Top 20 Most Common Bird in Narayani

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 common Myna is a large, stocky starling that prefers to live near humans in towns and suburban areas. It forages among tall grasses for grasshoppers; in fact, its scientific name, Acridotheres tristis, means "grasshopper hunter." The common Myna likes to maintain two roosts at the same time - both a temporary summer roost near the breeding site as well as a year-round roost where the female can sit and brood.

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.

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.

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 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.

This bird is glossy black with a wide fork to the tail. Adults usually have a small white spot at the base of the gape. The iris is dark brown (not crimson as in the similar ashy drongo). The sexes cannot be told apart in the field. Juveniles are brownish and may have some white barring or speckling towards the belly and vent, and can be mistaken for the white-bellied drongo. First-year birds have white tips to the feathers of the belly, while second-years have these white-tipped feathers restricted to the vent. They are aggressive and fearless birds, and although only 28 cm (11 in) in length, they will attack much larger species that enter their nesting territory, including crows and birds of prey. This behaviour led to their former name of king crow. They fly with strong flaps of the wing and are capable of fast manoeuvres that enable them to capture flying insects. With short legs, they sit upright on thorny bushes, bare perches or electricity wires. They may also perch on grazing animals. They are capable of producing a wide range of calls but a common call is a two note tee-hee call resembling that of the shikra (Accipiter badius).

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.

Cattle Egrets are short, thick-necked egrets. Their name refers to their preference to follow along with livestock as they forage in fields. Cattle Egrets were native only to Africa until the late 1800s when they somehow made their way throughout the Americas. They can often be found along airport runways waiting for planes to take off and blow insects out of the grass and weeds. They also follow behind farm equipment and do the same thing.

This species is 19 centimetres (7.5 in) long, including the long tail, which is usually held cocked upright when hopping on the ground. When they are singing a song the tail is normal like other birds. It is similar in shape to the smaller European robin, but is longer-tailed. The male has black upperparts, head and throat apart from a white shoulder patch. The underparts and the sides of the long tail are white. Females are greyish black above and greyish white. Young birds have scaly brown upperparts and head. It is the national bird of Bangladesh. The nominate race is found on the Indian subcontinent and the females of this race are the palest. The females of the Andaman Islands race andamanensis are darker, heavier-billed and shorter-tailed. The Sri Lankan race ceylonensis (formerly included with the peninsular Indian populations south of the Kaveri River) and southern nominate individuals have the females nearly identical to the males in shade. The eastern populations (Bhutan and Bangladesh) have more black on the tail and were formerly named erimelas. The populations in Burma and further south are named as the race musicus. A number of other races have been named across the range, including prosthopellus (Hong Kong), nesiotes, zacnecus, nesiarchus, masculus, pagiensis, javensis, problematicus, amoenus, adamsi, pluto, deuteronymus and mindanensis. However, many of these are not well-marked and the status of some of them is disputed. Some, like mindanensis, have now been usually recognized as full species (the Philippine magpie-robin). There is more geographic variation in the plumage of females than in that of the males. It is mostly seen close to the ground, hopping along branches or foraging in leaf-litter on the ground with a cocked tail. Males sing loudly from the top of trees or other high perches during the breeding season.

They appear stocky with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed from their dull colours when they take to flight, when the white of the wings makes them very prominent. It is very similar to the squacco heron, Ardeola ralloides, but is darker-backed. To the east of its range, it is replaced by the Chinese pond heron, Ardeola bacchus. During the breeding season, there are records of individuals with red legs. The numbers do not suggest that this is a normal change for adults during the breeding season and some have suggested the possibility of it being genetic variants. Erythristic plumage has been noted. The race phillipsi has been suggested for the populations found in the Maldives, however this is not always recognized. It forms a superspecies with the closely related Chinese pond heron, Javan pond heron and the Madagascar pond heron. They are usually silent but may make a harsh croak in alarm when flushed or near their nests. This bird was first described by Colonel W. H. Sykes in 1832 and given its scientific name in honour of John Edward Gray. Karyology studies indicate that pond herons have 68 chromosomes (2N).

