Seychelles Bulbul
The Seychelles bulbul (''Hypsipetes crassirostris'') is a member of the bulbul family of passerine birds. It is a common endemic species of the Seychelles, breeding on Mahé, Praslin, La Digue and Silhouette as well as some smaller islands. Taxonomy and systematics Alternative names for the Seychelles bulbul include the Seychelles black bulbul and thick-billed bulbul. The species is very closely related to both the Grand Comoro bulbul and the Moheli bulbul. Behaviour and ecology The Seychelles bulbul is social, living in pairs, family groups or small flocks in forest and woodland from the sea to the granitic mountains. The Seychelles bulbul is monogamous and territorial in the breeding season. The territory is about in diameter. It is defended against other bulbuls and potential predators with loud alarm calls, and even large intruders, including man, can be mobbed. A helper, probably a previous offspring, is tolerated but not allowed to approach the nest. Breeding The bree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Newton
Sir Edward Newton (10 November 1832 – 25 April 1897) was a British colonial administrator and ornithologist. He was born at Elveden Hall, Suffolk the sixth and youngest son of William Newton (MP for Ipswich), William Newton, MP. He was the brother of ornithologist Alfred Newton. He graduated from Magdelene College, Cambridge in 1857 and was one of the twenty founding members of the British Ornithologists' Union. Newton was the Chief Secretary (British Empire), Colonial Secretary for Mauritius from 1859 to 1877. From there he sent his brother a number of specimens, including the dodo and the Rodrigues solitaire, both already extinct. In 1878, Newton initiated the first laws anywhere specifically designed to protect indigenous land birds from persecution. Edward was later Colonial Secretary and Lieutenant-Governor of Jamaica (1877–1883). He married Mary Louisa Cranstoun, daughter of W.W.R. Kerr in 1869. She died the following year. He is commemorated in the binomial of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. Etymology The etymology of the word monsoon is not wholl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Seychelles
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Seychelles
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 ...

Hypsipetes
__NOTOC__ ''Hypsipetes'' is a genus of bulbuls, songbirds in the family Pycnonotidae. Most of its species occur in tropical forests around the Indian Ocean. But while the genus is quite diverse in the Madagascar region at the western end of its range it does not reach the African mainland. Most ''Hypsipetes'' bulbuls are dark greyish birds with orange or red bills and feet. The feathers on top of the head are slightly elongated and usually black, and can be erected to form a short and wispy crest. Taxonomy and systematics The genus ''Hypsipetes'' was introduced in 1831 by the Irish zoologist Nicholas Aylward Vigors with ''Hypsipetes psaroides'' as the type species. This taxon is now a subspecies of the black bulbul ''Hypsipetes leucocephalus psaroides''. The genus name combines the Ancient Greek ''hupsi'' meaning "high" with ''petēs'' meaning "-flyer". Species The genus contains 19 species: * Philippine bulbul (''Hypsipetes philippinus'') * Mindoro bulbul (''Hypsipetes mind ...

Seychelles Bulbul - Hypsipetes Crassirostris 2
Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to a m ...

Green-backed Heron
"Green-backed heron" is a collective term for certain herons. Small and compact among herons, these birds often feature green plumage – rare among the Ardeidae –, in particular on the back, wings and scapulars. They were formerly believed to make up a single species ''Butorides striata'', but are now treated as three largely allopatric species: * Striated heron, ''Butorides striata'' – Widespread throughout the Old World tropics and in South America (Note that the grammatical gender of the specific name has been corrected from ''striatus'') * Lava heron, ''Butorides sundevalli'' – Endemic to the Galápagos Islands off Ecuador * Green heron, ''Butorides virescens'' – Widespread from temperate North America south to Panama These herons are tool-using animals. They are regularly seen picking up objects to use as a fishing lure, attracting prey fish.Norris (1975), Boswall (1983), Walsh ''et al.'' (1985), Robinson (1994) Image:Striated Heron (But ...

Omnivorous
An omnivore () is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms (Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. Frugivores ...

Fledge
Fledging is the stage in a flying animal's life between hatching or birth and becoming capable of flight. This term is most frequently applied to birds, but is also used for bats. For altricial birds, those that spend more time in vulnerable condition in the nest, the nestling and fledging stage can be the same. For precocial birds, those that develop and leave the nest quickly, a short nestling stage precedes a longer fledging stage. All birds are considered to have fledged when the feathers and wing muscles are sufficiently developed for flight. A young bird that has recently fledged but is still dependent upon parental care and feeding is called a fledgling. People often want to help fledglings, as they appear vulnerable, but it is best to leave them alone. The USA National Phenology Network defines the phenophase (or life cycle stage) of fledged young for birds as "One or more young are seen recently departed from the nest. This includes young incapable of sustained fli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''.

Moheli Bulbul
The Moheli bulbul (''Hypsipetes moheliensis'') is a species of songbird in the bulbul family, Pycnonotidae. It is endemic to the Indian Ocean island of Mohéli. Its natural habitat is subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial f ...s. Until 2011, it was classified as a subspecies of the Grand Comoro bulbul. It is also considered a sister species to the Seychelles bulbul. Footnotes References * Benson, C.W. 1960.

Bulbul
The bulbuls are members of a family, Pycnonotidae, of medium-sized passerine songbirds, which also includes greenbuls, brownbuls, leafloves, and bristlebills. The family is distributed across most of Africa and into the Middle East, tropical Asia to Indonesia, and north as far as Japan. A few insular species occur on the tropical islands of the Indian Ocean. There are 160 species in 32 genera. While different species are found in a wide range of habitats, the African species are predominantly found in rainforest, whereas Asian bulbuls are predominantly found in more open areas. Taxonomy The family Pycnonotidae was introduced by the English zoologist George Robert Gray in 1840 as a subfamily Pycnonotinae of the thrush family Turdidae. The Arabic word ''bulbul'' (بلبل) is sometimes used to refer to the "nightingale" as well as the bulbul, but the English word ''bulbul'' refers to the birds discussed in this article.
