White-shouldered Triller

The white-shouldered triller (Lalage sueurii) is a passerine bird belonging to the triller genus Lalage in the cuckoo-shrike family Campephagidae. It is found in Indonesia and East Timor. The white-winged triller (L. tricolor) of Australia and New Guinea was formerly included in this species but is now treated as a separate species.

It is a fairly small bird, 17 centimetres in length. The bill is grey with a black tip and the legs and feet are black. The male is mainly black above and white below. It has a grey rump, white stripe over the eye, white wing-patches and white on the outer tail-feathers. Females have a similar pattern to the males but are brown instead of black above and have fine black barring on the underparts.
