Blyth's hawk-eagle (Nisaetus alboniger) (earlier treated as Spizaetus) is a medium-sized bird of prey. Like all eagles, it is in the family Accipitridae. It can be found in the Malay Peninsula, Singapore, Sumatra and Borneo. It is a bird of open woodland, although island forms prefer a higher tree density. It builds a stick nest in a tree and lays a single egg.
It is a fairly small eagle at about 50–60 cm (20–24 in) in length. The adult has a thick white band on uppertail and undertail, all black above, black spotted breast, barred below. It has a prominent crest like the bazas. Juvenile is dark brown above, and has a light brown head and underparts.
The common name commemorates Edward Blyth (1810–1873), English zoologist and Curator of the Museum of the Asiatic Society of Bengal. BirdLife Species Factsheet Wikipedia →

GBIF citizen-science records
It is estimated from how often the Blyth's Hawk-Eagle is recorded against all the birds logged in Khao Luang National Park (62 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.
