Olive-winged Bulbul

A small bird with a long blue tail that is held cocked. Breeding males are usually brilliant sapphire blue with bright white wing patches. Females and nonbreeding males are very plain pale gray, and the patch between the eye and bill (lores) is also pale (compared to Purple-backed Fairywren which has very dark reddish lores). This species is typically found in very open and arid country with sparse bushes, where it often perches on the very top of bushes. Its call is a very fast trill.

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.

Restricted to the Azores, Canary Islands, and Madeira. Slightly bigger than European Serin and yellow-green overall with a pale bill, and a dark forked tail. Has a streaky rump, but this can be hard to see. Males are greenish-yellow below while females are duller and grayer on the breast and neck. The song is very melodic and rich. Found in forests, plantations, gardens, and orchards, sometimes gathering in flocks. Introduced to the Midway Atoll, where coloration ranges from unstreaked bright yellow to almost white.
