White-bellied Heron
The white-bellied heron (''Ardea insignis'') also known as the imperial heron or great white-bellied heron, is a large heron species living in the foothills of the eastern Himalayas in northeast India and Bhutan to northern Myanmar. It inhabits undisturbed rivers and wetlands. It has been listed as Critically Endangered on the IUCN Red List since 2007, because the global population is estimated at less than 300 mature individuals and threatened by habitat loss and human disturbance. It is mostly dark grey with a white throat and underparts. Taxonomy The scientific name ''Ardea insignis'' was suggested by Brian Houghton Hodgson in 1844; he had presented a zoological specimen to the British Museum but a description was not published. This name was therefore considered a '' nomen nudum''. In 1878, Allan Octavian Hume described the differences between the white-bellied and the great-billed heron (''Ardea sumatrana''). The scientific name ''Ardea imperialis'' was suggested by E. C. St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namdapha National Park
Namdapha National Park is a large protected area in Arunachal Pradesh of Northeast India. The park was established in 1983. With more than 1,000 floral and about 1,400 faunal species, it is a biodiversity hotspot in the Eastern Himalayas. The national park harbours the northernmost lowland evergreen rainforests in the world at 27°N latitude. It also harbours extensive dipterocarp forests, comprising the northwestern parts of the Mizoram-Manipur-Kachin rain forests ecoregion. It is the fourth largest national park in India. History Namdapha was originally declared a Wildlife Sanctuary in 1972, then a National Park in 1983 and became a Tiger Reserve under the Project Tiger scheme in the same year. Its name was a combination of two Singpho words, namely "nam" which means water, and "dapha" which means origin – the river originates from the Dapha Bum glaciers. Geography and vegetation Namdapha National Park is located in Changlang district of the Northeast Indian state of A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pterospermum Acerifolium
''Pterospermum acerifolium'', the bayur tree or karnikara tree, is a flowering plant indigenous to Southeast Asia, from India to Burma. It is most likely to grow naturally along forested stream banks. The best growing conditions are a seasonally moist then dry climate with access to full sunlight. ''Pterospermum acerifolium'' is an angiosperm that is traditionally included in the family Sterculiaceae; however, it is grouped in the expanded family Malvaceae as well. The classification ''Pterospermum'' is based on two Greek words, Pteron and Sperma, meaning “winged seed” and the species name acerifolium indicates leaves shaped like a maple's. There is an array of common names for Pterospermum acerifolium, depending on the region where it is grown. It is commonly referred to as Kanak Champa, Muchakunda or Karnikar Tree within its native range. In the Philippines, it is known as Bayog. Other common names include Bayur Tree, Maple-Leafed Bayur Tree, and Dinner Plate Tree. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pinus Roxburghii
''Pinus roxburghii'', commonly known as chir pine or longleaf Indian pine, is a species of pine tree native to the Himalayas. It was named after William Roxburgh. Description ''Pinus roxburghii'' is a large tree reaching with a trunk diameter of up to , exceptionally . The bark is red-brown, thick and deeply fissured at the base of the trunk, thinner and flaky in the upper crown. The leaves are needle-like, in fascicles of three, very slender, long, and distinctly yellowish green. The cones are ovoid conic, long and broad at the base when closed, green at first, ripening glossy chestnut-brown when 24 months old. They open slowly over the next year or so, or after being heated by a forest fire, to release the seeds, opening to broad. The seeds are long, with a wing, and are wind- dispersed. Similar species ''Pinus roxburghii'' is closely related to '' P. canariensis'' (Canary Island pine), '' P. brutia'' (Turkish pine) and '' P. pinaster'' (maritime p ...

Sankosh River
Sankosh (also Mo Chu, and Svarnakosha) is a river that rises in northern Bhutan and empties into the Brahmaputra in the state of Assam in India. In Bhutan, it is known as the Puna Tsang Chu below the confluences of several tributaries near the town of Wangdue Phodrang. The two largest tributaries are the Mo Chhu and Pho Chhu, which flow together at Punakha. The Punakha dzong, which is situated immediately above the confluence of the two rivers, is one of the most beautiful dzongs in Bhutan and the winter residence of the Dratshang Lhentshog. The upper reaches of the Pho Chhu are susceptible to ice blockages, and the dzong has been damaged on several occasions by glacial lake outburst floods. After it enters in India, it flows on the border of Assam and West Bengal. At Wangdue Phodrang, elevation , the river is joined by the west flowing Tang Chuu and it enters a precipitous gorge. The highway running south from Wangdue Phodrang to Dagana follows the river for much of its cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing Chord (biology)
Wing chord is an anatomical measurement of a bird's wing. The measurement is taken with the wing bent at a 90-degree angle, from the most prominent point of the wrist joint to the most prominent point of the longest primary feather. It is often taken as a standard measurement of the proportions of a bird and used to differentiate between species and subspecies. See also * Bird measurement Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The measurements of the lengths of specific parts and the weights of birds varies between species, populations within species, between the sex ... References {{Bird-stub Bird anatomy ...

Ayeyarwady River
The Irrawaddy River ( Ayeyarwady River; , , from Indic ''revatī'', meaning "abounding in riches") is a river that flows from north to south through Myanmar (Burma). It is the country's largest river and most important commercial waterway. Originating from the confluence of the N'mai and Mali rivers, it flows relatively straight North-South before emptying through the Irrawaddy Delta in the Ayeyarwady Region into the Andaman Sea. Its drainage basin of about covers a large part of Burma. After Rudyard Kipling's poem, it is sometimes referred to as ' The Road to Mandalay'. As early as the sixth century, the river was used for trade and transport. Having developed an extensive network of irrigation canals, the river became important to the British Empire after it had colonized Burma. The river is still as vital today, as a considerable amount of (export) goods and traffic moves by river. Rice is produced in the Irrawaddy Delta, irrigated by water from the river. In 2007, Myanmar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covert Feather
A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or ''tectrices''), which, as the name implies, cover other feathers. The coverts help to smooth airflow over the wings and tail. Ear coverts The ear coverts are small feathers behind the bird's eye which cover the ear opening (the ear of a bird has no external features) Tail coverts The uppertail and undertail coverts cover the base of the tail feathers above and below. Sometimes these coverts are more specialised. The "tail" of a peacock is made of very elongated uppertail coverts. Wing coverts The upperwing coverts fall into two groups: those on the inner wing, which overlay the secondary flight feathers, known as the secondary coverts, and those on the outerwing, which overlay the primary flight feathers, the primary coverts. Within each group, the feathers form a number of rows. The feathers of the outermost, largest, row are termed greater (primary-/secondary-) coverts; those in the next row ...
