Top 20 Most Common Bird in West Bengal

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 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 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 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.

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).

This myna is strikingly marked in black and white and has a yellowish bill with a reddish bill base. The bare skin around the eye is reddish. The upper body, throat and breast are black while the cheek, lores, wing coverts and rump are contrastingly white. The sexes are similar in plumage but young birds have dark brown in place of black. The subspecies vary slightly in plumage, extent of streaking of the feathers and in measurements. The flight is slow and butterfly-like on round wings. Leucistic individuals have been recorded.

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 little cormorant is about 50 centimetres (20 in) long and only slightly smaller than the Indian cormorant (Phalacrocorax fuscicollis). The Indian cormorant has a narrower and longer bill which ends in a prominent hook tip, blue iris and a more pointed head profile. The breeding adult bird has a glistening all black plumage with some white spots and filoplumes on the face. There is also a short crest on the back of the head. The eyes, gular skin and face are dark. In the non-breeding bird or juvenile, the plumage is brownish and the bill and gular skin can appear more fleshy. The crest becomes inconspicuous and a small and well-marked white patch on the throat is sometimes visible. Towards the west of the Indus River valley, its range can overlap with vagrant pygmy cormorants (Microcarbo pygmaeus), which can be difficult to differentiate in the field and are sometimes even considered conspecific. The sexes are indistinguishable in the field, but males tend to be larger. Some abnormal silvery-grey plumages have been described. The species was described by Vieillot in 1817 as Hydrocorax niger. The genus Hydrocorax literally means water crow. It was later included with the other cormorants in the genus Phalacrocorax but some studies place the smaller "microcormorants" under the genus Microcarbo.

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 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.

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 Eudynamys scolopaceus is commonly called asian Koel, native to China, the Indian Subcontinent and parts of Southeast Asia. This bird is used widely in Indian poetry, and it has a habit of colonizing new areas that it goes to. The bird is also known for stealing nests from other birds and having their chicks raised by the foster parents.

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 Asian openbill stork is predominantly greyish (non-breeding season) or white (breeding season) with glossy black wings and tail that have a green or purple sheen. The name is derived from the distinctive gap formed between the recurved lower and arched upper mandible of the beak in adult birds. Young birds do not have this gap. The cutting edges of the mandible have a fine brush like structure that is thought to give them better grip on the shells of snails. The tail consists of twelve feathers and the preen gland has a tuft. The mantle is black and the bill is horn-grey. At a distance, they can appear somewhat like a white stork or Oriental stork. The short legs are pinkish to grey, reddish prior to breeding. Non-breeding birds have a smoky grey wings and back instead of white. Young birds are brownish-grey and have a brownish mantle. Like other storks, the Asian openbill is a broad-winged soaring bird, which relies on moving between thermals of hot air for sustained flight. They are usually found in flocks but single birds are not uncommon. Like all storks, it flies with its neck outstretched. It is relatively small for a stork and stands at 68 cm height (81 cm long).

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.

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.

The Asian palm swift (Cypsiurus balasiensis) is a small swift. It is very similar to the African palm swift, Cypsiurus parvus, and was formerly considered to be the same species. It is a common resident breeder in tropical Asia from India to the Philippines. The down and feather nest is glued to the underside of a palm leaf with saliva, which is also used to secure the usually two or three eggs. This is a bird of open country and cultivation, which is strongly associated with oil palms. This 13 cm long species is mainly pale brown in colour. It has long swept-back wings that resemble a crescent or a boomerang. The body is slender, and the tail is long and deeply forked, although it is usually held closed. The call is a loud shrill scream. Sexes are similar, and young birds differ from adults mainly in their shorter tails. Asian palm swift has very short legs which it uses only for clinging to vertical surfaces, since swifts never settle voluntarily on the ground. These swifts spend most of their lives in the air, living on the insects they catch in their beaks. Asian palm swifts often feed near the ground, and they drink on the wing.

The male is striking, with the typical oriole black and yellow colouration. The plumage is predominantly yellow, with a solid black hood, and black also in the wings and tail centre. The female black-hooded oriole is a drabber bird with greenish underparts, but still has the black hood. Young birds are like the female, but have dark streaking on the underparts, and their hood is not solidly black, especially on the throat. The black head of this species is an obvious distinction from the Indian golden oriole, which is a summer visitor to northern India. Orioles can be shy, and even the male may be difficult to see in the dappled yellow and green leaves of the canopy. The black-hooded oriole's flight is somewhat like a thrush, strong and direct with some shallow dips over longer distances. While foraging the species uses foliage-gleening, wood-gleening, or sallying methods.

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.

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.
