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.
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.
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... Wikipedia →
Rare
Under 5% of wildlife watchers report a Bronzed Drongo sighting in Gunung Leuser National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 136th most-seen of the 166 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and November–December
In those months about 10% of wildlife watchers report a Bronzed Drongo in Gunung Leuser National Park on a given day, against under 5% in January–April and June–October, the lowest months.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Bronzed Drongo sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
23rd of 28
Of the 28 parks where we can rate Bronzed Drongo sightings, Gunung Leuser National Park ranks 23rd at under 5%. The best odds are in Cat Tien National Park (Vietnam, about 60%), Royal Manas National Park (Bhutan, about 60%) and Namdapha National Park (India, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Bronzed Drongo is recorded against all the birds logged in Gunung Leuser National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
