Madagascar Buzzard
Buteo brachypterus
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.

分布与栖息地
Endemic to Madagascar where it is common, except for the deforested central plateau where it is less common, there is some indication that its population is increasing as the forest is fragmented.<p>The Madagascar buzzard is adaptable as to its habitat and is found in a wide variety of habitats including forest, open woodland and regenerating, secondary forest. It can also be found on rocky hillsides up to 2300 metres above sea level. Although it is so adaptable it is still less common on the deforested central plateau.

Indigo Bunting
Passerina cyanea
Breeding males are entirely blue with a slightly darker head. Females are plain brown with a whitish throat, bluish tail, and faint streaks on the underparts. Breeds in shrubby areas at the edge of forests and fields. Males often sing from a high exposed perch. Winters mainly in Middle America and the Caribbean, where it frequently gathers in flocks in weedy fields. Females can be very difficult to distinguish from Lazuli Bunting, although their range doesn't overlap much. Indigo usually shows more streaking on the underparts; also note fainter wingbars, duller breast, and more contrasting whitish throat.
Gray Gull
Leucophaeus modestus
Distinctive and often noisy and conspicuous. The only dark gull in its range in the Humboldt Current. Common over inshore waters and along the coast on sandy beaches, at river mouths, and on adjacent rocky coasts, but breeds inland in remote areas of the Atacama Desert. Breeding adult has a white head while immatures are brown overall; all ages have slender black bill and dark legs. Immatures look like adults in 3 years.
Olive-shouldered Parrot
Aprosmictus jonquillaceus
A large, long-tailed green parrot with an orange bill and a wing patch, red in males and yellow in females, that is visible both perched and in flight. Juvenile is like female, but lacks wing patch. Singles or small flocks can be found in a variety of wooded areas, like forests and plantations, in lowlands and mountains. Limited to a few islands in the Lesser Sundas. Distinguished from Olive-headed and Marigold Lorikeets by its larger size, its broad square tail, and its lack of a dark hood. Gives raucous, shrill screeches, high-pitched tinkling, and lower-pitched “kraak-kraaak” calls.
