Young birds are, however, all black and may be confused with the black drongo, which is smaller and more compact in appearance. The subspecies found in Sri Lanka has white restricted to the vent.
In 1747 the English naturalist George Edwards included an illustration and a description of the white-bellied drongo in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Fork- tail'd Indian Butcher-Bird". Edwards based his hand-coloured etching on a specimen that had been sent from Bengal to the silk-pattern designer Joseph Dandridge in London. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the white-bellied drongo with the shrikes in the genus Lanius. Linnaeus included a brief description, coined the binomial name Lanius caerulescens and cited Edwards' work. The specific epithet caerulescens is Latin meaning "bluish". The white-bellied...

Rare
Under 5% of wildlife watchers report a White-bellied Drongo sighting in Coimbatore on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 197th most-seen of the 201 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-bellied Drongo in Coimbatore on a given day, so our monthly data shows no clear season.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most White-bellied 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.
15th of 17
Of the 17 cities where we can rate White-bellied Drongo sightings, Coimbatore ranks 15th at under 5%. The best odds are in Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 50%), Jaipur (India, about 20%) and Lucknow (India, about 10%).
GBIF citizen-science records
It is estimated from how often the White-bellied Drongo is recorded against all the birds logged in Coimbatore (7 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.
