Rare
Under 5% of wildlife watchers report a Slender-billed Oriole sighting in Royal Manas National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 349th most-seen of the 388 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Slender-billed Oriole in Royal Manas National Park on a given day, so our monthly data shows no clear season. August and September have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Slender-billed Oriole sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 3 parks where we can rate Slender-billed Oriole sightings, Royal Manas National Park ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Doi Inthanon National Park (Thailand, under 5%) and Kaeng Krachan National Park (Thailand, under 5%).
Same genus: Oriolus
The closest relatives of the Slender-billed Oriole that you can see in Royal Manas National Park (genus Oriolus, Old World Orioles) are Maroon Oriole (about 30%) and Black-hooded Oriole (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Slender-billed Oriole is recorded against all the birds logged in Royal Manas National Park (7 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.
