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.

With luck
About 10% of wildlife watchers report an Ashy Drongo sighting in Hanoi on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 42nd most-seen of the 97 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
October
In that month about 40% of wildlife watchers report an Ashy Drongo in Hanoi on a given day, against under 5% in March, June and November–January, the lowest months.
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.
20th of 67
Of the 67 cities where we can rate Ashy Drongo sightings, Hanoi ranks 20th at about 10%. The best odds are in Ho Chi Minh City (Vietnam, about 40%), Bangkok (Thailand, about 30%) and Jabalpur (India, about 20%).
Same genus: Dicrurus
The closest relatives of the Ashy Drongo that you can see in Hanoi (genus Dicrurus, Drongos) are Black Drongo (about 10%) and Hair-crested Drongo (about 10%), 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 Hanoi (19 verified sightings), 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.
