Likely
About 50% of wildlife watchers report a Green-tailed Sunbird sighting in Doi Inthanon National Park on a given day, based on 1,817 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 367 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
May, July and September–October
In those months about 60% of wildlife watchers report a Green-tailed Sunbird in Doi Inthanon National Park on a given day, against about 50% in June, August and November–April, the lowest months. Those are among Doi Inthanon National Park's wettest months, with about 290 mm of rain a month against 20 mm in February.
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.
Yes
Of the 4 parks where we can rate Green-tailed Sunbird sightings, Doi Inthanon National Park has the highest daily chance: about 50%. Next come Langtang National Park (Nepal, about 30%) and Royal Manas National Park (Bhutan, about 10%).
Same genus: Aethopyga
The closest relatives of the Green-tailed Sunbird that you can see in Doi Inthanon National Park (genus Aethopyga, Red Sunbirds and Allies) are Mrs Gould's Sunbird (about 40%) and Black-throated Sunbird (about 40%), 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 Doi Inthanon National Park (1,817 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.
