With luck
About 10% of wildlife watchers report a Green-tailed Sunbird sighting in Royal Manas National Park on a given day, based on 125 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 150th most-seen of the 388 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Green-tailed Sunbird in Royal Manas National Park on a given day, against under 5% in June, the lowest month. That is one of Royal Manas National Park's driest months, with about 10 mm of rain against 930 mm in July. August and September have too few records to rate.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Green-tailed Sunbird 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.
3rd of 4
Of the 4 parks where we can rate Green-tailed Sunbird sightings, Royal Manas National Park ranks 3rd at about 10%. The best odds are in Doi Inthanon National Park (Thailand, about 50%) and Langtang National Park (Nepal, about 30%).
Same genus: Aethopyga
The closest relatives of the Green-tailed Sunbird that you can see in Royal Manas National Park (genus Aethopyga, Red Sunbirds and Allies) are Black-throated Sunbird (about 30%) and Crimson Sunbird (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green-tailed Sunbird is recorded against all the birds logged in Royal Manas National Park (125 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.
