Genovesa Cactus-Finch
Geospiza propinqua
This Galápagos finch is confined to the island of Genovesa. It has a fairly large bill that appears slightly elongated. The only other finch on Genovesa with a similarly-sized bill is Large Ground-Finch. Compared to that species, Genovesa Cactus-Finch has a smaller, less rounded bill that is noticeably longer than it is deep. Bill is pure black on breeding male, and marked with yellow or orange on female and non-breeding male. Male’s plumage is sooty-black; female is brown with paler underparts that are blotched with gray. Common in arid areas near the coast, and often seen feeding on prickly pear flowers.
分类信息
The large cactus finch is one of Darwin's finches, a group of closely related birds which evolved on the Galápagos Islands. The group is related to the Tiaris grassquits, which are found in South America and the Caribbean. An ancestral relative of those grassquits arrived on the Galápagos Islands some 2–3 million years ago, and the Española cactus finch is one of the species which evolved from that ancestor.<p>Some taxonomic authorities, including the International Ornithologists' Union, have split the species from the Española cactus finch. Others still consider them conspecific.

Napo Sabrewing
Campylopterus villaviscensio
Large, dark hummingbird found in cloud forest along the east slope of the Andes. Ranges from far southern Colombia south to northern Peru. Male has large blue patch on throat and breast, and a glittering green crown. Female has gray underparts; she is similar to Gray-breasted Sabrewing but has narrower white tail tips. Also note white spot behind eye. Infrequently encountered, though does visit feeders in some areas.
Hen Harrier
Circus cyaneus
Medium-sized harrier, flies with wings held in a V-shape, low over open fields and marshes, listening for rodents lurking below. Distinctive foraging behavior and conspicuous white patch on rump in all plumages. Five long primary ‘finger tips’ prominent in flight. Females and immatures are warm brown with streaky breasts. Adult male has plain mid-gray wings with black wingtips and paler belly.
Palm-nut Vulture
Gypohierax angolensis
Small, odd, distinctive vulture. Adults are boldly patterned black-and-white, with red bare facial skin. Juveniles are brown. Immature birds show a mixture of juvenile and adult traits. Distinctive shape in flight: broad, paddle-shaped wings and a short, wide tail. Found in a variety of habitats, including forest, woodland, and savanna--usually in the vicinity of palms. Somewhat similar to African Fish-Eagle, but easily separated by red facial skin and different pattern of black and white. Juveniles are similar to Hooded Vulture, but are smaller, with a thicker bill.
