Breeding ranges of the various races according to Vaurie, note that some subspecies are no longer considered valid [2] |
The ashy drongo (Dicrurus leucophaeus) is a species of bird in the drongo family Dicruridae. It is found widely distributed across eastern and Southeast Asia, with several populations that vary in the shade of grey, migration patterns and in the size or presence of white patches around the eye.
The adult ashy drongo is mainly dark grey, and the tail is long and deeply forked, There are a number of subspecies varying in the shade of the grey plumage. Some subspecies have white markings on the head. Young birds are dull brownish grey.
Subspecies longicaudatus of India (which includes beavani of the Himalayas that winters on the peninsula, with one breeding population in central India that Vaurie separates as longicaudatus in the restricted sense) is very dark and almost like the black drongo although this bird is slimmer and has a somewhat longer and less-splayed tail. It is found in more tall forest habitat, has dark grey underside lacking the sheen of black drongo. The iris is crimson and there is no white rictal spot. Subspecies leucogenis and salangensis have a white eye-patch as do several of the island forms that breed further south. The calls are a little more nasal and twangy than that of the black drongo. [3]
The ashy drongo breeds in the hills of tropical southern Asia from eastern Afghanistan east to southern China, Ryukyu Islands in southern Japan (particularly Okinawa) and Indonesia. Many populations in the northern part of its range are migratory. Charles Vaurie described subspecies beavani (after Robert Cecil Beavan [4] ) as the population that breeds along the Himalayas that wintered in peninsular India. However, later workers include this as part of longicaudatus which also has a population that breeds in central India. [3] In winter, the species is particularly fond of hill forests. [5] E. C. Stuart Baker described stevensi which Vaurie considered as being either beavani or hopwoodi of the eastern Himalayas. To the east of the range of hopwoodi is mouhouti of Thailand and Myanmar. To the north of this range are leucogenis and salangensis (both migratory mainly to areas further south but also known from Nagaland [6] ) while bondi is found to the south. Along the southeast Asian island chain, there are number of insular populations including periophthalmus, ryukyuensis, batakensis, phaedrus, siberu and nigrescens. The nominate form is said to be found on Simalur, Java, Bali, Lombok, Palawan, and Balabac Islands. [2]
The ashy drongo has short legs and sits very upright while perched prominently, often high on a tree. It is insectivorous and forages by making aerial sallies but sometimes gleans from tree trunks. [7] They are found singly, in pairs or small groups. During migration they fly in small flocks. [5]
A common call that they make is described as drangh gip or gip-gip-drangh. [5] They can imitate the calls of other birds and are capable of imitating the whistling notes of a common iora. [8]
The breeding season is May to June with a clutch of three or four reddish or brown eggs laid in a loose cup nest in a tree. [5] [9]
The western reef heron, also called the western reef egret, is a medium-sized heron found in southern Europe, Africa and parts of Asia. It has a mainly coastal distribution and occurs in several plumage forms: a slaty-grey plumage in which it can only be confused with the rather uncommon dark morph of the Little egret ; a white form which can look very similar to the little egret although the bill tends to be paler and larger and the black form with white throat E. g. gularis of West Africa. There are also differences in size, structure and foraging behaviour. There have been suggestions that the species hybridizes with the Little Egret, and based on this, some authors treat schistacea and gularis as subspecies of Egretta garzetta. Works that consider the Western Reef Heron as a valid species include the nominate gularis and schistacea as subspecies.
The shikra is a small bird of prey in the family Accipitridae found widely distributed in Asia and Africa where it is also called the little banded goshawk. The African forms may represent a separate species but have usually been considered as subspecies of the shikra. The shikra is very similar in appearance to other sparrowhawk species including the Chinese goshawk and Eurasian sparrowhawk. They have a sharp two note call and have the typical flap and glide flight. Their calls are imitated by drongos and the common hawk-cuckoo resembles it in plumage.
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 velvet-fronted nuthatch is a small passerine bird in the nuthatch family Sittidae found in southern Asia from Nepal, India, Sri Lanka and Bangladesh east to south China and Indonesia. Like other nuthatches, it feeds on insects in the bark of trees, foraging on the trunks and branches and their strongly clawed toes allow them to climb down tree trunks or move on the undersides of horizontal branches. They are found in forests with good tree cover and are often found along with other species in mixed-species foraging flocks. Adult males can be told apart by the black stripe that runs behind and above the eyes. They have a rapid chipping call note. They breed in tree cavities and holes, often created by woodpeckers or barbets.
The Jacobin cuckoo, also pied cuckoo or pied crested cuckoo, is a member of the cuckoo order of birds that is found in Africa and Asia. It is partially migratory and in India, it has been considered a harbinger of the monsoon rains due to the timing of its arrival. It has been associated with a bird in Indian mythology and poetry, known as the chātaka represented as a bird with a beak on its head that waits for rains to quench its thirst.
