The black-naped oriole (Oriolus chinensis) is a passerine bird in the oriole family that is found in many parts of Asia. There are several distinctive populations within the wide distribution range of this species and in the past the slender-billed oriole (Oriolus tenuirostris) was included as a subspecies. Unlike the Indian golden oriole which only has a short and narrow eye-stripe, the black-naped oriole has the stripe broadening and joining at the back of the neck. Males and females are very similar although the wing lining of the female is more greenish. The bill is pink and is stouter than in the golden oriole.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the black-naped oriole in his Ornithologie based on a specimen that he mistakenly believed had been collected in the former French colony of Cochinchina in what is now southern Vietnam. He used the French name Le loriot de la Cochinchine and the Latin Oriolus Cochinsinensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature.

With luck
About 10% of wildlife watchers report a Black-naped Oriole sighting in Kolkata on a given day, based on 1,117 verified sightings from GBIF citizen-science data. It is the 57th most-seen of the 247 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
February–April and October–November
In those months about 20% of wildlife watchers report a Black-naped Oriole in Kolkata on a given day, against under 5% in May to September, the lowest months. Those are among Kolkata's driest months, with about 55 mm of rain a month against 330 mm in July.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Black-naped Oriole sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
18th of 50
Of the 50 cities where we can rate Black-naped Oriole sightings, Kolkata ranks 18th at about 10%. The best odds are in Singapore (Singapore, about 70%), Kuala Lumpur (Malaysia, about 60%) and Manila (Philippines, about 50%).
Same genus: Oriolus
The closest relatives of the Black-naped Oriole that you can see in Kolkata (genus Oriolus, Old World Orioles) are Black-hooded Oriole (about 50%) and Indian Golden Oriole (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-naped Oriole is recorded against all the birds logged in Kolkata (1,117 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.
