Bronzed Drongo
Dicrurus aeneus
A small and compact drongo that is glossy black overall, with a short, moderately forked tail. The shiny feathers on the head, breast, and back of the neck contrast with the plain black face and belly. It often occurs in pairs and small groups, as well as in mixed-species foraging flocks. It is found in forests, along forest edges, and in well-wooded gardens and plantations. The calls are usually a pleasant jumble of shrill sounds, whistles, buzzes, and metallic notes.
识别特征
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. The young bird is duller and brownish with less spangling.<p>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.

行为
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. They sometimes join mixed-species foraging flocks. They are very good in mimicking calls of many other bird species which is a trait shared with many Drongo species. 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. These are aggressive and fearless birds, 24 cm in length, and will attack much larger species if their nest or young are threatened.
