About Dendrocitta cinerascens Sharpe, 1879
This fairly large bird reaches 40 centimeters in total length, with a long graduated tail, broad rounded wings, and short weak legs. Its underparts are pinkish-brown, matching the color of most of its head, which additionally has a pale silver crown and a dark stripe running over the eye and across the forehead. Its back is greyish, and its rump is pale. The wings are black with a white patch, and the grey tail feathers have black tips. The bill and legs are grey-black, and the eyes are reddish. This species differs from the Sumatran treepie, which has a pale brown back, dark brown head, white nape, and thinner bill. The Bornean treepie is a noisy bird that produces a range of loud, explosive calls. These calls include a bell-like whistle, along with various grunting and chattering calls, and the species can mimic the calls of other birds. It is fairly common across most mountain ranges in northern and central Borneo. It mainly lives at elevations between 300 and 2,800 meters above sea level, and is most common in valleys and foothills at the lower end of this elevation range. It inhabits forest, forest edge, bamboo thickets, and scrubland, and is sometimes spotted in cultivated areas. It forages in the tree canopy alone or in small groups, searching for small fruit, seeds, and large insects such as beetles and cockroaches. It can become tame, and will visit villages to feed on food scraps. Little is known about its breeding habits. The species builds a shallow nest constructed from fine twigs, placed in a low tree. Its eggs are greenish-white with brown markings that form a concentrated ring around the wider end of the egg.
