The maroon oriole (Oriolus traillii) is a species of bird in the family Oriolidae. It is found in Southeast Asia. The maroon oriole was originally described in the genus Pastor. Along with the black, black-and-crimson and silver orioles, it belongs to a clade of red and black orioles.
Four subspecies are recognised: The silver oriole of southern China was originally described by Stresemann as another subspecies of maroon oriole, but is now treated as a separate species; it is very similar, except that the red in the body plumage of the maroon oriole is replaced by silvery white. Genetic evidence has now shown that Stresemann's original assessment was accurate, with silver oriole genetically embedded among the subspecies of maroon oriole; the nominate subspecies of maroon oriole is more closely related to silver oriole, than it is to any of the other maroon oriole subspecies.

Rare
Under 5% of wildlife watchers report a Maroon Oriole sighting in Kathmandu on a given day, based on 107 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 312 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
March–April and June
In those months about 10% of wildlife watchers report a Maroon Oriole in Kathmandu on a given day, against under 5% in May and July–February, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Maroon Oriole sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Among the best
Of the 3 cities where we can rate Maroon Oriole sightings, Kathmandu ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Dehradun (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Maroon Oriole is recorded against all the birds logged in Kathmandu (107 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.
