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 Thrissur on a given day, based on 539 verified sightings from GBIF citizen-science data. It is the 59th most-seen of the 217 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report an Ashy Drongo in Thrissur on a given day, against under 5% in March and May–August, the lowest months. That is one of Thrissur's driest months, with about 30 mm of rain against 440 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.
7th of 67
Of the 67 cities where we can rate Ashy Drongo sightings, Thrissur ranks 7th at about 20%. 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 Thrissur (genus Dicrurus, Drongos) are Black Drongo (about 70%), Greater Racket-tailed Drongo (about 50%) and Bronzed 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 Thrissur (539 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.
