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.

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] |
Mixed-species Foraging Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

Blyth's Shrike-babbler
Blyth's 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 (other), white-browed shrike-babbler. Clements lumps this bird into the white-browed shrike-babbler. Description Blyth's 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.

Handbook Of The Birds Of India And Pakistan
The ''Handbook of the Birds of India and Pakistan'' is the '' magnum opus'' of Indian ornithologist Salim Ali, written along with S. Dillon Ripley. Appended to the title is the phrase "''together with those of Bangladesh, Nepal, Sikkim, Bhutan and Sri Lanka''". The 10 volume work, often referred to as "the handbook", was started in 1964 and ended in 1974. A single volume "compact edition" of the "Handbook" was also produced and a supplementary illustrative work ''A Pictorial Guide to the Birds of the Indian Subcontinent'' with illustrations by John Henry Dick, coauthored with Dillon Ripley, was published in 1983. The plates from this supplement were incorporated in the second edition of the "Handbook". The second edition was completed by others, notably J. S.

George Shaw (biologist)
George Kearsley Shaw (10 December 1751 – 22 July 1813) was an English botanist and zoologist. Life Shaw was born at Bierton, Buckinghamshire, and was educated at Magdalen Hall, Oxford, receiving his M.A. in 1772. He took up the profession of medical practitioner. In 1786 he became the assistant lecturer in botany at the University of Oxford. He was a co-founder of the Linnean Society in 1788, and became a fellow of the Royal Society in 1789. In 1791 Shaw became assistant keeper of the natural history department at the British Museum, succeeding Edward Whitaker Gray as keeper in 1806. He found that most of the items donated to the museum by Hans Sloane were in very bad condition. Medical and anatomical material was sent to the museum at the Royal College of Surgeons, but many of the stuffed animals and birds had deteriorated and had to be burnt. He was succeeded after his death by his assistant Charles Konig. Works Shaw published one of the first English descriptions with s ...
