has mainly dully glossed black plumage except for a white lower belly and undertail. It has a white iris and yellow lower mandible. The sexes are alike, but the juvenile has unglossed plumage, a brown iris and a dull yellow lower mandible. There are no subspecies. This species has a number of calls, but the most familiar is a ''skeer kerrra kerrra''. There is also a soft warbling song.

Behaviour

Breeding

The pied starling usually nests in tunnels in river banks, but will use holes in buildings, straw bales or natural tree holes. There is a record of a nest being constructed in a wrecked ship from the shore. The nest is lined with a wide variety of plant material and items of human waste such as paper and rope. The female typically lays four eggs, though clutches of two to six are known. The eggs are blue-green, immaculate or with some red spots. The female alone incubates for , and the chicks fledge in another . Both parents feed the chicks, assisted by helpers, which are typically subadult or unmated birds. This cooperative breeding is reinforced by mutual allofeeding between adults, behaviour reinforced by the bright
