Top 20 Most Common Bird in Andaman and Nicobar Islands

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 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-whiskered Bulbul is an invasive species to North America and poses a threat to agriculture by damaging crops, outcompeting other species, and distributing non-native seeds. Otherwise, these birds can be found in lightly-wooded areas where it thrives on fruits and insects. Although it is an invasive species, native populations are believed to be on the decline.

The plume-toed swiftlet is 9–10 cm (3.5–3.9 in) in length with a square tail. The back and upper surface of the wings are uniformly dark greenish-blue with a moderate gloss. The throat and upper breast are dark grey merging into large greyish chevrons over the lower breast and flanks, usually becoming white over the belly. There is a tuft of small feathers on the hallux, the rear facing toe. This species lacks a pale contrasting rump and has no white spots on the inner webs of the tail feathers.

The red turtle dove is a relatively small species. The male has a bluish head and light red-brown body with a black ring round its neck, while the female is similar but pinkish all over.

It is a large coucal, with males being around 380–400 mm (12.6-15.7 inches) and females somewhat larger at 400–420 mm (15.7-16.5 inches) in length. Structurally, it closely resembles the greater coucal (Centropus sinensis), except that its plumage is a fawn brown as opposed to the black with bluish-purple sheen seen in C. sinensis. It has a chestnut rear mantle and wings and the head is pale tawny brown. The mantle and breast grade from pale to dark brown on the belly and vent. The iris is pale brown. The tail is a pale brown at the base and dark violet-brown towards the tip. The tail feathers have conspicuous black shafts. The juvenile shows slight barring on the body, especially on the underside.

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 white-bellied sea eagle has a white head, rump and underparts, and dark or slate-grey back and wings. In flight, the black flight feathers on the wings are easily seen when the bird is viewed from below. The large, hooked bill is a leaden blue-grey with a darker tip, and the irides are dark brown. The cere is also lead grey. The legs and feet are yellow or grey, with long black talons (claws). Unlike those of eagles of the genus Aquila, the legs are not feathered. The sexes are similar. Males are 66–80 cm (26–31 in) long and weigh 1.8–3 kg (4.0–6.6 lb). Females are slightly larger, at 80–90 cm (31–35 in) and 2.5–4.5 kg (5.5–9.9 lb). The wingspan ranges from 1.78 to 2.2 m (5.8 to 7.2 ft). A 2004 study on 37 birds from Australia and Papua New Guinea (3 °S to 50 °S) found that birds could be sexed reliably on size, and that birds from latitudes further south were larger than those from the north. There is no seasonal variation in plumage. The moulting pattern of the white-bellied sea eagle is poorly known. It appears to take longer than a year to complete, and can be interrupted and later resumed from the point of interruption. The wings are modified when gliding so that they rise from the body at an angle, but are closer to horizontal further along the wingspan. In silhouette, the comparatively long neck, head and beak stick out from the front almost as far as the tail does behind. For active flight, the white-bellied sea eagle alternates strong deep wing-beats with short periods of gliding. A young white-bellied sea eagle in its first year is predominantly brown, with pale cream-streaked plumage on their head, neck, nape and rump areas. The plumage becomes more infiltrated with white until it acquires the complete adult plumage by the fourth or fifth year. The species breeds from around six years of age onwards. The lifespan is thought to be around 30 years. The loud goose-like honking call is a familiar sound, particularly during the breeding season; pairs often honk in unison, and often carry on for some time when perched. The male's call is higher-pitched and more rapid than that of the female. Australian naturalist David Fleay observed that the call is among the loudest and furthest-carrying of all Australian bird calls, in stark contrast to the relatively quiet calls of the wedge-tailed eagle. Adult white-bellied sea eagles are unmistakable and unlikely to be confused with any other bird. Immature birds can be confused with wedge-tailed eagles. However, the plumage of the latter is darker, the tail longer, and the legs feathered. They might also be confused with the black-breasted buzzard (Hamirostra melanosternon), but this species is much smaller, has white patches on the wings, and has a more undulating flight. In India, the Egyptian vulture has white plumage, but is smaller and has a whiter back and wings. The white tail of the white-bellied sea eagle in flight distinguishes it from other species of large eagles. In the Philippines, it can be confused with the Philippine eagle, which can be distinguished by its crest; immature white-bellied sea eagles resemble immature grey-headed fish eagles, but can be identified by their more wholly dark brown underparts and flight feathers, and wedge-shaped tail.

