Sturnus Pagodarum
The brahminy myna or brahminy starling (''Sturnia pagodarum)'' is a member of the starling family of birds. It is usually seen in pairs or small flocks in open habitats on the plains of the Indian subcontinent. Description This myna is pale buff creamy with a black cap and a loose crest. The bill is yellow with a bluish base. The iris is pale and there is a bluish patch of skin around the eye. The outer tail feathers have white and the black primaries of the wings do not have any white patches. The adult male has a more prominent crest than the female and also has longer neck hackles. Juveniles are duller and the cap is browner. The species name ''pagodarum'' is thought to be based on occurrence of the species on buildings and temple pagodas in southern India. Distribution and habitat It is a resident breeder in Nepal and India, a winter visitor to Sri Lanka and a summer visitor in parts of the western and northeastern Himalayas. They are spotted in the plains of Pakistan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rajasthan
Rajasthan (; lit. 'Land of Kings') is a state in northern India. It covers or 10.4 per cent of India's total geographical area. It is the largest Indian state by area and the seventh largest by population. It is on India's northwestern side, where it comprises most of the wide and inhospitable Thar Desert (also known as the Great Indian Desert) and shares a border with the Pakistani provinces of Punjab to the northwest and Sindh to the west, along the Sutlej- Indus River valley. It is bordered by five other Indian states: Punjab to the north; Haryana and Uttar Pradesh to the northeast; Madhya Pradesh to the southeast; and Gujarat to the southwest.

Thevetia Peruviana
''Cascabela thevetia'' (syn: ''Thevetia peruviana'') is a poisonous plant native throughout Mexico and in Central America, and cultivated widely as an ornamental. It is a relative of ''Nerium oleander'', giving it a common name yellow oleander, and is also called lucky nut in the West Indies. Etymology 'Cascabel', 'cascavel' or 'cascabela' is Spanish for a small bell, a snake's rattle or a rattlesnake itself. The allusion may also be to the plant's toxicity comparable to the venom of a rattlesnake. The latin specific name ''thevetia'' commemorates André de Thevet (1516-1590), a French Franciscan priest and explorer, who explored Brazil and Guiana (where the plant is known as chapéu-de-napoleão, ie, Napoleon's hat). Description ''Cascabela thevetia'' is an evergreen tropical shrub or small tree. Its leaves are willow-like, linear-lanceolate, and glossy green in color. They are covered in waxy coating to reduce water loss (typical of oleanders). Its stem is green turning silve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of South Asia
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. Bi ...

Starlings
Starlings are small to medium-sized passerine birds in the family Sturnidae. The Sturnidae are named for the genus ''Sturnus'', which in turn comes from the Latin word for starling, ''sturnus''. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for habitats with native birds and are considered to be invasive species. The starling species familiar to most people in Europe and North America is the common starling, and throughout much of Asia and the Pacific, the common myna is indeed common. Starlings have strong feet, their flight is strong and direct, and they are very gregarious. Their preferred habit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sturnia
''Sturnia'' is a genus of Asian birds in the family Sturnidae. It is sometimes merged with ''Sturnus''.Clements, J. (2007). ''The Clements Checklist of the Birds of the World.'' 6th edition. Christopher Helm. Species The old genus' placement with the starlings was found to be polyphyletic, resulting in changes in the placement. A 2008 study places the following species within this genus:Zuccon, D., Pasquet, E. & Ericson, P. G. P. (2008).

Polyphyletic
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 systema ...

Erythrina
''Erythrina'' is a genus of plants in the pea family, Fabaceae. It contains about 130 species, which are distributed in tropical and subtropical regions worldwide. They are trees, with the larger species growing up to in height. The generic name is derived from the Greek word , meaning "red", referring to the flower color of certain species. Names Particularly in horticulture, the name coral tree is used as a collective term for these plants. Flame tree is another vernacular name, but may refer to a number of unrelated plants as well. Many species of ''Erythrina'' have bright red flowers, and this may be the origin of the common name. However, the growth of the branches can resemble the shape of sea coral rather than the color of ''Corallium rubrum'' specifically, and this is an alternative source for the name. Other popular names, usually local and particular to distinct species, liken the flowers' red hues to those of a male chicken's wattles, and/or the flower shape to i ...

Butea Monosperma
''Butea monosperma'' is a species of '' Butea'' native to tropical and sub-tropical parts of the South Asia and Southeast Asia, ranging across Pakistan, India, Bangladesh, Nepal, Sri Lanka, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, and western Indonesia. Common names include flame-of-the-forest, palash, and bastard teak. Revered as sacred by Hindus, it's prized for producing an abundance of vivid blooms, but it's also cultivated elsewhere as an ornamental. ''Butea monosperma'', which grows slowly, creates a stunning specimen tree. Description It is a small-sized dry-season deciduous tree, growing to tall. It is a slow-growing tree: young trees have a growth rate of a few feet per year. The leaves are pinnate, with an petiole and three leaflets, each leaflet long. The flowers are long, bright orange-red, and produced in racemes up to long. The fruit is a pod long and broad.Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . Flowers ...

Grey-headed Myna
The chestnut-tailed starling (''Sturnia malabarica''), also called grey-headed starling and grey-headed myna is a member of the starling family. It is a resident or partially migratory species found in wooded habitats in India and Southeast Asia. The species name is after the distribution of a former subspecies in the Malabar region. While the chestnut-tailed starling is a winter visitor to peninsular India, the closely related resident breeding population with a white head is now treated as a full species, the Malabar starling (''Sturnia blythii''). Taxonomy and distribution The lack of monophyly in the earlier starling genera has led to this species being placed variously under genus ''Sturnia'', ''Sturnus'' and ''Temenuchus'' in the past (Zuccon ''et al.'', 2006) and studies have suggested the reuse of an old name ''Temenuchus'' for members of this clade. Later studies have suggested placement in the genus ''Sturnia''. There are two subspecies of the chestnut-tailed starling: ...

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 are distinguished from other orders of birds by the 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 clade of birds and among 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 clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passeri ...
