Prioniturus montanus
A medium-sized parrot of montane forest on Luzon. The two central tail feathers have extended shafts ending in a racket shape. Overall green in color, darker on the back and paler below. Male has a blue face and a red crown. The similar Green Racquet-tail may overlap geographically, but Luzon is usually found at higher elevations and has a darker back. Voice includes various grating calls and shrill squeals.

分布与栖息地
It inhabits tropic moist montane forest at 700–2,900 meters above sea level. Has been to known to visit cultivated areas.<p>IUCN has assessed this bird as near threatened with its population being estimated as 1,500 to 7,000 mature individuals. . Forest loss is a threat but it is not thought to have as significant impact within this species's alititudinal range as compared to lowland forest. Its lowland counterpart the Green racket-tail is considered much more threatened being listed as endangered with many local extinctions. Many parrots in the region are affected by trapping for trade, but its impacts upon this species are not known.<p>It is recommended to gather data on the impacts of international and national trade. Undergo surveys to have a better population estimate. Calculate rates of forest loss within its altitudinal and geographic range using satellite imagery and remote sensing techniques.

Semipalmated Sandpiper
Calidris pusilla
Small, grayish-brown sandpiper. Typically shows relatively short, blunt-tipped bill, but this varies across the breeding range: western populations are shortest-billed, eastern populations are longest, and females have longer bills than males! Also note blackish legs, although they can appear dull gray or greenish. In breeding plumage, fairly pale grayish brown, sometimes with brighter rusty cap and cheek. Nonbreeding is plain gray above and white below. Juveniles have attractive scaly pattern on upperparts, and variable coloration: usually grayish with some buffy areas, occasionally brighter rufous. Most similar to Western and Least Sandpipers. Western averages slightly larger and longer-billed, with brighter rufous on breeding adults and juveniles; nonbreeding birds paler but extremely similar to Semipalmated. Least Sandpiper is darker and browner. Breeds on high Arctic tundra. Migrates to South America for the winter; very rarely lingers in the U.S. past November, unlike Western Sandpiper. Usually found in flocks, sometimes in very large numbers. Prefers open mudflats, but also found in marshes and beaches.
Mao
Gymnomyza samoensis
A large, entirely dark honeyeater. Plumage becomes paler from the shoulders back, turning blackish to yellowish-olive. Note the caramel-colored moustache stripe below the eye. Dependent on native primary forest in foothills and montane areas. Voice includes a sequence of rising nasal piping notes, vocal and loud.
Red-faced Parrot
Hapalopsittaca pyrrhops
Rare and threatened parrot found only in high Andean forest in southern Ecuador and adjacent parts of northern Peru. Small compared to most other parrots. Red face is bordered with patches of blue and yellow. Wings are green and blue with red on the shoulder. Usually encountered in pairs or small flocks that fly over the forest and then disappear into the canopy, where they can be very hard to pick out as they forage for fruit behind the foliage.
