The hair-crested drongo (Dicrurus hottentottus) is an Asian bird of the family Dicruridae. This species was formerly considered conspecific with Dicrurus bracteatus, for which the name "spangled drongo" – formerly used for both – is now usually reserved. Some authorities include the Sumatran drongo (D. sumatranus) in D. hottentottus as subspecies.
It is native from Pakistan, Bangladesh, India, and Bhutan through Indochina to China, Indonesia, and Brunei. Hair-crested drongos move in small flocks and are very noisy. The "spangled drongo", Dicrurus bracteatus, is native on the east coast of Australia and its name is a pejorative slang for a silly person. This may be due to its strange chattering and cackling.
In 1760, French zoologist Mathurin Jacques Brisson included a description of the hair-crested drongo in his Ornithologie based on a specimen that he mistakenly believed had been collected from the Cape of Good Hope in South Africa. He used the French name Le choucas du Cap de Bonne Espérance and the Latin Monedula Capitis Bonae Spei. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission... Wikipedia →

With luck
About 10% of wildlife watchers report a Hair-crested Drongo sighting in Hanoi on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 57th most-seen of the 97 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Hair-crested Drongo in Hanoi on a given day, against under 5% in May–August and December–March, the lowest months. That is one of Hanoi's wettest months, with about 220 mm of rain against 20 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Hair-crested 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.
11th of 30
Of the 30 cities where we can rate Hair-crested Drongo sightings, Hanoi ranks 11th at about 10%. The best odds are in Dehradun (India, about 30%), Guwahati (India, about 30%) and Tuen Mun (China, about 20%).
Same genus: Dicrurus
The closest relatives of the Hair-crested Drongo that you can see in Hanoi (genus Dicrurus, Drongos) are Ashy Drongo (about 10%) and Black Drongo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hair-crested Drongo is recorded against all the birds logged in Hanoi (14 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.
