White-browed Shrike-babbler
The white-browed shrike-babbler (''Pteruthius aeralatus'') is a bird species found in the eastern Himalayas and Southeast Asia from northern Burma to southern Cambodia. Like others in the genus it is found in montane forests. Males and females have different plumages and variations occur through its range with several populations being treated as subspecies. It is part of a cryptic species complex and was earlier lumped as a subspecies of the white-browed shrike-babbler. Clements lumps this bird into the white-browed shrike-babbler. Description The white-browed shrike-babbler is sexually dimorphic. There are many variations between the populations and some are more distinctive than others but they may not be easy to diagnose in the field. In general appearance it is very similar to the Himalayan shrike-babbler but all subspecies with the exception of ''validirostris'' have the tertials of males partly coloured rufous and partly fulvous. The common name commemorates Edward B ... [...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] |

Birds Of The Himalayas
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur (''Semnopithecus schistaceus'') Lowland forests On the Indo-Gangetic plain at the base of the mountains, an alluvial plain drained by the Indus and Ganges-Brahmaputra river systems, vegetation varies from west to east with rainfall. The deserts and xeric shrublands, xeric Northwestern thorn scrub forests occupy the plains of Punjab, Pakistan, Pakistani and the Punjab, India, Indian Punjab. Further east lie the Upper Gangetic Plains moist deciduous forests of Uttarakhand and Uttar Pradesh and the Lower Gangetic Plains moist deciduous forests of Bi ...

Pteruthius
The shrike-babblers are a group of small birds in the genus ''Pteruthius''. They are native to the Indomalayan realm, and were traditionally placed in the family Timaliidae before molecular phylogenetic studies in 2007 found that they were best considered as belonging to the family Vireonidae which was then thought to be restricted to the New World. They were traditionally classified into five species with several subspecies but changes in the status of these species on the basis of the phylogenetic species concept suggest more forms in a cryptic species complex. Most species are found in montane forests, with some species descending down to lower altitudes during the winter. The shrike-babblers range in size from 11.5–20 cm in length and weigh 10-48 g. They are divergent in plumage and size but all possess a stout black hooked bill, short rictal bristles and a distinctive juvenile plumage. They all exhibit sexual dimorphism in plumage, with the males generally brighter. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic Species Concept
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes in zoologic ...

Edward Blyth
Edward Blyth (23 December 1810 – 27 December 1873) was an English zoologist who worked for most of his life in India as a curator of zoology at the museum of the Asiatic Society of India in Calcutta. Blyth was born in London in 1810. In 1841 he travelled to India to become the curator of the museum of the Royal Asiatic Society of Bengal. He set about updating the museum's catalogues, publishing a ''Catalogue of the Birds of the Asiatic Society'' in 1849. He was prevented from doing much fieldwork himself, but received and described bird specimens from A.O. Hume, Samuel Tickell, Robert Swinhoe and others. He remained as curator until 1862, when ill-health forced his return to England. His ''Natural History of the Cranes'' was published posthumously in 1881. Avian species bearing his name include Blyth's hornbill, Blyth's leaf warbler, Blyth's hawk-eagle, Blyth's olive bulbul, Blyth's parakeet, Blyth's frogmouth, Blyth's reed warbler, Blyth's rosefinch, Blyth's shrike-babbl ...

Himalayan Shrike-babbler
The Himalayan shrike-babbler (''Pteruthius aeralatus ripleyi'') is a bird subspecies found in the western Himalayas that belongs to the shrike-babbler group. The genus was once considered to be an aberrant Old World babbler and placed in the family Timaliidae until molecular phylogenetic studies showed them to be closely related to the vireos of the New World, leading to their addition in the family Vireonidae. Males and females have distinctive plumages, with the males being all black about with a cinnamon-rufous tertial patch and a distinctive white stripe running from behind the eye. The underside is whitish with some pinkish buff on the flanks. Females have a greyish head, lack the white stripe and have the upperparts and wings with greens, yellow and chestnut. The subspecies is part of a cryptic species complex that was earlier considered as one species, white-browed shrike-babbler (''P. flaviscapis'' in the broad sense) with several subspecies.
