Yellow-bellied Whistler Pachycephala philippinensis

A fairly small bird of lowland and foothill forest. Brown above and yellow below with a white throat. Races differ, with southern birds having more yellowish upperparts. Somewhat similar to Mindanao White-eye, but has a slightly thicker bill, lacks the olive-green back, and is usually found at lower elevations. Calls include a fairly high-pitched downslurred whistle. Song consists of a short phrase of slurred whistles.
