Chloropsis Aurifrons Frontalis
The leafbirds (Chloropseidae) are a family of small passerine bird species found in the Indian Subcontinent and Southeast Asia. They were formerly grouped with the ioras and fairy-bluebirds in the family Irenidae. As presently defined, the leafbird family is monogeneric, with all species placed in the genus ''Chloropsis''. A large molecular phylogenetic study published in 2019 found that the family Chloropseidae is sister to the family Irenidae containing the fairy-bluebirds. Description The leafbirds range in size from , and in weight from . They resemble bulbuls, but whereas that group tends to be drab in colour, leafbirds are brightly plumaged, with the predominant green over the body giving rise to their common name. The family is mostly sexually dimorphic in their plumage, this can vary from the highly dimorphic orange-bellied leafbird to the Philippine leafbird, which exhibits no sexual dimorphism. Most of the differences between the sexes are in the extent of the other c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden-fronted Leafbird
The golden-fronted leafbird (''Chloropsis aurifrons'') is a species of leafbird. It is found from the Indian subcontinent and south-western China, to south-east Asia and Sumatra. It builds its bird nest, nest in a tree, laying 2-3 bird egg, eggs. This species eats insects and berries. Taxonomy and systematics Formerly, the Sumatran leafbird was considered as a subspecies, but the two differ extensively in morphology (biology), morphology and other characteristics. Description The adult is green-bodied with a black face and throat bordered with yellow. It has dark brown Iris (anatomy), irises and blackish feet and bill. It has a yellowish orange forehead and blue moustachial line (but lacks the blue flight feathers and tail sides of blue-winged leafbird). Young birds have a plain green head and lack the black on their face and throat. The black of the face and throat appears slightly duller in females. The southern Indian race, '' C. a. frontalis'', has a narrower yellow bord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feather
Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and an example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection. The study of feathers is called plumology (or plumage science). People use feathers in many ways that are practical, cultural, and religious. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter clothing and outdoor bedding, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumatra
Sumatra () is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the list of islands by area, sixth-largest island in the world at 482,286.55 km2 (182,812 mi.2), including adjacent islands such as the Simeulue Island, Simeulue, Nias Island, Nias, Mentawai Islands, Mentawai, Enggano Island, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai Islands, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa archipelago, separates Sumatra from Java. The northern tip of Sumatra is near ...

Bornean Leafbird
The Bornean leafbird (''Chloropsis kinabaluensis''), also known as the Kinabalu leafbird, is a species of bird in the family Chloropseidae. It is found in humid forest in Borneo, to which it is endemic (elevated areas, including the Meratus Mountains). It has traditionally been considered a subspecies of the blue-winged leafbird (''C. cochinchinensis''), but differ in measurements and morphology, the female Bornean leafbird having a distinctive male-like plumage Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers.

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Yellow-throated Leafbird
The yellow-throated leafbird (''Chloropsis palawanensis'') is a species of bird in the family Chloropseidae. It is endemic to the Palawan in the Philippines. Its natural habitat is tropical moist lowland forest. Along with the Philippine leafbird, it is one of the two endemic leafbirds in the country. Description and taxonomy Ebird describes it as "A medium-sized bird of lowland forest canopy and edge on Palawan and neighboring islands. Overall bright green, paler below, with a yellow throat and upper chest and a blue eye-ring, shoulder, edge to the wing, and short line down from the base of the bill. Note the black bill, wingtips, and legs. No other green birds of this size occur in its range. Voice includes a varied whistled song." It is slightly smaller than the Philippine leafbird and is generally more colorful with its bright yellow throat and blue lores and edges of its wing. This is monotypic and has no subspecies.

Blue-masked Leafbird
The blue-masked leafbird (''Chloropsis venusta'') is a species of bird in the family Chloropseidae. It is endemic to humid montane forest in the western regions of the Indonesian island of Sumatra. Generally, it lives in areas from 600 to 1,500 m (1,969–4,921 ft) in elevation. It is the smallest species of leafbird. It is considered near threatened due to habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species.

Jerdon's Leafbird
Jerdon's leafbird (''Chloropsis jerdoni'') is a species of leafbird found in forest and woodland in India and Sri Lanka. Its name honours Thomas C. Jerdon. It has traditionally been considered a subspecies of the blue-winged leafbird (''C. cochinchinensis''), but differ in measurements and morphology, it lacking the blue flight feathers for which the blue-winged leafbird was named. It builds its nest in a tree, and lays 2–3 eggs. This species eats insects, fruit and nectar. The male is green-bodied with a yellow-tinged head, black face and throat. It has a blue moustachial line. The female differs in that it has a greener head and blue throat, and young birds are like the female but without the blue throat patch. Like other leafbirds, the call of Jerdon's leafbird consists of a rich mixture of imitations of the calls of various other species of birds. They are very shy of water, will only come down to drink for very short periods and are quick to flee. Gallery File:Goldman ...

Snake
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, althoug ...

Bird Vocalization
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs (often simply ''birdsong'') are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the " winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
