保护状况
This woodpecker is critically endangered. It has a single tiny, declining population which is threatened by habitat loss of mature forest due to logging, dam construction, agriculture, military and golf course developments. A major problem now is that one of their main habitats is being destroyed. The current population is estimated at less than 600. This species is suspected to be declining at a rate of 10-19% over ten years, as a result of ongoing clearance of old-growth forests.<p>This woodpecker is legally protected in Japan. It occurs in Yonaha-dake Prefecture Protection Area and small protected areas on Mount Ibu and Mount Nishime and conservation organisations have purchased sites where it occurs, but it is mainly found in the Okinawa Prefecture. In 1996, Yambaru was designated as a national park.<p>The habitat of the Okinawa woodpecker is threatened by the construction of six new American helipads located about 9.5 km Southwest of the Yanbaru forest of Takae. The lives of the birds themselves are also put at risk by the flights of V-22 Ospreys over the island.

Blue-naped Pitta
Hydrornis nipalensis
A rotund, earthen-toned ground-dweller, usually hidden deep in the undergrowth of dense forests, often in damp areas near rivers and streams. Very shy, rarely venturing out into the open, though can sometimes be seen on the sides of trails in the early morning. Male has a bright sky-blue crown and nape, tea-green wings, and an ochre-brown belly. Females have a brownish head and are a browner-toned shade of green on the wings. Song is far-carrying and simple: a loud, piercing “pee-ya!”
White-thighed Hornbill
Bycanistes albotibialis
A large canopy hornbill with a distinct white-tipped tail, a broad white outerwing with white patches within the black forewing, a white belly and vent, and a pale bill. Often seen in the canopy and subcanopy of lowland forest feeding on fruit. Call is a harsh series of caws, “hyr hyr hyr,” with occasional longer wails. Most likely to be confused with Black-and-white-casqued Hornbill, but White-thighed Hornbill has white on the vent and rump and on the tail tip, giving its tail a black-banded appearance, and its bill is pale.
Cream-colored Woodpecker
Celeus flavus
Distinctive yellow woodpecker of lowland Amazonia. Bright creamy yellow overall with short creamy crest, brown wings and tail, and yellow bill; male has red moustache Usually found in seasonally flooded and swampy forested areas, but can be found outside those habitats occasionally in other forested areas. Listen for a loud, descending series of whistles: “PEE-pee-pee-peer.”
