (Grimmett ''et al.'', 2011) (''Machlolophus aplonotus'') is a passerine bird in the tit family Paridae. The yellow-cheeked tit is probably its closest relative, and both may be related to the yellow tit. These three tits almost certainly form a distinct lineage as evidenced by morphology, and mtDNA cytochrome ''b'' sequence analysis (Gill ''et al.'', 2005). The subgenus name ''Macholophus'' may apply for them. This species is a resident breeder on the Indian subcontinent. It is a common bird in open tropical forests, but does not occur in Sri Lanka. It is an active and agile feeder, taking insects and spiders from the canopy, and sometimes fruit. It is an easy tit to recognise in most of India, large in size at 13 cm, with a broad black line (broader in the male) down its otherwise yellow front. The large crest, neck, throat and head are black with yellow cheeks and supercilia. Upperparts are olive-green. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biligirirangan Hills
The Biligirirangana Hills or Biligirirangan Hills (as referred to in biology and geology) is a hill range situated in south-western Karnataka, at its border with Tamil Nadu (Erode District) in South India. The area is called Biligiri Ranganatha Swamy Temple Wildlife Sanctuary or simply BRT Wildlife Sanctuary. It is a protected reserve under the Wildlife Protection Act of 1972. Being close to the Eastern Ghats as well as the Western Ghats, the sanctuary has floral and faunal associations with both regions. The site was declared a tiger reserve in January 2011 by the Karnataka government, a few months after approval from India's National Tiger Conservation Authority. Location The hills are located at the north-west of the Western Ghats and the westernmost edge of the Eastern Ghats. Thus this area supports a diverse flora and fauna in view of the various habitat types present. A wildlife sanctuary of was created around the temple on 27 June 1974, and enlarged to on 14 January 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salim Ali (ornithologist)
Sálim Moizuddin Abdul Ali (12 November 1896 – 20 June 1987) was an Indian ornithologist and naturalist. Sometimes referred to as the "''Birdman of India''", Salim Ali was the first Indian to conduct systematic bird surveys across India and wrote several bird books that popularized ornithology in India. He became a key figure behind the Bombay Natural History Society after 1947 and used his personal influence to garner government support for the organisation, create the Bharatpur bird sanctuary (Keoladeo National Park) and prevent the destruction of what is now the Silent Valley National Park. Along with Sidney Dillon Ripley he wrote the landmark ten volume '' Handbook of the Birds of India and Pakistan'', a second edition of which was completed after his death. He was awarded the Padma Bhushan in 1958 and the Padma Vibhushan in 1976, India's third and second highest civilian honours respectively. Several species of birds, Salim Ali's fruit bat, a couple of bird sanctua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allan Octavian Hume
Allan Octavian Hume, CB ICS (4 June 1829 – 31 July 1912) was a British civil servant, political reformer, ornithologist and botanist who worked in British India. He was the founder of the Indian National Congress. A notable ornithologist, Hume has been called "the Father of Indian Ornithology" and, by those who found him dogmatic, "the Pope of Indian Ornithology". As an administrator of Etawah, he saw the Indian Rebellion of 1857 as a result of misgovernance and made great efforts to improve the lives of the common people. The district of Etawah was among the first to be returned to normalcy and over the next few years Hume's reforms led to the district being considered a model of development. Hume rose in the ranks of the Indian Civil Service but like his father Joseph Hume, a radical member of parliament, he was bold and outspoken in questioning British policies in India. He rose in 1871 to the position of secretary to the Department of Revenue, Agriculture, and Commerce und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nellore
Nellore is a city located on the banks of Penna River, in Nellore district of the Indian state of Andhra Pradesh. It serves as the headquarters of the district, as well as Nellore mandal and Nellore revenue division. It is the List of cities in Andhra Pradesh, fourth most populous city in the state. It is at a distance of 700 km from Visakhapatnam and about 170 km north of Chennai, Tamil Nadu and also about 380 km east-northeast of Bangalore, Karnataka. Etymology There are various theories linked to the origin of the name "Nellore". A mythological story from Sthala Purana depicts, a lingam in the form of a stone under ''Phyllanthus emblica, nelli tree'' ("''Nelli''" stands for ''emblica Tree'' in Tamil). The place gradually became ''Nelli-ooru'' (''ooru'' generally stands for place in Telugu) and then to present day ''Nellore''. Another explanation is that the town got its name from the extensive cultivation of paddy in and around it (''"Nell"'' meaning ''paddy' ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

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.

Machlolophus
''Machlolophus'' is a genus of birds in the tit family. The species were formerly placed with many others in the genus ''Parus'' but were moved to ''Machlolophus'' based on a molecular phylogenetic analysis published in 2013 that showed that the members formed a distinct clade. The name ''Machlolophus'' was introduced by the German ornithologist Jean Cabanis Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. Cabanis was born in Berlin to an old Huguenot family who had moved from France. Little is known of his early life. He studied at the University of Berlin from 1 ... in 1850. The word is derived from the classical Greek ''makhlos'' meaning luxuriant and ''lophos'' meaning crest. The following species, all from Asia, have been placed in the genus: References Bird genera {{Paridae-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parus
''Parus'' is a genus of Old World birds in the tit family. It was formerly a large genus containing most of the 50 odd species in the family Paridae. The genus was split into several resurrected genera following the publication of a detailed molecular phylogenetic analysis in 2013. The genus name, ''Parus'', is the Latin for "tit". Taxonomy The genus ''Parus'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is Latin for "tit". Of the 12 species included in the genus by Linnaeus, the type species was designated as the great tit (''Parus major'') by George Robert Gray in 1840. Species The genus now contains the following species: Fossil record *''Parus robustus'' (Pliocene of Csarnota, Hungary) Kessler, E. 2013. Neogene songbirds (Aves, Passeriformes) from Hungary. – Hantkeniana, Budapest, 2013, 8: 37-149. *''Parus parvulus'' (Pliocene of Csarnota, Hungary) *''Parus medius'' (Pliocene of Berem ...

Cyanistes
''Cyanistes'' is a genus of birds in the tit family Paridae. The genus was at one time considered as a subgenus of Parus. In 2005 an article describing a molecular phylogenetic study that had examined mitochondrial DNA sequences from members of the tit family, proposed that a number of subgenera including ''Cyanistes'' be elevated to genus status. This proposal was accepted by the International Ornithologists' Union and the British Ornithologists' Union. Species The genus contains three species: The name ''Cyanistes'' was introduced for a subgenus by the German naturalist Jakob Kaup in 1829. The word comes from the classical Greek ''kuanos'' meaning dark-blue. The type species was designated as the Eurasian blue tit The Eurasian blue tit (''Cyanistes caeruleus'') is a small passerine bird in the tit family, Paridae. It is easily recognisable by its blue and yellow plumage and small size. Eurasian blue tits, usually resident and non-migratory birds, are ... by Ge ...
