Top 20 Most Common Bird in Kerala

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 brahminy kite is distinctive and contrastingly coloured, with chestnut plumage except for the white head and breast and black wing tips. The juveniles are browner, but can be distinguished from both the resident and migratory races of black kites in Asia by the paler appearance, shorter wings, and rounded tail. The pale patch on the underwing carpal region is of a squarish shape and separated from Buteo buzzards. The brahminy kite is about the same size as the black kite (Milvus migrans) and has a typical kite flight, with wings angled, but its tail is rounded unlike the Milvus species, red kite, and black kite, which have forked tails. The two genera are, however, very close. The call is a mewing keeyew.

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 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 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.

This is a large species of cuckoo. The head is black, upper mantle and underside are black glossed with purple. The back and wings are chestnut brown. There are no pale shaft streaks on the coverts. The eyes are ruby red. Juveniles are duller black with spots on the crown and there are whitish bars on the underside and tail. There are several geographic races and some of these populations are sometimes treated as full species.

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.

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 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.

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 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 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 sexes are alike and the main colour of the body is cinnamon with a black head and the long graduated tail is bluish grey and is tipped in black. The wing has a white patch. The only confusable species is the grey treepie which however lacks the bright rufous mantle. The bill is stout with a hooked tip. The underparts and lower back are a warm tawny-brown to orange-brown in colour with white wing coverts and black primaries. The bill, legs and feet are black.

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).

Purple-rumped sunbirds are tiny at less than 10 cm long. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations for nectar feeding. Purple-rumped sunbirds are sexually dimorphic. The males have a dark maroon upperside with a blue-green crown that glistens at some angles, bright green shoulder patch and violet/purple rump patch which is generally hidden under the wings. The underparts are whitish with dark throat, maroon breast band and purple/violet patch in the throat which is visible in some angles. The iris is generally reddish in color. In the Western Ghats, it can overlap in some areas with the crimson-backed sunbird but the male of that species has reddish upperparts, a broader breast band and generally darker eyes. The female has a white throat followed by yellowish breast. The upperside is olive or brownish. The uppertail coverts are black and a weak supercilium may be visible. The nominate subspecies from Sri Lanka has a more bluish violet throat whereas the Indian form flaviventris (two other proposed populations whistleri from Maddur in Karnataka and sola from Pondicherry are subsumed) has a more pinkish tinge. Their call is ptsiee ptsit, ptsiee ptsswit or a sharp twittering tityou, titou, trrrtit, tityou....

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 black-rumped flameback is a large species at 26–29 cm in length. It has a typical woodpecker shape, and the golden yellow wing coverts are distinctive. The rump is black and not red as in the greater flameback. The underparts are white with dark chevron markings. The black throat finely marked with white immediately separates it from other golden backed woodpeckers in the Indian region. The head is whitish with a black nape and throat, and there is a greyish eye patch. Unlike the greater flameback it has no dark moustachial stripes. The adult male has a red crown and crest. Females have a black forecrown spotted with white, with red only on the rear crest. Young birds are like the female, but duller. Like other woodpeckers, this species has a straight pointed bill, a stiff tail to provide support against tree trunks, and zygodactyl feet, with two toes pointing forward, and two backward. The long tongue can be darted forward to capture insects. The black-rumped flameback is the only golden-backed woodpecker with both a black throat and a black rump. Leucistic birds have been recorded. Two specimens of male birds from the northern Western Ghats have been noted to have red-tipped feathers on the malar region almost forming a malar stripe. A female specimen from Lucknow has been noted to have grown an abnormal downcurved hoopoe-like bill.

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.
