Wallace's hawk-eagle (Nisaetus nanus) is a species of bird of prey in the family Accipitridae. It is found in Kra Isthmus, Malay Peninsula, Sumatra and Borneo. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss and trade. It is among the smallest eagles in the world at about 46 cm (18 in) long and weighing 500–610 g (1.10–1.34 lb) (about the size of a peregrine falcon).
It is named after Alfred Russel Wallace, a British naturalist, explorer, geographer, anthropologist and biologist. It is non-migratory. Wikipedia →

With luck
About 10% of wildlife watchers report a Wallace's Hawk-Eagle sighting in Khao Luang National Park on a given day, based on 55 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 130th most-seen of the 215 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February and July
In those months about 20% of wildlife watchers report a Wallace's Hawk-Eagle in Khao Luang National Park on a given day, against under 5% in May, August–September and November–December, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Wallace's Hawk-Eagle sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
5th of 5
Of the 5 parks where we can rate Wallace's Hawk-Eagle sightings, Khao Luang National Park ranks 5th at about 10%. The best odds are in Kinabatangan Wildlife Sanctuary (Malaysia, about 50%), Sepilok (Malaysia, about 50%) and Danum Valley Conservation Area (Malaysia, about 20%).
GBIF citizen-science records
It is estimated from how often the Wallace's Hawk-Eagle is recorded against all the birds logged in Khao Luang National Park (55 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.
