Leptocoma Zeylonica
The purple-rumped sunbird (''Leptocoma zeylonica'') is a sunbird endemic to the Indian Subcontinent. Like other sunbirds, they are small in size, feeding mainly on nectar but sometimes take insects, particularly when feeding young. They can hover for short durations but usually perch to lap nectar from flowers. They build a hanging pouch nest made up of cobwebs, lichens and plant material. Males are contrastingly coloured but females are olive above and yellow to buff below. Males are easily distinguished from the purple sunbird by the light coloured underside while females can be told apart from females by their whitish throats. Description Purple-rumped sunbirds are tiny, at less than 10 cm long. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations for nectar feeding. Purple-rumped sunbirds are sexually dimorphic. The males have a dark maroon upperside with a blue-green crown that glistens at some angles, bright green shoulde ...

Calliandra
''Calliandra'' is a genus of flowering plants in the pea family, Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It contains about 140 species that are native to tropical and subtropical regions of the Americas. Description The genus comprises herbaceous perennial plants, shrubs, and rarely small trees, growing tall, with bipinnate leaves. The flowers are produced in cylindrical or globose inflorescences and have numerous long slender stamens which give rise to the common names powder-puff, powder puff plant, and fairy duster. These plants flower all year round, but the best blooming is in spring and summer. They can be easily pruned. Calliandra are often fed on by caterpillars, such as the larvae of statira sulphur (''Aphrissa statira''). It is available in many vibrant colours such as pink, white, etc. Species The following is an alphabetical listing of the 149 species in the genus ''Genus'' that are accepted by Plants of the World Online * ''Calliandra ...

Helpers At The Nest
Helpers at the nest is a term used in behavioural ecology and evolutionary biology to describe a social structure in which juveniles and sexually mature adolescents of either one or both sexes remain in association with their parents and help them raise subsequent broods or litters, instead of dispersing and beginning to reproduce themselves. This phenomenon was first studied in birds where it occurs most frequently, but it is also known in animals from many different groups including mammals and insects. It is a simple form of co-operative breeding. The effects of helpers usually amount to a net benefit, however, benefits are not uniformly distributed by all helpers nor across all species that exhibit this behaviour. There are multiple proposed explanations for the behaviour, but its variability and broad taxonomic occurrences result in simultaneously plausible theories.Dickinson, J. L.; Hatchwell, B. J.

Birds Of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. The bird life of Sri Lanka is very rich for its size and 524 species have been recorded. In addition to the many resident birds, a considerable number of bird migration, migratory species winter in the country to escape their northern breeding grounds. 34 species are confirmed as endemic (ecology), endemic. The other resident species are also found in the nearby Indian mainland, but over 80 have developed distinct Sri Lankan races. Some of these races are very different in their plumage characteristics from the related forms in India. 26 species are globally threatened. Bird distribution in Sri Lanka is largely determined by its climatic zones. The dry zone is largest of the three, covering more than half of the island, with a prolonged dry and hot period and only one monsoon (the north east monsoon from October to January). The wet zone, with two monsoons, is in the south western quarter of the island, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of Bangladesh
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. Birds ...

Leptocoma
''Leptocoma'' is a genus of sunbirds found from tropical South Asia to Papua New Guinea. Its members are sometimes included in '' Nectarinia''. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed. Taxonomy The genus was introduced by the German ornithologist Jean Cabanis in 1850 with Van Hasselt's sunbird as the type species. The name ''Leptocoma'' combines the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic p ... words ''leptos'' "delicate" or "fine" and ''komē'' "hair".

Rubber Fig
''Ficus elastica'', the rubber fig, rubber bush, rubber tree, rubber plant, or Indian rubber bush, Indian rubber tree, is a species of flowering plant in the family Moraceae, native to eastern parts of South and Southeast Asia. It has become naturalized in Sri Lanka, the West Indies, and the US state of Florida. Description It is a large tree in the banyan group of figs, growing to – rarely up to – tall, with a stout trunk up to in diameter. The trunk develops aerial and buttressing roots to anchor it in the soil and help support heavy branches. It has broad shiny oval leaves long and broad; leaf size is largest on young plants (occasionally to long), much smaller on old trees (typically long). The leaves develop inside a sheath at the apical meristem, which grows larger as the new leaf develops. When it is mature, it unfurls and the sheath drops off the plant. Inside the new leaf, another immature leaf is waiting to develop. Pollination and fruiting As with oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectar Robbing
Nectar robbing is a foraging behavior utilized by some organisms that feed on floral nectar, carried out by feeding from holes bitten in flowers, rather than by entering through the flowers' natural openings. "Nectar robbers" usually feed in this way, avoiding contact with the floral reproductive structures, and therefore do not facilitate plant reproduction via pollination. Because many species that act as pollinators also act as nectar robbers, nectar robbing is considered to be a form of exploitation of plant-pollinator mutualism. While there is variation in the dependency on nectar for robber species, most species rob facultatively. Nectar robbers vary greatly in species diversity and include species of carpenter bees, bumblebees, stingless ''Trigona'' bees, solitary bees, wasps, ants, hummingbirds, and some passerine birds, including flowerpiercers. Nectar robbing mammals include a fruit bat and Swinhoe's striped squirrel, which robs nectar from the ginger plant. History R ...

Woodfordia
''Zosterops'' (meaning "eye-girdle") is a genus of passerine birds containing the typical white-eyes in the white-eye family Zosteropidae. The genus has the largest number of species in the white-eye family. They occur in the Afrotropical, Indomalayan, and Australasian realms. Typical white-eyes have a length of between . Their most characteristic feature is a conspicuous white feather ring around the eye, though some species lack it. The species in this group vary in the structural adaptations of the tongue. The ''Zosterops'' 'griseotinctus''group is an example of a "great speciator" inhabiting a vast area and showing a remarkable morphological differentiation on islands, some of which maybe as close as apart. Systematics The genus ''Zosterops'' was introduced by the naturalists Nicholas Vigors and Thomas Horsfield in 1827. The name combines the Ancient Greek words ''zōstēros'' "belt" or "girdle" and ''ōpos'' "eye". The type species was designated as the Malagasy white-eye ...
