The red-breasted partridge (Arborophila hyperythra), also known as the Bornean hill-partridge, is a species of bird in the family Phasianidae. It is endemic to hill and montane forest in Borneo, preferring bamboos and thickets. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
Richard Bowdler Sharpe described this species as Bambusicola hyperythra in 1879, from specimens collected in northwestern Borneo by William Hood Treacher, who was Acting Governor of Labuan at that time. In 1890, Sharpe described the population on Mount Kinabalu as Bambusicola erythrophrys. It was formerly considered a subspecies, but it has been suggested that the brighter plumage on the face is due to age differences. The species is currently considered monotypic.
The red-breasted partridge is about 27 cm (11 in) long and weighs about 270 g (9.5 oz). The crown and nape are blackish, with brown spots. There is a grey or rufous supercilium, and a blackish-brown band goes through the eye. The cheeks and throat are rufous. The breast is bright chestnut, sometimes browner, and the belly is whitish. The flanks are black and white... Wikipedia →

Possible
About 20% of wildlife watchers report a Red-breasted Hill Partridge sighting in Kinabalu Park on a given day, based on 546 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 247 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January, March and August
In those months about 30% of wildlife watchers report a Red-breasted Hill Partridge in Kinabalu Park on a given day, against about 20% in February, April–July and September–December, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Red-breasted Hill Partridge sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Red-breasted Hill Partridge sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Red-breasted Hill Partridge is recorded against all the birds logged in Kinabalu Park (546 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.
