The black drongo (Dicrurus macrocercus) is a small Asian passerine bird of the drongo family Dicruridae. It is a common resident breeder in much of tropical southern Asia from southwest Iran through Pakistan, India, Bangladesh and Sri Lanka east to southern China and Indonesia and accidental visitor of Japan. It is an all black bird with a distinctive forked tail and measures 28 cm (11 in) in length. It feeds on insects, and is common in open agricultural areas and light forest throughout its range, perching conspicuously on a bare perch or along power or telephone lines.
The species is known for its aggressive behaviour towards much larger birds, such as crows, never hesitating to dive-bomb any bird of prey that invades its territory. This behaviour earns it the informal name of king crow. Smaller birds often nest in the well-guarded vicinity of a nesting black drongo. Previously grouped along with the African fork-tailed drongo (Dicrurus adsimilis), the Asian forms are now treated as a separate species with several distinct populations.
The black drongo is listed as least concern by the International Union for Conservation of Nature (IUCN) on the IUCN Red List, due to its large range and relative commonness. It has been introduced to some Pacific islands, where it has thrived and become abundant to the point of threatening and causing the extinction of native and endemic bird species there. Wikipedia →

Likely
About 50% of wildlife watchers report a Black Drongo sighting in Gir National Park on a given day, based on 104 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 135 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
April
In that month about 70% of wildlife watchers report a Black Drongo in Gir National Park on a given day, against about 40% in May–June and September, the lowest months. That is one of Gir National Park's driest months, with almost no rain against 330 mm in July. July and August have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black Drongo sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
10th of 31
Of the 31 parks where we can rate Black Drongo sightings, Gir National Park ranks 10th at about 50%. The best odds are in Kanha National Park (India, about 70%), Keoladeo National Park (India, about 70%) and Chitwan National Park (Nepal, about 70%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Black Drongo is recorded against all the birds logged in Gir National Park (104 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.
