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 →

GBIF citizen-science records
It is estimated from how often the Wallace's Hawk-Eagle is recorded against all the birds logged in Sepilok (1,339 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.
