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.
