The black-hooded oriole (Oriolus xanthornus) is a member of the oriole family of passerine birds and is a resident breeder in tropical southern Asia from India and Sri Lanka east to Indonesia. It is a bird of open woodland and cultivation. The nest is built in a tree, and contains two eggs. Its food is insects and fruit, especially figs, found in the tree canopies where they spend much of their time.
The black-hooded oriole was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Coracias xanthornus. Linnaeus was confused by the similar appearance of the unrelated New World orioles and the Old World orioles. In his entry for Coracias xanthornus he cited descriptions of birds occurring in Jamaica by Mark Catesby and Patrick Browne as well as an illustration by George Edwards of a bird occurring in Bengal. Linnaeus specified the habitat as "America" but Bengal is now the recognised type location. Also in the 10th edition Linnaeus listed Sturnus luteolus among the starlings and cited another illustration by Edwards. He renamed this species as Oriolus melanocephalus in the 12th... Wikipedia →

Possible
About 30% of wildlife watchers report a Black-hooded Oriole sighting in Chattogram on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 26th most-seen of the 76 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January
In that month about 50% of wildlife watchers report a Black-hooded Oriole in Chattogram on a given day, against about 20% in February, June and December, the lowest months. That is one of Chattogram's driest months, with about 10 mm of rain against 780 mm in July. April and July–August have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-hooded Oriole sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
15th of 37
Of the 37 cities where we can rate Black-hooded Oriole sightings, Chattogram ranks 15th at about 30%. The best odds are in Savar (Bangladesh, about 80%), Asansol (India, about 80%) and Bhubaneshwar (India, about 70%).
Same order: Passeriformes
The closest relatives of the Black-hooded Oriole that you can see in Chattogram (order Passeriformes, Perching Birds) are Indian Pied Starling (about 80%), House Crow (about 70%) and Striated Grassbird (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-hooded Oriole is recorded against all the birds logged in Chattogram (23 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.