The Alexandrine parakeet is one of the largest parakeets, measuring 56 to 62 cm (22 to 24 in) from the top of the head to the tip of the tail and weighing 200 to 300 g (7.1 to 10.6 oz). The tail measures 28 to 35 cm (11 to 14 in). It is predominantly green with a light blue-grey sheen on the cheeks and nape (back of the neck), yellow-green abdomen, red patch on the shoulders and massive red beak with yellow tips. The upperside of the tail passes from green at the top to blue further down, and is yellow at the tip. The underside of the tail is yellow. Adults are sexually dimorphic. Adult males have a black stripe across their lower cheeks and a pink band on their nape. Adult females lack both a black stripe across their lower cheeks and a pink band on their nape. The young are similar in appearance to adult females but have shorter tails.

Just as its name implies, the little house Sparrow socializes with humans more than any other bird species. Able to adapt and thrive in almost any habitat, excluding the extremes such as deserts and mountain peaks, this species was once restricted only to North Africa and Eurasia but now is found across the globe. Unfortunately, this opportunistic eater is not completely harmless—it can cause considerable damage to crops.

The grey-headed canary-flycatcher is about 12–13 cm (4.7–5.1 in) long with a squarish grey head, a canary yellow belly and yellowish-green upperparts. They forage actively like flycatchers and perches in a very upright posture. The sexes are indistinguishable in plumage. They have a very flat bill (which gave it the earlier genus name of Platyrhynchus) which when seen from above look like an equilateral triangle and is fringed with long rictal bristles. Across their range, populations differ in the shades of the colours and vary slightly in dimensions and several of these have been designated as subspecies. The nominate subspecies breeds in peninsular India in the hills of the Western Ghats, Nilgiris, central India and the Eastern Ghats (Lammasingi) and Sri Lanka. Subspecies calochrysea first described by Harry Oberholser in 1923 breeds along the Himalayas east to Myanmar and Thailand and winters across southern India. The nominate form is darker in shade. Subspecies antioxantha which was also described by Oberholser has a breeding range from southern Burma, Thailand through Malaysia to Java and Bali. The island population sejuncta described by Ernst Hartert in 1897 is found on Sumbawa, Flores and possibly on Lombok while connectens described by Bernhard Rensch in 1931 is restricted to the island of Sumba. The grey-headed canary-flycatcher was earlier considered to be an Old World flycatcher in spite of its odd crest, colours and nature of vocalization. Molecular phylogeny studies however show that they are quite different and have been placed in the family Stenostiridae that is closely related to the tits and penduline-tits.

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.

The great barbet has a blue head, large yellow bill, brown and green-streaked body, belly and a red vent. The plumage is green. It is the largest barbet species with a body length of 32–35 cm (13–14 in) and a weight of 192–295 g (6.8–10.4 oz).

The Himalayan black-lored tit (Machlolophus xanthogenys), also known as simply black-lored tit, is a passerine bird in the tit family Paridae. The yellow-cheeked tit is probably its closest relative, and it may also be related to the yellow tit. These three tits almost certainly form a distinct lineage, as indicated by morphology, and mtDNA cytochrome b sequence analysis (Gill et al., 2005). Lore in the bird's common name refers to the area between eye and bill. This species is a resident breeder along the Himalayas in the Indian Subcontinent. It is an active and agile feeder, taking insects and spiders from the forest canopy, and sometimes fruit. It uses woodpecker or barbet holes for nesting, and will also excavate its own hole or use man-made sites. The Himalayan black-lored tit was formerly one of the many species in the genus Parus but was moved to Machlolophus after a molecular phylogenetic analysis published in 2013 showed that the members of the new genus formed a distinct clade.

The white-throated Kingfisher is a brightly colored bird with a distinctive white throat and blue wings. It inhabits rivers, lakes, and coastal areas, and feeds on a variety of prey such as fish, frogs, and insects. The kingfisher is known for its bold, dive-bombing hunting style, diving from a perch to catch prey in the water. During the breeding season, the White-throated Kingfisher is known for its loud, cackling call. This species is widely distributed across Asia.

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.

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.
