Sulu Boobook
Ninox reyi
A fairly small owl of forest on the Sulu Islands. Uniformly barred, with brown upperparts and head, orange-brown underparts, white speckling on the wing, a broken pale bar behind the shoulder, a pale belly, long whiskers around the face, and yellow eyes. Note the white throat patch. Probably the only owl in its range except for Mantanani Scops-Owl, but Sulu Boobook is rufous rather than gray and lacks the black line around the face. Voice includes strange clucking notes starting with a rapid series ending in three slower notes: “kukukukukuku klok-klok-klok.”

EBird describes the bird as "A fairly small owl of forest on the Sulu Islands.

Voice includes strange clucking notes starting with a rapid series ending in three slower notes: 'kukukukukuku klok-klok-klok'."<p>Among the species complex, this owl is unique with its call of a series of clucks rather than the typical screeching of the other Philippine hawk-owls in the species complex. It is distinguished by the heavy barring on its head and belly, white throat-patch and facial disk.<p>It is medium-sized at 20 cm tall, along with the Mindoro boobook within Philippine hawk-owl species complex. This is in between the larger Camiguin boobook, Romblon boobook and Cebu boobook at 25 cm and the smaller Luzon boobook and Mindanao boobook, which are 15 to 18 cm tall.

分布与栖息地
Its habitat is in tropical moist lowland primary and secondary forests up to 700 meters above sea level. It is also occasionally seen on forest edge, clearings and plantations. On Tawi-Tawi, the species is also found in mature mangroves and large trees in the vicinity of villages <p>The IUCN Red List classifies this bird as vulnerable with population estimates of 1,000 to 2,499 mature individuals. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of legal and illegal logging, mining, conversion into farmlands or palm oil plantations and urbanization. Due to the rapid loss of habitat in the Sulu Archipelago, many of the birds endemic to the region like the Sulu hornbill, Tawitawi brown dove, blue-winged racket-tail and the Sulu pygmy woodpecker are threatened with extinction.<p>There is no species-specific conservation program at present.

其他鸟类
Scaly-breasted Lorikeet
Trichoglossus chlorolepidotus
Medium-sized green lorikeet with yellow ‘scales’ on the breast. Note bright red bill and orange-red underwings. Much shorter-tailed than Rainbow Lorikeet. Typically occurs in woodland habitats in eastern Australia, but is also present in parks and gardens. Call is similar to Rainbow Lorikeet, but smoother and less squawky.
Ring-necked Duck
Aythya collaris
A relatively small diving duck with a tall peaked crown. Males are handsome with glossy black head and back, clean gray sides, and a brighter white spur on the side. Females are grayish-brown, often with a paler patch at the base of the bill and a white eyering. Both sexes have a white band near the tip of gray bill. Also note gray, not white, wingstripe in flight. Usually favors small bodies of water, such as beaver ponds and cattail marshes, but also occurs on larger lakes, rivers, and bays. Can be found in mixed flocks with other diving ducks, although usually in smaller numbers than scaup. Compare with both species of scaup and Redhead (especially females).
Antipodes Parakeet
Cyanoramphus unicolor
Entirely green parakeet endemic to the subantarctic Antipodes Islands. The largest of New Zealand’s native parakeets. Males are larger than females. Common throughout their habitat and range, walking and climbing through vegetation when foraging. Will scavenge bird carcasses. An inquisitive bird, often approaching human visitors. Call is a distinctive deep “kok-kok-kok-kok” chatter. Shares its range with Reischek’s parakeet, but distinguishable by much larger size and lack of a red crown.
