分布与栖息地
It inhabits primary and secondary dipterocarp forest, mangrove swamps and forest edge up to 900 meters above sea level. It has also occasionally been recorded visiting farmland and cultivations. It requires large trees for nesting. While they can tolerate secondary forest, they have the highest population densities and health in primary (old-growth) forest<p>It is officially classified as vulnerable with the population estimated at 2,500 to 9,999 mature individuals remaining with its numbers have reduced by at least 20% in the last 10 years due to habitat destruction, hunting for food, and the live bird trade. It is threatened by habitat destruction through logging, conversion into agricultural land or urban development and mining.<p>Most visiting birdwatchers travel to St Paul's National Park, Palawan, to see this bird, but it is now uncommon. It acts as a bio-indicator due to its sensitivity to environmental changes.<p>The species is present in conservation areas - the entirety of Palawan has been designated a biosphere reserve but actual protection and enforcement against logging and hunting has been difficult. There are populations in several other protected areas such as Puerto Princesa Subterranean River National Park, El Nido Marine Reserve and others. It is listed in CITES as Appendix II.<p>Conservation actions proposed include surveys in remaining lowland forests throughout its range. Seek greater control of the cage-bird trade and assess its impacts. Research its ecological requirements and conduct nest protection schemes. Support the proposed extension of Puerto Princesa Subterranean River National Park and formally protect the forests at Iwahig Prison and Penal Farm. Carry out awareness campaigns regarding the protected status of the species. Allocate greater resources towards more effective control of hunting in Palawan forests and initiate conservation awareness campaigns amongst forest product collectors.

Eastern Parotia
Parotia helenae
A fairly large, short-tailed bird of mid-montane forest canopy. Male is mainly black with a bronzy-scaled chest and 6 antennalike feathers projecting from the back of the head. Note the blue eyes. The female is warm-brown above with barred underparts and a black head. The male has an elaborate dance at a terrestrial display court. Females are similar to female lophorinas, but are larger and lack a pale eyebrow stripe. The vocalizations are poorly known, but likely include various rasps and parrotlike squawks.
White-billed Buffalo-Weaver
Bubalornis albirostris
A big, bulky, long-tailed black weaver. The bill is white in males and black in females. There is a white patch on the front edge of the shoulder, and also a pale patch in the wing that can be conspicuous in flight. Immatures are dark brown with heavy streaking below. Found in dry savanna and woodland, often in flocks. Builds huge communal stick nests. Similar to Red-billed Buffalo-Weaver, but never shows a red bill. The common call is a harsh “sjet” that is often given repeatedly by a whole group in chorus.
Red-chested Buttonquail
Turnix pyrrhothorax
Small, dark, secretive buttonquail with pale eye, found in dense grassland habitats, where most commonly observed exploding from cover and flying rapidly away. In flight, note the fairly uniformly dark upperparts, with less contrast between flight feathers and coverts than in most other buttonquail. Adult female has rich rusty-orange chest; male paler, with white chin. Call is a repeated "oom-oom-oom-oom," with end of each note ascending in pitch.
