Gymnoris
''Gymnoris'' is a genus of passerine birds in the sparrow family Passeridae. Three species are found in Africa while the yellow-throated sparrow ranges from Turkey to India. The genus was introduced by the English zoologist Edward Blyth in 1845 with the yellow-throated sparrow as the type species. The name combines the Ancient Greek words ''gumnos'' "bare" or "naked" and ''rhinos'' "nostrils". Species There are four species recognized: These species are sometimes placed in the genus ''Petronia''.

Yellow-throated Sparrow
The yellow-throated sparrow or chestnut-shouldered petronia (''Gymnoris xanthocollis'') is a species of sparrow found in southern Asia. It is a species mostly of the dry savannah. They forage on the ground for grain and for berries in bushes. They are often seen perched atop bare branches on trees while calling. Description It has a finer bill than typical sparrows of the genus '' Passer'' and unlike them has no streaks on the plumage. The white double wing bar on the shoulder is diagnostic on the otherwise dull grey-brown sparrow. Males have a chestnut shoulder patch which can sometimes be hard to see. They also have a pale yellow spot on the throat in fresh plumage. Females are duller and lack the chestnut shoulder patch. The yellow spot is much reduced or lacking in females. This species is tree-loving although sometimes seen on wires and on the ground, where it has a hopping gait. The usual call is a ''chirrup'' but the song is distinctive and repetitive '. It has a bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passeridae
Old World sparrows are a group of small passerine birds forming the family Passeridae. They are also known as true sparrows, a name also used for a particular genus of the family, '' Passer''. They are distinct from both the New World sparrows, in the family Passerellidae, and from a few other birds sharing their name, such as the Java sparrow of the family Estrildidae. Many species nest on buildings and the house and Eurasian tree sparrows, in particular, inhabit cities in large numbers. They are primarily seed-eaters, though they also consume small insects. Some species scavenge for food around cities and, like pigeons or gulls, will eat small quantities of a diversity of items. Description Generally, Old World sparrows are small, plump, brown and grey birds with short tails and stubby, powerful beaks. The differences between sparrow species can be subtle. Members of this family range in size from the chestnut sparrow (''Passer eminibey''), at and , to the parrot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gymnoris Dentata
The Sahel bush sparrow (''Gymnoris dentata'') or bush petronia, is a species of bird in the family Passeridae. It is found in Africa from Mauritania to Guinea and east to Eritrea and the south-western Arabian Peninsula in its natural habitats of dry savanna and subtropical or tropical dry shrubland. Description The Sahel bush sparrow is a small bird with a large, conical beak and a short tail. It grows to a length of about . The male has a grey crown, a wide but ill-defined reddish-brown supercilium and greyish-brown face and throat, surrounding the creamy-white bib. The male's beak is black during the breeding season but horn-coloured during the rest of the year. The plumage on the upper parts and tail is mainly brown, with no white on the tail. The upper throat has an ill-defined yellowish spot and the breast is creamy-buff, becoming whiter on the belly. The female is similar, but has a better-defined white supercilium, brownish rather than grey crown and face, horn-coloured ...

Petronia
The rock sparrow or rock petronia (''Petronia petronia'') is a small passerine bird in the sparrow family Passeridae. It is the only member of the genus ''Petronia''. It breeds on barren rocky hills from the Iberian Peninsula and western north Africa across southern Europe and through the Palearctic Siberia and north and central China. It is largely resident in the west of its range, but Asian birds bird migration, migrate to more southerly areas, or move down the mountains. Taxonomy The first Species description, formal description of the rock sparrow was by the Swedish naturalist Carl Linnaeus in 1766 in the 12th edition of Systema Naturae, twelfth edition of his ''Systema Naturae''. He introduced the binomial nomenclature, binomial name ''Fringilla petronia''. It is now the only species in the genus ''Petronia'' that was introduced by the German naturalist Johann Jakob Kaup in 1829. ''Petronia'' is a local name for the rock sparrow from the Bologna area of Italy. Seven subsp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Blyth
Edward Blyth (23 December 1810 – 27 December 1873) was an English zoologist who worked for most of his life in India as a curator of zoology at the Asiatic Society, Royal Asiatic Society of Bengal in Calcutta. He set about updating the museum's catalogues, publishing a ''Catalogue of the Birds of the Asiatic Society'' in 1849. He was prevented from doing much fieldwork himself, but received and described bird specimens from Allan Octavian Hume, A.O. Hume, Samuel Tickell, Robert Swinhoe among others. His ''Natural History of the Cranes'' was published posthumously in 1881. Early life and work On 23 December 1810, Blyth was born in London. His father, a cloth merchant, clothier, died in 1820 and his mother sent him to Dr. Fennell's school in Wimbledon, London, Wimbledon. He took an interest in reading, but was often to be found spending time in the woods nearby. Leaving school in 1825, he went to study chemistry, at the suggestion of Dr. Fennell, in London under Dr. Keating at S ... [...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 ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three suborders: New Zealand wrens; Suboscines, primarily found in North and South America; and songbirds. Passerines originated in the ...
