Top 20 Most Common Bird in Bhutan

The rufous sibia (Heterophasia capistrata) is a species of bird in the family Leiothrichidae. It feeds on berries and insects. It is found in the northern parts of the Indian subcontinent, ranging across India, Nepal and Bhutan. Its natural habitat is the temperate forests of the Lower to Middle Himalayas. The species has an unmistakable appearance with its rufous-dominated colouration and black head, and is often seen with its crest raised. It is a vigorous, melodious singer.

The white-collared blackbird (Turdus albocinctus) is a species of bird in the family Turdidae. It is found in the Indian subcontinent, ranging across Bangladesh, Bhutan, India, Myanmar, Nepal and Pakistan. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude shrubland. On the Tibetan Plateau White-collared Blackbirds can breed twice a year. The first breeding attempt results in small clutches where a few nestlings fledge in high body condition. Contrasting with the second attempt where larger clutches result in more chicks fledgling but these are in lower body condition. These differences are thought to be driven by parental feeding behaviour and seasonal variation in food availability. Field studies indicated that females, but not males, exhibit different nest defence behaviours that can be used to classify them into bold and shy personalities. Bold females had higher nest success compared to shy ones. White-collared Blackbirds feed their chicks plant material, especially berries, and invertebrates such as arthropods and annelids.

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 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 chestnut-crowned laughingthrush (Trochalopteron erythrocephalum) is a species of bird in the family Leiothrichidae. It is found in Bhutan, China, India, and Nepal. The silver-eared laughingthrush, formerly included as a subspecies, is now usually regarded as a separate species.

The green-backed tit (Parus monticolus) is a species of bird in the family Paridae. It is found in Bangladesh, Bhutan, China, India, Laos, Burma, Nepal, Pakistan, Taiwan and Vietnam. Its natural habitats are boreal forest, temperate forest, and subtropical or tropical moist lowland forest.

Length 66 cm (26 in), including tail of about 46 cm (18 in). Sexes alike. Head, neck, and breast black, with a white patch on the nape; remainder of lower plumage white, faintly tinged with lilac; whole upper plumage purplish-blue, brighter on the wings and tail; flight-feathers tipped with white, the outermost edged with the same; tail long and graduated, the feathers blue, broadly tipped with white, all except the very long central pair having a band of black in front of the white

The black bulbul is 24–25 cm (9.4–9.8 in) in length, with a long tail. The body plumage ranges from slate grey to shimmering black, depending on the race. The beak, legs, and feet are all orange and the head has a black fluffy crest. Sexes are similar in plumage, but young birds lack the crest, have whitish underparts with a grey breast band, and have a brown tint to the upperparts. They have a black streak behind the eye and on the ear coverts.

The species is 21–25 cm long and weighs 39-54 g. It is a shrike with long tail. The nominate race has black lowermost forehead (just over base of bill) and facial mask through lores and eye to rear ear-coverts; crown to nape and most of upperparts dark grey, small rufous rump patch; upperwing black, most wing-coverts, secondaries and tertials fringed pale rufous to whitish, sometimes tiny white patch at base of primaries (often lacking); tail chestnut-brown, tipped buffish, outermost pair of rectrices light brown; throat and undertail brownish-grey; iris dark brown; bill black or dark green; legs dull black or dark green. Sexes very similar. Juvenile is browner above than adult, with less marked brown (not black) facial mask, horn-colored lower mandible, has crown finely barred, upperparts and much of underparts heavily barred dark brownish. Race lahulensis is smaller and weaker-billed than nominate, also much paler, brownish-grey above, with rufous lower back and rump, white primary patch usually slightly larger and more visible, tail sometimes blackish (not brown). Voice: Rough, breathing-like call. Territorial call described as harsh zzert-zzert..., tchert-tchert... or tzert-tzert...; repertoire includes also a repeated ktcht-ktcht-ktcht given at dusk or as alarm. Breeding song subdued and musical, with mimicry of other bird calls lasting several minutes. Voice seems to be similar to that of L. schach.

