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 Sok National Park on a given day, based on 102 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 74th most-seen of the 213 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Wallace's Hawk-Eagle is recorded against all the birds logged in Khao Sok National Park (102 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.
