John Whitehead (explorer)
John Whitehead (30 June 1860 – 2 June 1899) was an English explorer, naturalist and professional collector of natural history specimens in Southeast Asia. He is the first documented person to reach the summit of Mount Kinabalu: this was in 1888, after annual attempts from 1885. Whitehead was born in Colney Hatch Lane, Muswell Hill, Middlesex to Jeffery Whitehead, a stockbroker, and his wife Jane Ashton Tinker. After education at Elstree, Hertfordshire and the Edinburgh Institution he faced health problems and was sent to recuperate to Engadine in Switzerland in 1881 and then to warm Corsica in 1882 where he discovered a bird new to science, the Corsican nuthatch. Whitehead travelled in Malacca, North Borneo, Java, and Palawan between 1885 and 1888, where he collected a number of zoological specimens new to science, including 45 new species of bird such as Whitehead's broadbill ('' Calyptomena whiteheadi''), writing up his experiences in a book on his return. Between 1893 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Mindoro
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Halcon
Mount Halcon ( fil, Bundok Halcon) and ( es, Monte Halcón) is the highest mountain in the island of Mindoro in the Philippines, according to the new data release by ''Oriental Mindoro peakvisor'' as of 2022, it has an elevation of above sea level, higher than the previous estimates data at . It is the 23rd-highest peak in the Philippines and 37th-highest peak of an island on Earth. Its steep slopes have earned it the reputation of being one of the most difficult and technically most challenging mountain to climb in the Philippines. The first documented ascent was made in 1906 by American botanist Elmer Drew Merrill and a party of forestry and military personnel. Inhabitants Mount Halcon is home to the indigenous Alangan Mangyans.Alangan Mangyan. ''National Commission on Indigenous Peoples.'' . ''Accessed on 2011-09-15.''

Endangered Species (IUCN Status)
Endangered species as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively. IUCN Red List The IUCN Red List is a list of species which have been assessed according to a system of assigning a global conservation status. According to the latest system used by the IUCN, a species can be "Data Deficient" (DD) species – species for which more data and assessment is required before their situation may be determined – as well species comprehensively assessed by the IUCN's species assessment process. A species can be "Near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disyllabic
A syllable is a unit of organization for a sequence of speech sounds typically made up of a syllable nucleus (most often a vowel) with optional initial and final margins (typically, consonants). Syllables are often considered the phonological "building blocks" of words. They can influence the rhythm of a language, its prosody, its poetic metre and its stress patterns. Speech can usually be divided up into a whole number of syllables: for example, the word ''ignite'' is made of two syllables: ''ig'' and ''nite''. Syllabic writing began several hundred years before the first letters. The earliest recorded syllables are on tablets written around 2800 BC in the Sumerian city of Ur. This shift from pictograms to syllables has been called "the most important advance in the history of writing". A word that consists of a single syllable (like English ''dog'') is called a monosyllable (and is said to be ''monosyllabic''). Similar terms include disyllable (and ''disyllabic''; also ''bis ...

Columba Vitiensis
The metallic pigeon, (''Columba vitiensis'') also known as white-throated pigeon is a medium-sized, up to 37 cm long, bird in the family Columbidae.

Ptilinopus
The fruit doves, also known as fruit pigeons, are a genus (''Ptilinopus'') of birds in the pigeon and dove family (Columbidae). These colourful, frugivorous doves are found in forests and woodlands in Southeast Asia and Oceania. It is a large genus with over 50 species, some threatened or already extinct. Taxonomy The genus ''Ptilinopus'' was introduced in 1825 by the English naturalist William John Swainson with the rose-crowned fruit dove (''Ptilinopus regina'') as the type species. The genus name combines the Ancient Greek meaning "feather" with meaning "foot". The many species of this genus can be further grouped by geography and by certain shared characteristics. The fruit doves of the Sunda Islands and northern Australia, such as the pink-headed fruit dove and banded fruit dove, have comparatively longer tails than other species, and are notable for their solid colouration on the head, neck and breast, with a black band across the belly. Another grouping can be made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ducula Forsteni
The white-bellied imperial pigeon (''Ducula forsteni'') is a species of bird in the pigeon family Columbidae. First described by the French ornithologist Charles Lucien Bonaparte in 1854, it is endemic to Indonesia, where it is found on Sulawesi, Buton, Taliabu, Togian, and Peleng. It inhabits primary forest, dense secondary forest, and isolated areas of hill forest. A large pigeon with a long tail, it measures long and weighs on average. Males are mainly green, with pale-grey heads and bellies, chestnut vents, and a pale grey tail band, along with a red orbital ring. Females are nearly identical, but have darker grey areas in their plumage. The white-bellied imperial pigeon feeds on fruit. It is listed as being of least concern by the International Union for Conservation of Nature (IUCN) on the IUCN Red List due to its sufficiently large range and lack of significant population decline. However, its population is declining due to habitat destruction. Taxonomy and systemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ducula Poliocephala
''Ducula'' is a genus of the pigeon family Columbidae, collectively known as imperial pigeons. They are large to very large pigeons with a heavy build and medium to long tails. They are arboreal, feed mainly on fruit and are closely related to the other genus of fruit-eating doves, ''Ptilinopus''. Both genera display brightly coloured plumage, predominantly green, often with contrasting under-parts of purple, orange or red. Some ''Ducula'' have prominently swollen ceres. They have large gapes and swallow seeds whole, playing an important role in seed dispersal. Imperial pigeons are found in forests of southern Asia, New Guinea, northern Australia and the Pacific islands. Many species are nomadic, travelling long distances to exploit seasonal fruit sources. Some undertake migrations and all are strong fliers. Because of habitat loss and predation, species of ''Ducula'' are amongst the most threatened of avian species globally.
