Possible
About 30% of wildlife watchers report a Green-tailed Sunbird sighting in Langtang National Park on a given day, based on 149 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 225 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.
July
In that month about 50% of wildlife watchers report a Green-tailed Sunbird in Langtang National Park on a given day, against about 20% in June, August, October and December, the lowest months. That is one of Langtang National Park's wettest months, with about 390 mm of rain against 10 mm in November.
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.
2nd of 4
Of the 4 parks where we can rate Green-tailed Sunbird sightings, Langtang National Park ranks 2nd at about 30%. The best odds are in Doi Inthanon National Park (Thailand, about 50%).
GBIF citizen-science records
It is estimated from how often the Green-tailed Sunbird is recorded against all the birds logged in Langtang National Park (149 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.
