Sumatran laughingthrush
The Sumatran laughingthrush ("Garrulax bicolor"), also known as the black-and-white laughingthrush, is a member of the family Leiothrichidae. It is endemic to highland forest on the Indonesian island of Sumatra, where it is threatened by habitat loss and capture for the domestic wildlife trade . It was formerly treated as a subspecies of the white-crested laughingthrush ("G. leucolophus"), but unlike that species the plumage of the Sumatran laughingthrush is blackish-brown and white.
