Gray-headed Oliveback
Delacourella capistrata
A large, spectacular, distinctive olive-and-grayish waxbill with a white face and cheeks and a striking black bib that recurves under the cheeks as a jaw-stripe. Juvenile is duller and darker than adult. Resident in grassy moist savanna, thickets near water, and riverine woodland, where it feeds both in trees and on the ground. Calls include a high-pitched “tssssp”; song is a series of whistles slowing down and descending in pitch.

Cape Verde Storm-Petrel
Hydrobates jabejabe
Very similar to Band-rumped and Monteiro's Storm-Petrels, and closely related to those taxa. Breeds only on Cape Verde islands. There are no published field identification features to tell them apart. However it appears that its upperwing pattern is more contrasting and the rump patch is broader. Breeds in burrows and crevices on islands. Burrow calls are different from Band-rumped and Monteiro's by being extremely long, without pauses.
Green Thorntail
Discosura conversii
Tiny hummingbird with short straight bill. Male all shimmering green with distinctive, long, pointed tail feathers. Female has short tail and a distinctive white mustache. Both sexes show white band across rump. Most similar to coquettes but without orangey tones. Found in forested habitats and gardens; visits feeders.
Black Wood-Pigeon
Columba janthina
The largest pigeon in the region, with dark purplish plumage except for metallic green around the neck. Generally uncommon endemic of islands off Japan, and to a lesser extent South Korea and Taiwan. Occurs in mature broadleaf forests, where it forages on the ground or in canopy. Also favors pines, especially in the Ryukyu Islands. Rustles about loudly when feeding. Deep call and slow moaning song may recall the everyday Rock Pigeon.
