Rare
Under 5% of wildlife watchers report a Green-billed Malkoha sighting in Gunung Leuser National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 149th most-seen of the 166 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
August and December
In those months about 10% of wildlife watchers report a Green-billed Malkoha in Gunung Leuser National Park on a given day, against under 5% in January–July and September–November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Green-billed Malkoha sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 18
Of the 18 parks where we can rate Green-billed Malkoha sightings, Gunung Leuser National Park ranks 18th at under 5%. The best odds are in Cat Tien National Park (Vietnam, about 50%), Khao Yai National Park (Thailand, about 40%) and Kaeng Krachan National Park (Thailand, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Green-billed Malkoha is recorded against all the birds logged in Gunung Leuser National Park (6 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.
