Halmahera Oriole Oriolus phaeochromus

A nondescript, uniformly earth-brown medium-sized bird with a stout bill. Sexes alike. Singles and pairs can be found in the upper levels of forest, forest edge, mangroves, and nearby cultivated areas in lowlands and foothills. Sometimes joins mixed-species flocks. Differs from the similarly dark brown White-streaked Friarbird in its consistently uniform appearance, lacking any streaking or pale markings on the head. Gives a rollicking, fluty call, “ke-ke-KWEEOW.” First two notes can be barely audible, but last note powerful and loud.
