Top 20 Most Common Bird in Uttarakhand

The Himalayan bulbul is about 18 cm in length, with a wingspan of 25.5–28 cm and an average weight of 30 g. Its head, throat, and crest are black and white. The back, side, and lengthy tail are brown, the underside is pale yellow. Sexes have similar plumage. The song is a beautiful 4-piece whistle, which resembles an accelerated oriole whistle.

This bird is small (about 8–9 cm long) with yellowish olive upper parts, a white eye ring, yellow throat and vent. The belly is whitish grey but may have yellow in some subspecies. The sexes look similar. The species is widespread and is part of a superspecies complex that includes Zosterops japonicus, Zosterops meyeni and possibly others. The taxonomy of the group is still unclear with some island populations being distinctive while some subspecies are not well supported. The population from Flores, Indonesia for instance is found closer to the pale white-eye. The family itself is now questioned since they are nested along with the Stachyris babblers. About eleven subspecies are well recognised. These include the nominate form (type locality Bengal, India) which is found from Oman and Arabia, Afghanistan, northern India and extends into China and northern Myanmar. The population in the Western Ghats and hills of southern India is placed in nilgiriensis while salimalii of the Eastern Ghats hills (Shevaroy, Chitteri, Seshachalam, Nallamalai) is sometimes subsumed into the nominate race. The population of the plains of India, Laccadives and Sri Lanka are sometimes placed in egregius (= egregia) but is restricted by other works to the population in Sri Lanka. The populations in southern Myanmar, Thailand and Laos are placed in siamensis. The Nicobar Islands form is nicobaricus and is sometimes also used for the population on the Andaman Islands which are however distinctive and a distinct unnamed population. The populations from southern Thailand to western Cambodia are placed in williamsoni. Other Southeast Asian island forms include auriventer (=aureiventer), buxtoni, melanurus and unicus. Race occidentis (now often subsumed into the nominate race) of the Western Himalayas has the upper side dark green and the flanks are tinged in brown. The form salimalii has a shorter bill and is brighter yellow-green above. Some authors consider the nominate race to be restricted to Sikkim, Bhutan, Assam and Yunnan and consider the peninsular race as occidentis (or amabilis if the form from Kathiawar described by Koelz is considered valid). In Sri Lanka, race egregia is smaller and has a brighter back and throat than the endemic Sri Lanka white-eye, Zosterops ceylonensis found in the central hills.

The rose-ringed Parakeet is a very common sight in tropical climates and a variety of environments throughout the world. These colorful birds are popular as pets but can become a threatening invasive species to non-native ecosystems. They eat fruits, nuts, seeds, and grains, and can become serious pests to farmers. These birds are very vocal and very loud and come in several subspecies.

Black Kite is a bird of prey known for its aerial skills and hunting ability. Its striking appearance makes it a fascinating species to observe, and it can often be seen soaring through the skies. Black Kite is highly adaptable and can be found in a variety of habitats, making it a common sight in many areas.

The red-vented Bulbul is considered a pest by gardeners as it eats fruits and vegetables and spreads seeds to non-native regions. Because of this, these bird is considered an invasive species in some countries. The red-vented Bulbul is loud and can become aggressive to other birds and even humans in their forest, shrubland, and urban habitats.

The rock Pigeon is a wild ancestor of all domestic and feral pigeons, inhabiting coasts, cliffs, and caves. Pairs nest in rock crevices, often mating for life. They are known for their ability to fly very long distances to return to their homes, navigating using the sun's position and the earth's magnetic fields. Thanks to this ability, pigeons were used as messengers, particularly during World Wars I and II.

The overall size (length: 46–59 cm; 18–23 in.) and body proportions vary regionally. In the far northeast in Japan, the Kuriles and the Sakhalin peninsula, it is somewhat larger than the carrion crow. All taxa have a relatively long bill with the upper one quite thick and arched, making it look heavy and almost raven-like. Generally, all taxa have dark greyish plumage from the back of the head, neck, shoulders and lower body. Their wings, tail, face, and throat are glossy black. The depth of the grey shading varies across its range.

Like others in the genus, it has a broad black ventral line and has no crest. This tit is part of a confusing group of species but is distinct in having a grey-back, black hood, white cheek patch and a white wing-bar. The underparts are white with the black central stripe running along the length. The female has a narrower ventral line and is slightly duller. The upper tail coverts are ashy while the tail is black with the central 4 pairs of feathers ashy on the outer webs and all but the central pair are tipped white. The fifth pair is white with a black rachis and a band of black on the inner web. The outermost pair of tail feathers are all white with a black shaft. The undertail coverts are black towards the centre but white on the sides.

The grey-hooded warbler (Phylloscopus xanthoschistos) is a species of leaf warbler (family Phylloscopidae). It is most famous for the way it warbles. It was formerly included in the "Old World warbler" assemblage. It is found in the Himalayas. Its natural habitat is temperate forests.

