White-browed tit

The white-browed tit (Poecile superciliosus, formerly Parus superciliosus) is a species of bird in the tit family Paridae. It is endemic to the mountain forests of central China and Tibet.

It is 13.5–14 cm long, with a weight of 10–12 g. The plumage pattern is very similar to that of the western North American mountain chickadee P. gambeli (of which it has on occasion been considered a subspecies, despite its being on a different continent), differing in the breast and cheeks being rusty brown, not white, and having a longer and more sharply defined white eyebrow; the back is also a richer brown, not greyish-brown (del Hoyo et al. 2007).

It breeds in alpine shrub forests of Berberis, Rhamnus, Rhododendron, and Salix at 3,200–4,235 m altitude, descending in winter to slightly lower levels where it occurs in coniferous forests, primarily Picea. It nests on the ground in rock crevices or old rodent burrows (del Hoyo et al. 2007).

The genus name Poecile has often been treated as feminine (giving the species name ending superciliosa); however, this was not specified by the original genus author Johann Jakob Kaup, and under the rules of the ICZN, the genus name must therefore be treated by default as masculine, giving the name ending superciliosus (del Hoyo et al. 2007).

Aegithalidae

The bushtits or long-tailed tits, Aegithalidae, are a family of small, drab passerine birds with moderately long tails. The family contains 13 species in four genera, all but one of which are found in Eurasia. Bushtits are active birds, moving almost constantly while they forage for insects in shrubs and trees. During non-breeding season, birds live in flocks of up to 50 individuals. Several bushtit species display cooperative breeding behavior, also called helpers at the nest.

Andes

The Andes or Andean Mountains (Spanish: Cordillera de los Andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The Andes also have the 2nd most elevated highest peak of any mountain range, only behind the Himalayas. The range is 7,000 km (4,300 mi) long, 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and has an average height of about 4,000 m (13,000 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.

Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus – some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Sucre, Mérida and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes.

The Andes Mountains are the world's highest mountain range outside Asia. The highest mountain outside Asia, Argentina's Mount Aconcagua, rises to an elevation of about 6,961 m (22,838 ft) above sea level. The peak of Chimborazo in the Ecuadorian Andes is farther from the Earth's center than any other location on the Earth's surface, due to the equatorial bulge resulting from the Earth's rotation. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border, which rises to 6,893 m (22,615 ft).

The Andes are also part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America and Antarctica.

The Central Andean wet puna is a montane grasslands and shrublands ecoregion in the Andes of Peru and Bolivia.

Fauna of the Andes

The fauna of the Andes, a mountain range in South America, is large and diverse. As well as a huge variety of flora, the Andes contain many different animal species.

With almost 1,000 species, of which roughly 2/3 are endemic to the region, the Andes are the most important region in the world for amphibians.

The diversity of animals in the Andes is high, with almost 600 species of mammals (13% endemic), more than 1,700 species of birds (about 1/3 endemic), more than 600 species of reptiles (about 45% endemic), and almost 400 species of fish (about 1/3 endemic).

Leptopoecile

Leptopoecile is a genus of birds in the long-tailed tit family Aegithalidae. The genus was once placed in the large family Sylviidae, but analysis of mitochondrial DNA placed it with the long-tailed tits.The genus contains two species:

White-browed tit-warbler (Leptopoecile sophiae)

Crested tit-warbler (Leptopoecile elegans)

List of ovenbird species

Ovenbirds is the common name for the avian family Furnariidae, though none of its members bear that name. The common name derives from the horneros, which itself derives from the Spanish word for oven, horno, used to describe the shape of their nests. The International Ornithological Congress (IOC) recognizes 314 species in the family, distributed among three subfamilies and 69 genera.This list is presented according to the IOC taxonomic sequence and can also be sorted alphabetically by common name and binomial.

Nubra Valley

Nubra (Tibetan : ལྡུམ་ར; Wylie : ldum ra; English : Nubra) is a tri-armed valley located to the north east of Ladakh valley. Diskit the capital of Nubra is about 150 km north from Leh town, the capital of Ladakh district, India. Local scholars say that its original name was Ldumra (the valley of flowers). The Shyok River meets the Nubra or Siachan River to form a large valley that separates the Ladakh and Karakoram Ranges. The Shyok river is a tributary of the Indus river. The average altitude of the valley is about 10,000 ft. i.e. 3048 metres above the sea level. The common way to access this valley is to travel over the Khardung La pass from Leh town. Foreign nationals are required to get a Protected area permit to visit the Nubra Valley. Since 1 April 2017 Indian citizens are also required to get an Inner Line Permit to visit the valley.

Old World warbler

Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. A smaller family of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.

Poecile

Poecile is a genus of birds in the tit family Paridae. It contains 15 species, which are scattered across North America, Europe and Asia; the North American species are the chickadees. In the past, most authorities retained Poecile as a subgenus within the genus Parus, but treatment as a distinct genus, initiated by the American Ornithologists Union, is now widely accepted. This is supported by mtDNA cytochrome b sequence analysis.The genus Poecile was erected by the German naturalist Johann Jakob Kaup in 1829. The type species was subsequently designated as the marsh tit. The name Poecile is from Ancient Greek poikilos "colourful". A related word poikilidos denoted an unidentified small bird. It has traditionally been treated as feminine (giving name endings such as cincta); however, this was not specified by the original genus author Johann Jakob Kaup, and under the ICZN the genus name must therefore be treated by default as masculine, giving name endings such as cinctus.