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 Indian scimitar babbler is an Old World babbler. It is found in peninsular India in a range of forest habitats. They are most often detected by their distinctive calls which include an antiphonal duet by a pair of birds. They are often hard to see as they forage through dense vegetation. The long curved yellow, scimitar-shaped bills give them their name. It has been treated in the past as subspecies of the white-browed scimitar babbler which is found along the Himalayas but now separated into two species, the peninsular Indian species and the Sri Lanka scimitar babbler.
The Kashmir flycatcher is a small passerine bird in the flycatcher family Muscicapidae. It breeds in the Northwest Himalayas and winters in southern India and Sri Lanka. It was formerly considered to be a subspecies of the red-breasted flycatcher, Ficedula parva, which is its closest living relative. Males are distinctive in having a blackish border to the reddish throat while the females can easily be confused with those of F. parva.
The grey-headed canary-flycatcher, sometimes known as the grey-headed flycatcher, is a species of small flycatcher-like bird found in tropical Asia. It has a square crest, a grey hood and yellow underparts. They are found mainly in forested habitats where they often join other birds in mixed-species foraging flocks. Pairs are often seen as they forage for insects by making flycatcher-like sallies and calling aloud. Several subspecies are recognized within their wide distribution range. In the past the genus Culicicapa was considered to be an Old World flycatcher but studies have found them to belong to a new family designated as the Stenostiridae or fairy flycatchers that include the African genera Stenostira and Elminia.
The Indian blue robin is a small bird found in the Indian Subcontinent. Formerly considered a thrush, it is now considered one of the Old World flycatchers in the family Muscicapidae. It was earlier also called the Indian blue chat. It is migratory, breeding in the forests along the Himalayas of Nepal, India, Myanmar and Bangladesh. They winter in the hill forests of the Western Ghats of India and in Sri Lanka.
The black drongo is a small Asian passerine bird of the drongo family Dicruridae. It is a common resident breeder in much of tropical southern Asia from southwest Iran through Pakistan, India, Bangladesh and Sri Lanka east to southern China and Indonesia and accidental visitor of Japan. It is an all black bird with a distinctive forked tail and measures 28 cm (11 in) in length. It feeds on insects, and is common in open agricultural areas and light forest throughout its range, perching conspicuously on a bare perch or along power or telephone lines.
The white-bellied drongo is a species of drongo found across the Indian Subcontinent. Like other members of the family Dicruridae, they are insectivorous and mainly black in colour, but with a white belly and vent. Young birds are, however, all black and may be confused with the black drongo, which is smaller and more compact in appearance. The subspecies found in Sri Lanka has white restricted to the vent.
The bronzed drongo (Dicrurus aeneus) is a small Indomalayan bird belonging to the drongo group. They are resident in the forests of the Indian Subcontinent and Southeast Asia. They capture insects flying in the shade of the forest canopy by making aerial sallies from their perches. They are very similar to the other drongos of the region but are somewhat smaller and compact with differences in the fork depth and the patterns of gloss on their feathers.
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 Indian cuckoo or short-winged cuckoo is a member of the cuckoo order of birds, the Cuculiformes, that is found in the Indian subcontinent and Southeast Asia. It ranges from India, Bangladesh, Bhutan, Nepal and Sri Lanka east to Indonesia and north to China and Russia. It is a solitary and shy bird, found in forests and open woodland at up to 3,600 m (11,800 ft).
The yellow-rumped honeyguide is a sparrow-sized bird in the honeyguide family that is found in Asia, mainly in montane forests along the Himalayas. They are very finch-like but the feet are strong and zygodactyl, with two toes facing forward and two backward. They perch on honeycombs and feed on wax. Males tend to be territorial and stay near honeycombs while females and juveniles forage widely. They are brood parasites, laying their eggs in the nests of tree-hole breeders, possibly barbets.
The ashy woodswallow, sometimes also called the ashy swallow-shrike, is a woodswallow which is found in south Asia. Like other woodswallows, it has a short curved bill, a short square tail and long wings. It is usually seen perched in groups, high on powerlines, tall bare trees and most often in areas with a predominance of tall palm trees.
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 ashy minivet is a passerine bird of eastern Asia belonging to the minivet genus Pericrocotus in the cuckooshrike family Campephagidae. While most of the minivets have shades of yellow, orange and red in their plumage, this species has only greys, whites and blacks. The male is distinctive with a white face and black nape although females can be confused with the female of the brown-rumped minivet. They forage in the canopy, often along with other minivets and join mixed-species foraging flocks.
