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. Subspecies leucogenis and salangensis have a white eye-patch as do several of the island forms that breed further south. The calls are a little more... Wikipedia →

Possible
About 20% of wildlife watchers report an Ashy Drongo sighting in Manas National Park on a given day, based on 271 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 104th most-seen of the 377 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February
In that month about 30% of wildlife watchers report an Ashy Drongo in Manas National Park on a given day, against about 10% in January and March–October, the lowest months. That is one of Manas National Park's driest months, with about 40 mm of rain against 1070 mm in June.
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.
19th of 33
Of the 33 parks where we can rate Ashy Drongo sightings, Manas National Park ranks 19th at about 20%. 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 Manas National Park (genus Dicrurus, Drongos) are Black Drongo (about 50%), Bronzed Drongo (about 40%) and Hair-crested Drongo (about 40%), 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 Manas National Park (271 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.
