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.

Pale-throated Pampa-Finch
Embernagra longicauda
Large finch with a long spiky tail. Mostly gray with olive-green wings and tail. Note the bicolored bill (dark above and yellow-orange below) and the broken white eye-ring. Inhabits higher elevations, in dry scrub, rocky areas, and grassy fields with scattered palms. Sings a high, thin “tsi, tsoweee,” repeated continually.
Buff-faced Scrubwren
Aethomyias perspicillatus
A very small, drab bird of montane forest understory. Pale brown underparts, dark brown upperparts, Gray from the crown to upper back widening to a half-collar. Distinct buff face forming a disk around the eye. Found in active groups or mixed flocks, where it gleans leaves for insects. Similar to Large Scrubwren but Buff-faced is often found higher in the trees, is smaller with a buff eye-ring and gray crown. Song, an up-and-down, whistled “poo-pii-poo-pii-poo-pii!” and call, a nasal “rek!”.
Ouvea Parakeet
Eunymphicus uvaeensis
Spectacular, relatively large mostly green parakeet with a black face, slight bit of red on the forehead, and thin but prominent “horns” consisting of a crest made up of a pair of black feathers. Typically found in remnant patches of high-quality forest, but visits more disturbed habitat nearby, especially where fruiting trees are present. Found only on Ouvea Island off New Caledonia. Note distinctive voice: relatively low-pitched, nasal trumpeting notes, notably lower-pitched than the voice of Coconut Lorikeet.
