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.

Description

This drongo is somewhat smaller than the black drongo and has more metallic gloss with a spangled appearance on the head, neck and breast. The lores are velvety and the ear coverts are duller. The tail is slender and well forked with the outer tail feathers flaring outward slightly. Immatures have their axillaries tipped in white. [2] The young bird is duller and brownish with less spangling. [3]

The nominate race is found in India and extending until the northern part of the Malay Peninsula. Specimens from southern India are however very similar in morphometrics to those from malayensis of Burma and the size variation may be clinal. The subspecies from China kwangsiensis is treated as synonymous with aeneus. Subspecies malayensis is found from Selangor south into, Sumatra and Borneo. Taiwan is home to braunianus in the mountains of the interior. [2] [4] [5]

Distribution

The bronzed drongo is found in the Western Ghats and Eastern Ghats of India and the lower Himalayas from western Uttaranchal eastwards into Indochina and Hainan, the Malay Peninsula, Sumatra and northern Borneo. This species is usually found in moist broadleaved forest. [2] [6] This species is exclusively found in forested areas. [7]

Behaviour and ecology

They are found singly or in a group of two to three. They actively forage for insects under the forest canopy by making aerial sallies, often returning to their favourite perches. [3] They sometimes join mixed-species foraging flocks. [8] They are very good in mimicking calls of many other bird species which is a trait shared with many Drongo species. [9] The breeding season is February to July. Three or four pinkish to brownish eggs are laid in a cup nest in a tree. The eggs are darker on the broad end and often have cloudy spots. The nest is covered in cobwebs and often appears whitish. [6] These are aggressive and fearless birds, 24 cm in length, and will attack much larger species if their nest or young are threatened.

The fork-tailed drongo, also called the common drongo or African drongo, is a small bird found from the Sahel to South Africa that lives in wooded habitats, particularly woodlands and savannas. They are part of the family Dicruridae and have four recognized subspecies, D. a adsimilis, D. a. apivorus, D. a. fugax and D. a. jubaensis. Like other drongos, the fork-tailed is mostly insectivorous; its diet mainly consists of butterflies, termites, and grasshoppers.

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 black eagle is a bird of prey. Like all eagles, it is in the family Accipitridae, and is the only member of the genus Ictinaetus. They soar over forests in the hilly regions of tropical and subtropical South and Southeast Asia, as well as southeastern China. They hunt mammals and birds, particularly at their nests. They are easily identified by their widely splayed and long primary "fingers", the characteristic silhouette, slow flight and yellow ceres and legs that contrast with their dark feathers.

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 white-bellied blue flycatcher is a small passerine bird in the flycatcher family Muscicapidae. It is endemic to the Western Ghats of southwest India. Males are dark blue with a lighter shade of blue on the brow and have a greyish white belly. Females have a rufous breast, a white face and olive grey above.

<span class="mw-page-title-main">Grey-headed canary-flycatcher</span> Species of bird

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.

<span class="mw-page-title-main">Black drongo</span> Species of bird

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.

<span class="mw-page-title-main">Greater racket-tailed drongo</span> Medium sized Asian bird with elongated tail 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.
