The Black-winged Starling (Acridotheres melanopterus) is a species of starling in the family Sturnidae. The species is also known as the Black-winged Myna or the White-breasted Starling. It is endemic to Indonesia. There are three recognised subspecies: the nominate race, which occurs across much of the island of Java; tricolor, which is restricted to south east Java; and tertius, which is found on Bali and possibly Lombok. The validity of the records on Lombok has been called into question, as there are only a few records and those may represent escapees from the caged-bird trade or natural vagrants. The species has often been assigned to the starling genus Sturnus, but is now placed in Acridotheres because it is behaviourally and vocally closer to the birds in that genus.[3]

The Black-winged Myna is a small myna, 23 centimetres (9.1 in) in length. The plumage of this species is striking, with the head, breast, back and rump being white, and the tail and parts of the wings glossy black. The tip of the tail and parts of the wings are also white. The skin around the eye is unfeathered and yellow. The bill is yellow, and slightly darker towards the base. The sexes are alike, and young birds are like the adults except that juveniles' crown and back are grey. The subspecies tricolor is similar to the nominate but has a grey back and much more black on the wings. The subspecies tertius is similar to tricolor except the grey on the back descends to the tail.[3]
