Barred Cuckoo-dove
The barred cuckoo-dove (''Macropygia unchall'') is a bird species in the family Columbidae. It is native to South and Southeast Asia, and listed as Least Concern on the IUCN Red List. Taxonomy German herpetologist Johann Georg Wagler first described the barred cuckoo-dove in 1827. It has three recognized subspecies: * ''M. u. tusalia'' (Blyth, 1843) * ''M. u. minor'' (Swinhoe, 1870) * ''M. u. unchall'' (Wagler, 1827) Description The barred cuckoo-dove has a buff coloured throat and forehead which becomes pinkish grey at the crown. measures in length, and weighs . Its iris is yellow or pale brown, the beak is black and short, and the feet are red. It has blackish brown upperparts. The back, mantle (between the nape and the starting of the back), rump, wing coverts, and scapulars have reddish brown fringes. The tail is blackish brown, and is heavily barred reddish brown. It is similar to the little cuckoo-dove, but it is much larger and darker ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nape
The nape is the back of the neck. In technical anatomical/medical terminology, the nape is also called the nucha (from the Medieval Latin rendering of the Arabic , "spinal marrow"). The corresponding adjective is ''nuchal'', as in the term ''nuchal rigidity'' for neck stiffness. In many mammals the nape bears a loose, non-sensitive area of skin, known as the scruff, by which a mother carries her young by her teeth, temporarily immobilizing it during transport. In the mating of cats the male will grip the female's scruff with his teeth to help immobilize her during the act, a form of pinch-induced behavioral inhibition Pinch-induced behavioural inhibition (PIBI), also called dorsal immobility, transport immobility or clipnosis, is a partially inert state which results from a gentle squeeze of the skin behind the neck. It is mostly observed among cats and allows .... Cultural connotations In traditional Japanese culture, the was one of the few areas of the body (other than ...

Birds Of Eastern Himalaya
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 ...

Macropygia
''Macropygia'' is a genus of bird in the pigeon and dove family Columbidae. The genus is one of three genera known as cuckoo-doves. They are long tailed, range between 27 and 45 cm in length and have brown plumage. The genus ranges from India and China through Indonesia and the Philippines to Vanuatu and Australia. The genus ''Macropygia'' was introduced in 1837 by the English naturalist William John Swainson. The name combines the Ancient Greek ''makros'' meaning "long" or "deep" and "-pugios" meaning "-rumped"). The type species is the brown cuckoo-dove (''Macropygia phasianella''). The genus contains the following 15 species: * Barred cuckoo-dove (''Macropygia unchall'') * Amboyna cuckoo-dove (''Macropygia amboinensis'') * Sultan's cuckoo-dove (''Macropygia doreya'') * Ruddy cuckoo-dove (''Macropygia emiliana'') * Enggano cuckoo-dove (''Macropygia cinnamomea'') * Barusan cuckoo-dove (''Macropygia modiglianii'') * Timor cuckoo-dove (''Macropygia magna'') * Tanimbar cuckoo ...

Encyclopedia Of Life
The ''Encyclopedia of Life'' (''EOL'') is a free, online encyclopedia intended to document all of the 1.9 million living species known to science. It is compiled from existing trusted databases curated by experts and with the assistance of non-experts throughout the world. It aims to build one "infinitely expandable" page for each species, including video, sound, images, graphics, as well as text. In addition, the Encyclopedia incorporates content from the Biodiversity Heritage Library, which digitizes millions of pages of printed literature from the world's major natural history libraries. The project was initially backed by a US$50 million funding commitment, led by the MacArthur Foundation and the Sloan Foundation, who provided US$20 million and US$5 million, respectively. The additional US$25 million came from five cornerstone institutions—the Field Museum, Harvard University, the Marine Biological Laboratory, the Missouri Botanical Garden, and the Smithsonian Institutio ...

Sikkim
Sikkim (; ) is a state in Northeastern India. It borders the Tibet Autonomous Region of China in the north and northeast, Bhutan in the east, Province No. 1 of Nepal in the west and West Bengal in the south. Sikkim is also close to the Siliguri Corridor, which borders Bangladesh. Sikkim is the least populous and second smallest among the Indian states. Situated in the Eastern Himalaya, Sikkim is notable for its biodiversity, including alpine and subtropical climates, as well as being a host to Kangchenjunga, the highest peak in India and third highest on Earth. Sikkim's capital and largest city is Gangtok. Almost 35% of the state is covered by Khangchendzonga National Park – a UNESCO World Heritage Site. The Kingdom of Sikkim was founded by the Namgyal dynasty in the 17th century. It was ruled by Buddhist priest-kings known as the Chogyal. It became a princely state of British India in 1890. Following Indian independence, Sikkim continued its protectorate status with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepcha People
The Lepcha (; also called Rongkup ( Lepcha: , ''Mútuncí Róngkup Rumkup'', "beloved children of the Róng and of God") and Rongpa ( Sikkimese: )) are among the indigenous peoples of the Indian state of Sikkim and Nepal, and number around 80,000. Many Lepcha are also found in western and southwestern Bhutan, Tibet, Darjeeling, the Province No. 1 of eastern Nepal, and in the hills of West Bengal. The Lepcha people are composed of four main distinct communities: the Renjóngmú of Sikkim; the Dámsángmú of Kalimpong, Kurseong, and Mirik; the ʔilámmú of Ilam District, Nepal; and the Promú of Samtse and Chukha in southwestern Bhutan. Origins The word Lepcha is considered to be the anglicised version of the Nepalese word ''lepche'' meaning "vile speakers" or "inarticulate speech". This was at first a derogatory nickname but is no longer seen as negative. The origin of the Lepcha is unknown. They may have originated in Myanmar or Tibet but the Lepcha people themselves fir ...

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Old-growth Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Ecosystems
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 factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Himalayas
The Himalayas, or Himalaya (; ; ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding in elevation lie in the Himalayas. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is tall. The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo–Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas.
