Short-tailed Green Magpie (Cissa thalassina)

Short-tailed Green Magpie (Cissa thalassina) has been split into Javan Green Magpie C. thalassina and Bornean Green Magpie C. jefferyi.

The race Cissa jefferyi is endemic to the island of Borneo, found in foothill and true montane forest between 300 to 2,750 metres although rarely below 1,400 m elevation is dark and almost uniform apple-green with yellow wash on the forehead.The eyes are bluish-white to whitish with pale blue orbital ring and narrow red eye-ring. The black mask is broader above the eye than in nominate race, and tapers almost in a point, whereas it is flatter in C.t. thalassina. Its voice is sweet and musical with a series of 4-5 clear notes “swe-swi-swee-swi-swe-sweet” repeated after short pause with some variations. It also utters a penetrating “sweeeii” and a repeated “swe-swe-gurg” or “swe-gurg”.

The Short-tailed Green Magpie feeds mainly on snails, various insects and their larvae, small frogs, lizards, snakes, birds’ eggs and nestlings, some fruits and carrion. This species is often seen alone, in pairs or in family groups according to the season or even amongst a mixed flock of laughing thrushes, drongos and treepies. They forage in the dense undergrowth, on the ground, through shrub layers, clambering between the hanging vegetation, and sometimes reaching the upper canopy. It often feeds near the limit of the tree-line. They cross open areas from thicket to thicket, but it prefers the cover of vegetation.