The grey treepie is 36–40 cm (14–16 in) long and weighs 89–121 g (3.1–4.3 oz). It is the same size as other Dendrocitta species and is separated from them by the overall grey colour of the body. The races in the western part of the distribution have a greyish rump and some grey in tail while the eastern forms have a white rump and a black tail. The face and throat are dark and black with a diffuse mask. The body is grey on the underside becoming whiter towards the vent. The back and scapulars are brownish. The crown and nape are greyish and the black wing has a prominent white carpal patch. The vent is rufous and the outer tail feathers and tips of the central feathers are black. The beak is black, the legs are blackish-brown and the eyes are red or reddish-brown. The two sexes are similar. The juvenile bird is duller, with a browner nape, and all of its feathers have rufous tips. The species occupies a large geographical range and has several recognised regional forms that differ slightly from one another for instance in colour and tail length. These include occidentalis of the western Himalayan foothills (identified by its slightly longer tail), himalayana from the central Himalayas east into Thailand and Vietnam. A disjunct population, said to have a smaller or narrower bill, is found in the Eastern Ghats of peninsular India, sarkari, that is sometimes subsumed into himalayana. The Southeast Asian races include assimilis, sapiens, sinica, formosae (the nominate race from Taiwan) and insulae (Hainan Island). It has been suggested that this species forms a superspecies along with Dendrocitta occipitalis and Dendrocitta cinerascens.

This whistling thrush is dark violet blue with shiny spangling on the tips of the body feathers other than on the lores, abdomen and under the tail. The wing coverts are a slightly different shade of blue and the median coverts have white spots at their tips. The bill is yellow and stands in contrast. The inner webs of the flight and tail feathers is black. The sexes are similar in plumage. It measures 31–35 cm (12–14 in) in length. Weight across the subspecies can range from 136 to 231 g (4.8 to 8.1 oz). For comparison, the blue whistling thrush commonly weighs twice as much as an American robin. This species is possibly the largest extant thrush though size overlap does occur with the similar by length great thrush and the insular Amami thrush, whose mean body mass falls around the middle of those of the whistling thrush. Among standard measurements, the wing chord can measure 15.5–20 cm (6.1–7.9 in) long, the tarsus is 4.5–5.5 cm (1.8–2.2 in) and the bill is 2.9–4.6 cm (1.1–1.8 in). Size varies across the range with larger thrushes found to the north of the species range and slightly smaller ones to the south, corresponding with Bergmann's rule. In northern China, males and females average 188 g (6.6 oz) and 171 g (6.0 oz), whereas in India they average 167.5 g (5.91 oz) and 158.5 g (5.59 oz). Several populations are given subspecies status. The nominate form with a black bill is found in central and eastern China. The population in Afghanistan, turkestanicus, is often included in the widespread temminckii which has a smaller bill width at the base and is found along the Himalayas east to northern Burma. The population eugenei, which lacks white spots on the median coverts, is found south into Thailand. Cambodia and the Malay peninsula have crassirostris, while dichrorhynchus with smaller spangles occurs further south and in Sumatra. The Javan population, flavirostris, has the thickest bill. The subspecies status of several populations has been questioned.

The adult white-throated fantail is about 19 cm long. It has a dark fan-shaped tail, edged in white, and white supercilium and throat. There is otherwise much variation in plumage between races. Most resemble the Himalayan R. a. canescans which is mainly slate grey above and below, with a black eye mask, and a white throat and eyebrow. Local names for the bird in India include Nasoni sorai (Assamese).

This species, like most babblers, is non-migratory, and has short rounded wings and a weak flight. The sexes are identical, drably coloured in brownish grey with a yellow-bill making them confusable only with the endemic yellow-billed babblers of peninsular India and Sri Lanka. The upperparts are usually slightly darker in shade and there is some mottling on the throat and breast.

Hume's leaf warbler is one of the smallest "Old World warblers". Like most other leaf warblers, it has greenish upperparts and off-white underparts. With its long supercilium, crown stripe and yellow-margined tertial remiges, it is very similar to the yellow-browed warbler (P. inornatus). However, it has only one prominent light wing bar, just a faint vestige of the second shorter wing bar, and overall duller colours. It also has a dark lower mandible and legs. Its song is buzzing and high pitched. The best distinction from the yellow-browed warbler is the more disyllabic call. While the eastern and western Hume's leaf warblers already show noticeable differences in mtDNA sequence and calls, their songs do not differ; they are reproductively isolated only by allopatry and not usually considered separate species.

The Indian grey hornbill is a medium-sized hornbill, measuring around 61 cm (24 in) in length. The upper parts are greyish brown and there is a slight trace of a pale supercilium. The ear coverts are darker. The flight feathers of the wing are dark brown with a whitish tip. The tail has a white tip and a dark subterminal band. They have a red iris and the eyelids have eyelashes. The casque is short and pointed. The male has a larger casque on a dark bill, and the culmen and lower mandible are yellowish. The bare skin around the eye is dark in the male, but sometimes pale reddish in females. The female has a more yellowish bill with black on the basal half and on the casque. The juveniles lack the casque, and the bare skin around the eye is dull orange.

The spotted Dove is a medium-sized bird that is swift in flight. It prefers to live year-round in warm climates in suburban areas, especially in parks. Their nests are mostly made out of sticks and they like to dine on insects and seeds.

The oriental Turtle-dove is a migratory bird whose appearance can vary between subspecies. Individuals from higher latitudes migrate south over the winter months while those at lower latitudes do not migrate. The oriental Turtle-dove can be found in a large range of habitats, but usually prefers dense tree coverage. These birds mainly forage for seeds on the ground.

The common Tailorbird is famous for its nests, which are leaves that have been sewn together. Also known as Orthotomus sutorius, it is found across tropical regions in Asia and can be identified by its long, erect tail. The male and female take care of the chicks, and there have been recorded cases of a pair adopting chicks from another couple.