Sanjiangyuan

The Sanjiangyuan (Chinese: 三江源; literally: 'Source of Three Rivers'), is an area of the Tibetan Plateau in Qinghai province, China which contains the headwaters of three great rivers of Asia: the Yellow, the Yangtze, and the Mekong. Parts of the area are protected as the Sanjiangyuan National Nature Reserve (SNNR), also called the Three Rivers Nature Reserve. The reserve consists of 18 subareas, each containing three zones which are managed with differing degrees of strictness.

Along with wetland and waters protection, other ecological values, such as grassland, forest, and wildlife enhancement, have also been presented as goals. To advance the goals of the SNNR uncontrolled or poorly managed mining, logging, hunting, and grazing have been curtailed. Foreign and other mining firms have replaced the uncontrolled miners, trees have been planted, and measures have been taken to protect endangered species. To protect the grasslands, pastoralists are not permitted to graze their animals in designated ‘core zones’ (see below), and grazing is supervised elsewhere in the SNNR. In addition, residents have been resettled from core zones and other grassland areas of the SNNR, and rangeland has been fenced and is in the process of being privatized throughout the Sanjiangyuan Area.

Tit-spinetail

Tit-spinetails are small passerine birds of the genus Leptasthenura, belonging to the ovenbird family Furnariidae. They are found in South America, particularly the southern and Andean parts of the continent. They are somewhat similar to birds of the tit family in their shape and feeding behaviour, hence the first part of their name. The "spinetail" part of their name refers to their long, pointed tail feathers. Tit-spinetails have short rounded wings, short pointed bills and are mainly brown in colour. Their nests are built in holes or in the old nests of other birds.

Tit (bird)

The tits, chickadees, and titmice constitute the Paridae, a large family of small passerine birds which occur mainly in the Northern Hemisphere and Africa. Most were formerly classified in the genus Parus.

While commonly referred to as "tits" throughout much of the English-speaking world, these birds are called either "chickadees" (onomatopoeic, derived from their distinctive "chick-a dee dee dee" alarm call) or "titmice" in North America. The name titmouse is recorded from the 14th century, composed of the Old English name for the bird, mase (Proto-Germanic *maison, German Meise), and tit, denoting something small. The former spelling, "titmose", was influenced by mouse in the 16th century. Emigrants to New Zealand presumably identified some of the superficially similar birds of the genus Petroica of the family Petroicidae, the Australian robins, as members of the tit family, giving them the title tomtit, although, in fact, they are not related.

These birds are mainly small, stocky, woodland species with short, stout bills. Some have crests. They range in length from 10 to 22 cm. They are adaptable birds, with a mixed diet including seeds and insects. Many species live around human habitation and come readily to bird feeders for nuts or seed, and learn to take other foods.

White-browed tit-spinetail

The white-browed tit-spinetail (Leptasthenura xenothorax) is a species of bird in the Furnariidae family. It is endemic to Peru.

Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.

White-browed tit-warbler

The white-browed tit-warbler (Leptopoecile sophiae) is a species of bird in the Aegithalidae family. It is resident in the Tian Shan and central China as well as in the Himalayas where it is mainly found in winter. Its natural habitat is boreal forests.

Four subspecies are recognised:

L. s. sophiae Severtsov, 1873 – southeast Kazakhstan to northwest China, northwest India and north Pakistan

L. s. stoliczkae (Hume, 1874) – south Xinjiang, west Qinghai and extreme west Xizang (west China)

L. s. major Menzbier, 1885 – west Xinjiang and north Qinghai (west China)

L. s. obscurus Przewalski, 1887 – central Nepal, south and southeast Xizang and south and east Qinghai to south Gansu and Sichuan (west China)

Willow tit

The willow tit (Poecile montanus) is a passerine bird in the tit family, Paridae. It is a widespread and common resident breeder throughout temperate and subarctic Europe and northern Asia. It is more of a conifer specialist than the closely related marsh tit, which explains it breeding much further north. It is resident, and most birds do not migrate.

In the east of its range it is much paler than marsh tit, but as one goes west the various races become increasingly similar, so much so that it was not recognised as a breeding bird in Great Britain until the end of the 19th century, despite being widespread. The British population has declined by 94% since 1970 making it the most threatened resident bird in Britain. It now the focus of a Back from the Brink project which aims to reverse this decline.The willow tit is distinguished from the marsh tit by a sooty brown instead of a glossy blue black cap; the general colour is otherwise similar, though the under parts are more buff and the flanks distinctly more rufous; the pale buff edgings to the secondaries form a light patch on the closed wing. The feathers of the crown and the black bib under the bill are longer, but this is not an easily noticed character. However, the more graduated tail (not square) shows distinctly when spread. Length is 11.5 cm, and wings range from 60–70 mm.

The commonest call is a nasal zee, zee, zee, but the notes of the bird evidently vary considerably. Occasionally a double note, ipsee, ipsee, is repeated four or five times.

The willow tit often excavates its own nesting hole, even piercing hard bark; this is usually in a rotten stump or in a tree, more or less decayed. Most nests examined are cups of felted material, such as fur, hair and wood chips, but feathers are sometimes used. The number of eggs varies from six to nine, with reddish spots or blotches..

Birds feed on insects, caterpillars, and seeds, much like other tits. This species is parasitised by the moorhen flea, Dasypsyllus gallinulae.
