The white-bellied woodpecker or great black woodpecker (Dryocopus javensis) is a woodpecker species inhabiting evergreen forests in tropical Indian subcontinent and Southeast Asia. It is among the largest of the Asiatic woodpeckers and nests in large dead trees, often beside rivers. It has 14 subspecies, and many of its island forms are endangered, some are extinct. Populations differ in the distribution and extent of white. Its drums and calls are louder than those of the smaller woodpeckers.
This species is one of the largest living species of woodpecker. Adults range in size from 40 to 48 cm (16 to 19 in) and are behind only to the great slaty woodpecker and black woodpecker in size among Asian woodpecker species. The species is considered closely related to the more northern black woodpecker and the North American pileated woodpecker and is similar in size to these species. Body mass can vary from 197 to 350 g (6.9 to 12.3 oz). Among standard measurements, the wing chord is 20.5 to 25.2 cm (8.1 to 9.9 in), the tail is 14.3 to 18.9 cm (5.6 to 7.4 in), the bill is 4.6 to 6 cm (1.8 to 2.4 in) and the tarsus is 3.2 to 4.3 cm (1.3 to 1.7 in). [2]
The subspecies hodgsonii has whitish underwing coverts and a white rump. The face lacks white, but juveniles of the nominate race can have white streaks on the throat. [3] Differences from the other Southeast Asian subspecies in the vocalizations and morphology of this species are suggested to be large enough to raise this to full species status. [4] Solitary adults may spend an hour foraging at a suitable tree. [5] The subspecies hodgsonii of India breeds from January to May, mainly in large dead trees, often using the same tree year after year. [6] The normal clutch is usually of two eggs. [7] They feed mainly on insects such as ants [8] or grubs obtained mainly from under bark, but sometimes take fruit. [9] Although shy, they can nest close to well-used tracks and human disturbed areas. [6] [10] They have a range of calls from a short, sharp kuk to more intoned kyuk, kew, kee-yow calls. The longer calls are given prior to flying off. They roost within holes. [5]
Fourteen subspecies have been described:
The Andaman woodpecker (Dryocopus hodgei) was treated as a subspecies in the past. The species has in the past been placed in the genus Thriponax and Macropicus. [14]
This large black woodpecker is usually seen singly or as a pair, which may sometimes be accompanied by a third bird. They have a dipping in which the loud single note, a laugh-like chiank call, is produced. They also produce loud drumming, especially in the breeding season. The breeding season is mainly January to March. The nest is built in a large dead tree, often in open forest. Two white eggs are the usual clutch. In Bastar in central India, the squabs are sought after by tribals, resulting in the rarity of these birds there. [14]
The black woodpecker is a large woodpecker that lives in mature forests across the northern Palearctic. It is the sole representative of its genus in that region. Its range is expanding. The black woodpecker is easily the largest woodpecker species in Europe as well as in the portion of Asia where it lives and is one of the largest species worldwide. This non-migratory species tends to make its home in old-growth forest or large forest stands and excavates a large tree hole to reside in. In turn, several species rely on black woodpeckers to secondarily reside in the holes made in trees by them. This woodpeckers diet consists mostly of carpenter ants. This species is closely related to, and fills the same ecological niche in Europe as, the pileated woodpecker of North America and the lineated woodpecker of South America, also being similar to the white-bellied woodpecker which is distributed to the south somewhat of the black woodpecker in Asia.
The pileated woodpecker is a large, mostly black woodpecker native to North America. An insectivore, it inhabits deciduous forests in eastern North America, the Great Lakes, the boreal forests of Canada, and parts of the Pacific Coast. It is the largest confirmed extant woodpecker species in North America, with the possible exception of the ivory-billed woodpecker, which the U.S. Fish and Wildlife Service has proposed be reclassified as extinct. It is also the third largest species of woodpecker in the world, after the great slaty woodpecker and the black woodpecker. "Pileated" refers to the bird's prominent red crest, from the Latin pileatus meaning "capped".
The Malabar trogon is a species of bird in the trogon family. It is found in the forests of India and Sri Lanka. In India it is mainly found in the Western Ghats, hill forests of central India and in parts of the Eastern Ghats. They are insectivorous and although not migratory, may move seasonally in response to rain in hill forest regions. Like in other trogons, males and females vary in plumage. The birds utter low guttural calls that can be heard only at close quarters and the birds perch still on a branch under the forest canopy, often facing away from the viewer making them easy to miss despite their colourful plumage.
The Malabar gray hornbill is a hornbill endemic to the Western Ghats and associated hills of southern India. They have a large beak but lack the casque that is prominent in some other hornbill species. They are found mainly in dense forest and around rubber, arecanut or coffee plantations. They move around in pairs or small groups, feeding on figs and other forest fruits. Their loud cackling and laughing call makes them familiar to people living in the region.
The black-rumped flameback, also known as the lesser golden-backed woodpecker or lesser goldenback, is a woodpecker found widely distributed in the Indian subcontinent. It is one of the few woodpeckers that are seen in urban areas. It has a characteristic rattling-whinnying call and an undulating flight. It is the only golden-backed woodpecker with a black throat and a black rump.
The crimson-backed sunbird or small sunbird is a sunbird endemic to the Western Ghats of India. Like other sunbirds, they feed mainly on nectar although they take insects, especially to feed their young. They are tiny birds that are resident and are found in forests but are particularly attracted to gardens at the edge of the forest where people grow suitable flower-bearing plants. They usually perch while taking nectar.