This shrike is mainly brown on the upper parts and the tail is rounded. The black mask can be paler in winter and has a white brow over it. The underside is creamy with rufous flanks and belly. The wings are brown and lack any white "mirror" patches. Females tend to have fine scalloping on the underside and the mask is dark brown and not as well marked as in the male. The distinction is not easy to use in the field but has been tested with breeding birds in Japan where the female can be identified from the presence of a brood patch. The use of multiple measurements allows discrimination of the sex of about 90% of the birds. Subspecies lucionensis has a grey crown shading into the brown upperparts and the rump appears more rufous than the rest of the upper back. The tail is more brownish and not as reddish as in the red-backed shrike. Younger birds of lucionensis have a brown crown and lack the grey on the head. Subspecies superciliosus has a broad white supercilium and a richer reddish crown. The tail is redder and tipped in white. A number of confusing forms are known from central Asia where the populations of cristatus, isabellinus and collurio overlap. The taxonomy has been in a state of flux and some forms such as phoenicuroides formerly considered as subspecies of L. cristatus have been moved to the species L. isabellinus. Subspecies lucionensis has been recorded interbreeding with superciliosus in Ishikawa, Japan while superciliosus has interbred with Lanius tigrinus in central Japan.

While the common Sandpiper is considered a common shorebird around lakes and rivers, it does have a unique trait. The small bird bobs its tail, giving the appearance of wagging. The bird communicates with others by chirping in the air, but is silent when feeding on small crustaceans and invertebrates.

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.

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 common Moorhen is often found in slow-moving or standing-water aquatic ecosystems with dense vegetation coverage where they can hide and forage for food. If vegetation is dense enough, their large feet even enable them to walk across the floating plants. These birds are opportunistic feeders and will eat any food that is currently available.

Adult white-breasted waterhens have mainly dark grey upperparts and flanks, and a white face, neck and breast. The lower belly and undertail are cinnamon coloured. The body is flattened laterally to allow easier passage through the reeds or undergrowth. They have long toes, a short tail and a yellow bill and legs. Sexes are similar but females measure slightly smaller. Immature birds are much duller versions of the adults. The downy chicks are black, as with all rails.

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 pacific Golden-plover is a small, migratory shorebird known for its golden-brown plumage and unique, elegant flight. Found across the Pacific rim, it inhabits grasslands, marshes, and coastal areas. During the non-breeding season, it feeds on insects and invertebrates. During the breeding season, it primarily feeds on small crustaceans. This bird is a strong flier, capable of covering vast distances during migration.

A water bird, the common Redshank is wary of intrusion. It often provides a warning for other birds with its loud calls when potential threats are nearby. It is often seen in coastal and freshwater areas, feeding in the shallows. When the bird bobs its tail, it is an indication it is feeling nervous.

The collared kingfisher is 23 to 25 cm (9.1 to 9.8 in) long and the male weighs 51 to 90 g (1.8 to 3.2 oz), while the female weighs 54–100 g (1.9–3.5 oz). It varies from blue to green above while the underparts can be white or buff. There is a white collar around the neck, giving the bird its name. Some races have a white or buff stripe over the eye while others have a white spot between the eye and bill. There may be a black stripe through the eye. The large bill is black with a pale yellow base to the lower mandible. Females tend to be greener than the males. Immature birds are duller than the adults with dark scaly markings on the neck and breast. It has a variety of calls which vary geographically. The most typical call is a loud, harsh and metallic "kee-kee-kee" repeated several times.

These tall birds are quite distinctive with their bright white feathers, black legs, and orange beaks. Great Egrets live near both fresh and saltwater, nesting high in trees to protect their eggs from predatory mammals. They are colonial nesters, living in large groups (colonies), and they find the majority of their food in the nearest body of water.

This species, as its scientific name implies, is intermediate in size between the great egret and smaller white egrets like the little egret and cattle egret, though nearer to little than great. It is about 56–72 cm (22–28 in) long with a 105–115 cm (41–45 in) wingspan and weighs c. 400 g (14 oz), with all-white plumage, generally dark legs and a thickish yellow bill. Breeding birds may have a reddish or black bill, greenish yellow gape skin, loose filamentous plumes on their breast and back, and dull yellow or pink on their upper legs (regional variations). The sexes are similar.
