Mussau Triller Lalage conjuncta

A rather long-tailed and long-winged bird with a short stubby head, similar in proportions to a small cuckooshrike. Plumage distinctively clean-cut in black and white, with mostly black upperside and white underside, broad white wing panels, and a white rump barred black. Belly often tinged with chestnut. Appears dependent on primary undisturbed forest. Often quiet, but voice reportedly includes a nasal “tchow-tchow-de-weet.”