Loten's sunbird, also known as the long-billed sunbird or maroon-breasted sunbird, is a sunbird endemic to peninsular India and Sri Lanka. Named after Joan Gideon Loten, who was the Dutch governor of colonial Ceylon, it is very similar to the purple sunbird that is found in the same areas and also tends to hover at flowers for nectar, but can be distinguished by the longer bill, the maroon band on the breast and brownish wings. Like other sunbirds, it is also insectivorous and builds characteristic hanging nests.
The yellow-browed bulbul, or golden-browed bulbul, is a species of songbird in the bulbul family, Pycnonotidae. It is found in the forests of southern India and Sri Lanka. The yellow-browed bulbul is mainly yellow on the underside and olive above with a distinct yellow brow. They are easily located by their loud calls but tend to skulk within foliage below the forest canopy. While its taxonomic classification has changed over time, it is currently the sole species within the monotypic genus Acritillas which is closely related to Hemixos.
The yellow-billed babbler is a member of the family Leiothrichidae endemic to southern India and Sri Lanka. The yellow-billed babbler is a common resident breeding bird in Sri Lanka and southern India. Its habitat is scrub, cultivation and garden land. This species, like most babblers, is not migratory, and has short rounded wings and a weak flight and is usually seen calling and foraging in groups. It is often mistaken for the jungle babbler, whose range overlaps in parts of southern India, although it has a distinctive call and tends to be found in more vegetated habitats. Its name is also confused with Turdoides leucocephala, which is also known as white-headed babbler.
The dark-fronted babbler is an Old World babbler found in the Western Ghats of India and the forests of Sri Lanka. They are small chestnut brown birds with a dark black cap, a whitish underside and pale yellow iris. They forage in flocks in the undergrowth of forests constantly making calls and uttering alarm calls when disturbed.
The greater racket-tailed drongo is a medium-sized Asian bird which is distinctive in having elongated outer tail feathers with webbing restricted to the tips. They are placed along with other drongos in the family Dicruridae. They are conspicuous in the forest habitats often perching in the open and by attracting attention with a wide range of loud calls that include perfect imitations of many other birds. One hypothesis suggested is that these vocal imitations may help in the formation of mixed-species foraging flocks, a feature seen in forest bird communities where many insect feeders forage together. These drongos will sometimes steal insect prey caught or disturbed by other foragers in the flock and another idea is that vocal mimicry helps them in diverting the attention of smaller birds to aid their piracy. They are diurnal but are active well before dawn and late at dusk. Owing to their widespread distribution and distinctive regional variation, they have become iconic examples of speciation by isolation and genetic drift.
The thick-billed flowerpecker is a tiny bird in the flowerpecker group. They feed predominantly on fruits and are active birds that are mainly seen in the tops of trees in forests. It is a resident bird with a wide distribution across tropical southern Asia from India east to Indonesia and Timor with several populations recognized as subspecies some of which are sometimes treated as full species.
The lineated woodpecker is a very large woodpecker which is a resident breeding bird from southern Mexico to northern Argentina and Trinidad in the Caribbean.
The painted bush quail is a species of quail found in the hill forests of India. They move in small coveys on hillsides and are distinguished by their red bills and legs. They have a liquid alarm call and small groups will run in single file along paths before taking flight when flushed.
The rufous woodpecker is a medium-sized brown woodpecker native to South and Southeast Asia. It is short-billed, foraging in pairs on small insects, particularly ants and termites, in scrub, evergreen, and deciduous forests and is noted for building its nest within the carton nests of arboreal ants in the genus Crematogaster. It was for sometime placed in the otherwise Neotropical genus Celeus but this has been shown to be a case of evolutionary convergence and molecular phylogenetic studies support its placement in the monotypic genus Micropternus.
The black baza is a small bird of prey found in the forests of Northeast India, the eastern Himalayas, China and Southeast Asia. Many populations are migratory, including those in the Indian region, which winter in the south of the Peninsula and Sri Lanka. Black bazas have short, stout legs and feet with strong talons, and a prominent crest. They are found in dense forest, often in small groups, and can often be found perched on bare branches of tall trees rising above the forest canopy.
The painted francolin or painted partridge is a species of francolin found in grassy areas in central and southern India and in the lowlands of southeastern Sri Lanka. They are easily detected by their loud calls especially during the breeding season. Thomas C. Jerdon noted that the species was found mainly in Central India south of the Narmada and to the east of the Western Ghats as well as the Chota Nagpur and Northern Circars. It can be confused only with the black francolin with which it partly overlaps and is said to sometimes hybridize. This species can be told apart from a black francolin female by the lack of a rufous hind collar and the white spots on the underside. The face is rufous and there is no dark stripe running behind the eye.
Tristram's woodpecker is a Korean subspecies of the white-bellied woodpecker. It was firstly identified and described by English scholar and ornithologist Henry Baker Tristram in 1879.
The heart-spotted woodpecker is a species of bird in the woodpecker family. It has a contrasting black and white plumage, a distinctively stubby body and a large wedge-shaped head making it easy to identify while its frequent calling make it easy to detect as it forage for invertebrates under the bark of the slender outer branches of trees. They move about in pairs or small groups and are often found in mixed-species foraging flocks. They have a wide distribution across Asia with populations in the forests of southwestern and central India which are slightly separated from their ranges in the Himalayas and Southeast Asia.
