Loriot de Buru Oriolus bouroensis

A large gray-brown oriole with a straight, heavy bill. Main field mark is an ill-defined dark mask on the feathered face. Underparts paler than upperside. Juveniles display rufous-edged wings. Singles or pairs can be found in forest, forest edge, mangroves, and woodlands in lowlands and foothills. Similar to Buru Friarbird, but dark facial area is feathered, not bare; bill shape is thick and straight; and tail is shorter. Variable song consists of around three fluty notes, often rising and loudest on final note: “ku-wuWOOO.”
