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 →

Rare
Under 5% of wildlife watchers report a Blyth's Hawk-Eagle sighting in Taman Negara National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 217th most-seen of the 293 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Blyth's Hawk-Eagle in Taman Negara National Park on a given day, against under 5% in October to August, the lowest months.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Blyth's Hawk-Eagle sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
4th of 7
Of the 7 parks where we can rate Blyth's Hawk-Eagle sightings, Taman Negara National Park ranks 4th at under 5%. The best odds are in Kerinci Seblat National Park (Indonesia, about 20%), Khao Luang National Park (Thailand, about 10%) and Kinabalu Park (Malaysia, about 10%).
GBIF citizen-science records
It is estimated from how often the Blyth's Hawk-Eagle is recorded against all the birds logged in Taman Negara National Park (26 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.
