The mountain serpent eagle (Spilornis kinabaluensis), also known as the Kinabalu serpent eagle, is a bird of prey that is found in northern Borneo. It is found at altitudes of 1,000–4,100 metres (3,300–13,500 ft) in forest, especially where it becomes stunted. Where their range overlaps, the crested serpent eagle generally occurs at lower altitudes. The mountain serpent eagle is darker than the Bornean subspecies of the crested serpent eagle.
The mountain serpent eagle is threatened by habitat loss. However, they occur within the Kinabalu National Park and the Gunung Mulu National Park. Their high-altitude habitats are usually too remote for logging and agriculture, making some of its range secure.

With luck
About 10% of wildlife watchers report a Mountain Serpent-Eagle sighting in Kinabalu Park on a given day, based on 247 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 247 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Mountain Serpent-Eagle in Kinabalu Park on a given day, against under 5% in July, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Mountain Serpent-Eagle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Mountain Serpent-Eagle sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mountain Serpent-Eagle is recorded against all the birds logged in Kinabalu Park (247 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.
