Piping Bellbird

A small, active, mostly dull olive-green and gray warbler-like bird with a white eye-ring that is obvious with a good view. An uncommon resident in the forest canopy of interior Príncipe, where small groups join mixed-species flocks. A dry, reedy chittering contact call is often the first sign of their presence. Principe White-eye may join the same flocks as Principe Speirops, which is slightly larger and has a much whiter head.

A fairly large bird of lowland and foothill forest on Panay and Negros islands. Small for a hornbill. Bill fairly short with black bands. Has black wings, a pale buffy tail with black tip, and bare skin around the eye and chin with a blue tinge. Male has pale underparts and head with a black cheek, while female is entirely black. Male is unmistakable in range. Female is similar to female Writhe-billed Hornbill, but smaller, and lacks the red bill. Voice is a short, medium-pitched honk, reminiscent of a squeaky toy.

A medium-sized night bird of forest and open areas from the lowlands to the mountains. Heavily patterned in various shades of brown, with finely barred underparts, blotching on the chest, and dark wings with large pinkish and white spots and a broad pale bar bordered with black. Note the white lines on the side of the throat with a black line below, and the broad white band on the end of the undertail. Voice is a distinctive, loud two-noted “pyok prraw,” the second note slightly lower and with a vibrating quality.
