Isabela Oriole Oriolus isabellae

A medium-sized bird of lowland forest, including secondary habitats and bamboo in northern Luzon. Yellow underparts blend into olive upperparts. Bill fairly long and silver. Forages for fruit and insects, sometimes in mixed-species flocks. Similar to White-lored Oriole, but slightly larger, with a silver rather than red bill and no white spot in front of the eye. Song consists of a medium-pitched, upslurred whistle, “hoowit!”.