The spotted nutcracker is a dark brown, broad-winged, short-tailed corvid. Body plumage is mid-to-dark chocolate brown, heavily spotted with white on face, neck, mantle and underparts. It has a large white loral spot, a white eye-ring, blackish-brown cap extending onto the nape, dark blackish wings with a greenish-blue gloss, all white vent, and dark tail with white corners above and a white terminal band on the undertail. In flight, broad wings, white vent and short tail are noticeable; the flight undulating. The black bill is slender and rather long, sharply pointed, and varies in size amongst races. The iris, legs and feet are black. Nutcrackers range from 32–38 cm in length (from tip of beak to tip of tail) and have a wingspan ranging from 49–53 cm. The voice is similar to that of the Eurasian jay and is loud and harsh. It is described as kraak-kraak-kraak-kraak.

The eurasian Tree Sparrow (Passer montanus) is a widespread sparrow of the European mainland that has been introduced to some parts of North America. Eurasian Tree Sparrow is very similar to the House sparrow (Passer domesticus) but it's smaller and neater. It prefers more natural habitats, at the edges of human activity, and inhabits farmlands, parklands, and open woods.

The white-throated laughingthrush (Pterorhinus albogularis) is a species of passerine bird in the family Leiothrichidae. It is found mainly in the northern regions of the Indian subcontinent, primarily the Himalayas, and some adjoining and disjunct areas. It ranges across Afghanistan, Bhutan, India, Myanmar, Nepal, Tibet and Vietnam. Its natural habitat is subtropical or tropical moist montane forests. This species was formerly placed in the genus Garrulax but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus Pterorhinus.

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.

The russet sparrow is a small chunky bird, with plumage warm rufous in overall colour. It is a medium-sized sparrow at 14 to 15 cm (5.5–5.9 in) and 18 to 22.5 grams (0.63–0.79 oz). It has a thick bill suited to eating seeds, which is black on the breeding male, horn-coloured on the non-breeding male, and yellowish with a dark tip on the female. Wingspans for males range between 6.8 to 8.2 cm (2.7–3.2 in) and those for females from 6.7 to 7.7 cm (2.6–3.0 in). Tail, bill, and tarsus lengths are 4.3 to 5.1 cm (1.7–2.0 in), 1.1 to 1.3 cm (0.43–0.51 in), and 1.6 to 1.8 cm (0.63–0.71 in), respectively. Measurements for the russet sparrow vary geographically, between the three subspecies, and also within the Himalayan subspecies cinnamomeus. The subspecies cinnamomeus is generally larger than the others, and within this form there is a tendency for birds at higher altitudes to be larger, and a clinal variation in size with the smallest birds in the west of the range and the largest in the east. The iris is chestnut in colour. The legs of both sexes are pale brown to pinkish-brown. The flight of all sparrows is swift, and that of the russet sparrow is described as swifter and more direct than that of the Eurasian tree sparrow.

The blue-fronted redstart (Phoenicurus frontalis) is a species of bird in the family Muscicapidae, the Old World flycatchers. It breeds in central China and the Himalayas (where it winters in the southern foothills, as well as in Yunnan, Northeast India and northern Southeast Asia). Its natural habitat is temperate forests. The female is brownish-grey, with paler underparts.

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.

It is slate-gray with a chestnut brown back. Its eyes are red. Its slender legs are pinkish-red. Its natural habitat is subtropical or tropical moist montane forests.

The spotted laughingthrush (Ianthocincla ocellata) is a bird species in the family Leiothrichidae. It is found in Bhutan, China, India, Myanmar, and Nepal. Its natural habitat is subtropical or tropical moist montane forests. The spotted laughingthrush was at one time placed in the genus Garrulax but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus Ianthocincla.

The house Crow is an intelligent bird that is near becoming a declared invasive species. The house Crow is very common in developed areas and can have a bold, aggressive personality. These birds have been known to damage and steal crops, affect local flora and fauna, create excessive noise, and carry diseases and parasites.

Hodgson's redstart (Phoenicurus hodgsoni) is a species of bird in the family Muscicapidae. It is found in Bhutan, China, India, Myanmar, and Nepal. Its natural habitat is temperate forests. It is a winter visitor in the Himalayas.
