Vigors's Sunbird

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.

A medium-sized bird of mid-montane forest. Yellow belly, olive back and white throat. Male has a black head and border to the throat. Female has a brown head and diffuse olive chest band. The male is similar to several other golden whistlers but lacks the yellow patch behind the head. Female is similar to Regent, Lorentz’s and Vogelkop Whistler’s but has white throat and brown head. Voice, a series of typical whistlerlike “chew!” or “whip!” notes that get louder and end with an explosive quality.

Small, stocky flycatcher with broad, flat bill. Occupies canopy and midstory of forest edges, gardens, and tall second growth in humid lowlands. Has gray crown, pale yellow underparts, and yellow edgings to wing feathers (but not wingbars). Very similar to a few other species of flycatchers, particularly Yellow-margined and Yellow-olive Flycatchers; best distinguishing features include its pale eye, lack of a yellow patch at the base of the primaries, and voice. Call is a loud, quickly rising whistle: “tuee?”, higher and cleaner than similar calls from species like Brownish Twistwing and Blue-backed Manakin, but not as high as the “twee-twee” of Purple-throated Euphonia.
