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.

Likely
About 40% of wildlife watchers report an Ashy Drongo sighting in Royal Manas National Park on a given day, based on 485 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 388 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
December
In that month about 60% of wildlife watchers report an Ashy Drongo in Royal Manas National Park on a given day, against about 10% in January, the lowest month. That is one of Royal Manas National Park's driest months, with about 10 mm of rain against 930 mm in July. August and September have too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Ashy Drongo sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
7th of 33
Of the 33 parks where we can rate Ashy Drongo sightings, Royal Manas National Park ranks 7th at about 40%. The best odds are in Cat Tien National Park (Vietnam, about 70%), Kinabalu Park (Malaysia, about 50%) and Kaeng Krachan National Park (Thailand, about 50%). All parks ranked.
Same genus: Dicrurus
The closest relatives of the Ashy Drongo that you can see in Royal Manas National Park (genus Dicrurus, Drongos) are Bronzed Drongo (about 60%), Hair-crested Drongo (about 20%) and Greater Racket-tailed Drongo (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ashy Drongo is recorded against all the birds logged in Royal Manas National Park (485 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.
