Yellow-billed Grosbeak

Spectacular male shows diagnostic maroon sides to head and collar, iridescent metallic blue-green forehead and crown, blue shoulder, moss-green back, and yellow rump. Underside is uniform bright yellow in both sexes, although female is entirely olive above. Juvenile resembles female but with pale legs. Singles and pairs inhabit forest, shrubbery, and plantations in lowlands and lower hills, often joining mixed-species flocks. Female can be separated from female Black and Brown-throated Sunbirds by bright yellow underparts and lack of yellow eyebrow. Gives high-pitched “tzeeet” calls. Song is an undulating trill.

A medium-sized, fairly small bird of lowland and foothill forest interior. Black upperparts, head and marks on the sides of the chest, underparts white up to the bill, thin white eye-brow, wedge below the eye and patch in the wing. Shy and difficult to see. Very similar to Black- chinned Robin and co-occurs in some areas, but Black-sided has black on the sides of the chest, and has a narrower white eyebrow. Heard more often than seen. Voice, a distinctive “wee-chow!”, the second note with an explosive quality.

Immense and imposing owl of dense wet lowland and hill forests. Silver-gray adult is majestic, with a large yellow bill, black eyes, and sweeping sidewards-facing “horns.” Juvenile is much paler, almost white, with shorter tufts. Gives deep echoing hoots. Primarily nocturnal, but will on occasion hunt by day; takes prey as large as small deer.
