The Bornean green magpie (Cissa jefferyi) is a passerine bird in the crow family, Corvidae. It is endemic to montane forests on the southeast Asian island of Borneo. It was formerly included as a subspecies of the Javan green magpie, but under the common name Short-tailed Green Magpie. Uniquely among the green magpies, the Bornean green magpie has whitish eyes (dark reddish-brown in the other species).
It dwells in thick vegetation in the mid and upper storeys of forests, and makes only short flights. The Bornean green magpie builds an open cup nest of sticks in the canopy. The Bornean green magpie has a rather harsh call, a reminder that they are passerine birds which belong to the crow family Corvidae.

Likely
About 40% of wildlife watchers report a Bornean Green-Magpie sighting in Kinabalu Park on a given day, based on 92 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 247 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March, May and July
In those months about 60% of wildlife watchers report a Bornean Green-Magpie in Kinabalu Park on a given day, against under 5% in January and February, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Bornean Green-Magpie sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Bornean Green-Magpie sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Bornean Green-Magpie is recorded against all the birds logged in Kinabalu Park (92 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.
