Crimson-breasted Flowerpecker

Typical brown buzzard that is endemic to Madagascar. Found throughout the island in many different habitats, though absent from pure grassland. Voice is a series of increasingly strident wails, often given in flight. Distinguished in flight from Madagascar Cuckoo-Hawk by larger size, less paddle-shaped wings, and the pale panels toward the tips of the wings. When perched, look for a paler chest and heavily marked belly, whereas Madagascar Cuckoo-Hawk shows the opposite. Separated from immature Madagascar Harrier-Hawk by dark head and lack of pale fringes on the wing. 

Big, bright grosbeak of foothills and highlands; also lowlands locally in west Mexico. Found in tropical forest and edges, brushy woodlands, and shade-coffee plantations. Usually seen singly, occasionally in small groups, feeding quietly at all levels in fruiting trees. Note the very stout bill and white wing markings. Male is unmistakable: brilliant yellow overall in most of Mexico, but rich golden yellow in Chiapas and Guatemala. Female similar to female Flame-colored Tanager but bigger, with massive bill and white (not yellow) vent.

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.
