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 →

With luck
About 10% of wildlife watchers report a Blyth's Hawk-Eagle sighting in Kinabalu Park on a given day, based on 151 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 85th most-seen of the 247 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May–August and December
In those months about 10% of wildlife watchers report a Blyth's Hawk-Eagle in Kinabalu Park on a given day, against under 5% in January–April and September–November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Blyth's Hawk-Eagle is recorded against all the birds logged in Kinabalu Park (151 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.
