Black-and-white bulbul Microtarsus melanoleucos

While highly distinctive, this bulbul can be irruptive and moves in flocks over a wide range; it is thus infrequently encountered. Both sexes are dark with white shoulder patches; female is slightly browner. Moves through lowland and foothill evergreen forest and forest edge. Forages throughout all forest levels, but most common in upper levels, where it often gathers in the crowns of fruiting trees. Occasionally gives abrupt metallic ‘ching!’
