The Hair-crested Drongo (Dicrurus hottentottus) is an Asian bird of the family Dicruridae. This species was formerly considered conspecific with Dicrurus bracteatus, for which the name "Spangled Drongo" – formerly used for both – is now usually reserved. Some authorities include the Sumatran Drongo (D. sumatranus) in D. hottentottus as subspecies. It is native from India and Bhutan through Indochina to China, Indonesia, and Brunei (BirdLife International 2008). Hair-crested Drongos move in small flocks and are very noisy.
Australia's only drongo and the only Australian bird with such a deeply forked fish-like tail which it flicks in a characteristic manner upon landing. Raucous and bold - aggressive to other birds when breeding.
We had a great birding trip to Sri Lanka set up by "Best of Lanka." (www.bestoflanka.com/) We managed to get 30 of 33 endemics thanks to our guide Dhanushka (www.facebook.com/dcliyanage).
There are about 20 drongo species in the world, ranging from Africa through Iran and India through south-east Asia and Australia.
Many thanks for your visits, faves and comments. Cheers.
Spangled Drongo (revisited)
Scientific Name: Dicrurus bracteatus
Description: The Spangled Drongo has glossy black plumage, with iridescent blue-green spots (spangles), a long forked tail and blood red eyes. Sexes are similar, but the female is slightly smaller. Occasional white spotting can be seen on the upper wings of both sexes. Young birds are more sooty black without the spangles and the eye is brown. The Spangled Drongo is noisy and conspicuous, usually active, and frequently aggressive to other species.
Similar species: Several other species are glossy black with red eyes. The Metallic Starling, Aplonis metallica, (21 cm - 24 cm) is found on the north-east coast, and has black plumage, brightly glossed with green and purple, a bright red eye and long tapered tail. The Trumpet Manucode, Manucodia keraundrenii, (28 cm - 32 cm) is restricted to northern Cape York Peninsula; it has slender plumes on the nape and throat. The adult male Common Koel, Eudynamys scolopacea, (40 cm - 46 cm) is larger and lacks the spangles and fish tail.
Distribution: Spangled Drongos are found throughout northern and eastern Australia. Also found in New Guinea and eastern Indonesia. Closely related species occur through south-east Asia to India, China, and the Philippines and on some south-west Pacific islands.
Habitat: Spangled Drongos prefer wet forests, but can also be found in other woodlands, mangroves and parks. They tend to avoid more dense forest types and rainforest interiors. Birds are more common in the north, and are often seen either singly or in pairs.
Seasonal movements: migratory; Individuals from the northern areas of Western Australia and the Northern Territory migrate northwards to Indonesia, while the eastern Australian birds migrate to New Guinea. Some Drongos in the south-east and central-east, however, remain in the same area or head south, occasionally turning up in Tasmania.
Feeding: The Spangled Drongo is usually seen perched on an open branch or telegraph wire, where it awaits a passing insect. Once seen, its prey is pursued in an acrobatic display, and is caught in the drongo's slightly hooked bill. The Spangled Drongo then returns to its perch to eat its victim. The prey is guided into the bill with the assistance of sensitive, long, wire-like bristles bordering the bill (rictal bristles). Insects are also taken from foliage and from under bark; fruit and nectar also form part of its diet.
Breeding: Spangled Drongos normally have only one clutch per season. Both adults participate in building the nest, which is a simple, shallow cup of twigs, vine tendrils and grasses, held together with spider web. It is placed in a horizontal fork of tree, normally toward outer edges and up to 10 m â 20 m above the ground. Both sexes incubate the eggs and care for the young. Spangled Drongos actively defend the nest against intruders.
Calls: A variety of sounds, including some distinctive metallic notes like a stretched wire being plucked, and occasional mimicry of other bird species.

215) Drongo-Cuckoo
Square-Tailed Drongo-Cuckoo, Surniculus lugubris, Burung Hamba Kera
Found in Southeast Asia and Southern India. The calls are series of piercing sharp whistles rising in pitch but shrill and choppily delivered. It can be easily distinguished by its straight beak and the white barred vent and outer undertail, and the tail only notched with slightly flared tips. In flight a white wing-stripe is visible from below. It is a brood parasite on small babblers. It is not known how or whether the drongo-like appearance benefits this species but it is suspected that it aids in brood-parasitism just as hawk-cuckoos appear like hawks.
Burung ini seperti spesis Sewah yang lain menyerupai Drongo, mungkin kerana penyamaran apabila dia tumpang bertelur di sarang Drongo. Selalu kelihatan di pinggir hutan. Sekali imbas ia kelihatan seperti Drongo, hanya paruh dan ekornya membezakan.

The fork-tailed drongo, also called the common drongo, African drongo, or savanna drongo (Dicrurus adsimilis), is a small bird that can be found across the Afrotropical realm of continental Africa, excepting the Congolian rainforests and Upper Guinean forests. They are a passerine, part of the family, Dicruridae, with four recognized subspecies. Physically this species is characterized with a narrow fork-shaped tail, red-brownish eyes, and black plumage throughout all of his body. As an omnivorous species, its diet consists of small insects, composing of butterflies, grasshoppers and beetles, besides fruit, including those of Azadirachta indica and Moringa oleifera.
The fork-tailed drongo is known for his ability to deceptively mimic other bird alarm calls in order for a certain animal to flee the scene so he can steal their food. They are also notorious for displaying an aggressive and fearless behaviour by attacking and chasing off much larges animals, including birds of prey. When their nest or young are threatened. Due to his extensive range and stable population, the fork-tailed drongo is classified by the IUCN Red List as an least-concern species.
The fork-tailed drongo is a common and widespread resident breeder in Africa south of the Sahara. These insect-eating birds are usually found in open forests or bush, and are tolerant of arid climates. Its range was formerly considered to include Asia, but the Asian species is now called the black drongo
The fork-tailed drongo is 25 cm long and has short legs. They are medium sized and usually weigh about 50 grams. Males are mainly glossy black, although their wings are duller. Females are similar but less glossy. It is large-headed with well-developed rictal and nasal bristles, which are used as sensory organs. The rectrices curve outwards, forming the forked tail for which the species is named. The hooked bill is black and heavy, and the eye is red.
The call is a metallic strink-strink. The fork-tailed drongo uses alarm calls to steal food from birds and animals such as meerkats. They make drongo-specific calls as well as mimicked calls. The mimicked calls help them while they target other animals that are eating food. The animals flee and leave their food behind. Once they are gone, the drongo steals it. Vocal at dawn and dusk.
