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. The pied triller is similar but is slightly smaller with a broader stripe above the eye and more white in the wing. The male white-winged triller has no white stripe over the eye. The song of the white-shouldered triller is a metallic whistling which is sometimes given in flight. It also utters a rapid series of harsh notes. It occurs in eastern Java , southern Sulawesi, Bali and on the Lesser Sunda Islands. It inhabits open woodland, savannas and agricultural land in dry, lowland areas. It feeds on insects, often swooping down from a perch to catch them on the ground.
