White-tailed Warbler
Poliolais lopezi
Males appear overall gray, with a darker back and cap and a paler belly and throat. Females are similar but with reddish tones to the head. All individuals have extremely short tails with bright white outer tail feathers. An easily overlooked, diminutive warbler of montane forests, where it is often found in shaded thickets. Calls include a typewriter-like trill and nasal “nya nya nya” calls. Birds will sometimes duet, with the female giving nasal calls and the male giving clear, often paired whistles. Birds on Bioko also give a whistled “wheet” that rises in pitch.

Gray-hooded Gull
Chroicocephalus cirrocephalus
Distinctive gull. Breeding adults have a gray hood, pale eyes, and a red bill and legs. The back is medium gray and the wings have extensively dark flight feathers. Loses the gray hood in the nonbreeding season which is replaced by a dark cheek spot, while juveniles have paler bills and variably brown mottled wings and back.

Rock Partridge
Alectoris graeca
This well-marked European endemic prefers rocky slopes and dry areas of hill and montane forest. Up to 3,000 m (10,000 ft), but can be found in lower-lying open flat areas with sparse grass and low bushes in some regions. Highly territorial and vocal, giving an irregular series of "chick chek pe-ti-chek chi-chek" notes, particularly in the early morning. Often runs away rather than flying. Throat is white, while similar looking Chukar has a creamy throat; virtually no overlap in range with other similar species.

Sulawesi Fantail
Rhipidura teysmanni
An active rufous-colored songbird with a long tail that is regularly cocked and fanned. Has a brown upperside, a rufous-washed wing, and a largely rufous tail with a bold darker terminal band. Head is brown with a conspicuous white throat and a rich rufous brow. Note the black chest patch and pale belly. Singles and pairs can be found at middle to upper levels of montane forest, often in mixed-species flocks. Confined to Sulawesi. Unmistakable: the only fantail on Sulawesi. Song is a sequence of high-pitched, rapidly descending notes, “WIT--wit-dee-dee-de-doo-doo.” Calls include a sharp, shrill “tzip” and “tchew.”
