A fairly small owl of lowland forest on Mindanao. Dark brown on the head and upperparts with speckles on the wing, a reddish-brown chest, a white belly with thick reddish-brown streaking, and yellowish eyes.

The males and females look much alike.<p>Among the species complex, this owl is differentiated by its call which sounds closer to a dove than the typical screeching of the boobooks. It also has smaller size and mottled dark and light rufous brown streaking on its breast and whitish belly.<p>It, along with the even smaller Luzon boobook, are among the smallest in the Philippine hawk-owl species complex, at 18 cm. This is smaller than the Mindoro boobook and Sulu boobook which are 20 cm tall. These species are dwarfed by the much larger Camiguin boobook, Romblon boobook and Cebu boobook at 25 cm tall.

分布与栖息地
Its habitat is in tropical moist lowland primary forest.<p>The IUCN Red List classifies this bird as near-threatened with population believed to be declining. 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 and plantations and urbanization. Its entire range has suffered extensive lowland deforestation. In 1988, forest cover had been reduced to an estimated 29% on Mindanao, most of it above 1,000 m<p>There are no species specific conservation programs going on at the moment but conservation actions proposed include more species surveys to better understand habitat and population. initiate education and awareness campaigns to raise the species's profile and instill pride in locals. Lobby for protection of remaining forest.

White-headed Duck
Oxyura leucocephala
Remarkable odd-looking diving duck with a long tail, often held cocked. Males have a striking white face and black crown that contrasts with their large blue bill and chestnut body. Female and juveniles have a darker brown bill, more extensive dark crown and pale cheek stripe, similar to Ruddy Ducks. Silent and rarely flies. Rare and local. Usually found in shallow, open water with dense aquatic plants.
Little Spotted Kiwi
Apteryx owenii
New Zealand’s smallest kiwi species. Light grayish brown with white horizontal banding or “spotting” along the length of the body. Restricted to offshore predator-free island sanctuaries and to the mainland Zealandia sanctuary in Wellington. More often heard than seen, including loud sniffling as it forages for invertebrates. Male produces a series of burry, rising high-pitched whistles. Female has a lower ascending burry whistle. Both sexes repeat their call many times, often duetting. Could be confused with Weka by voice and shape; look for the kiwi’s much longer bill and lack of tail, and listen for its multisyllabic call.
Brown Prinia
Prinia polychroa
A dull and poorly marked prinia with a strong bill and a long, graduated tail. Light brown above with faint dark streaking. Pale below, sometimes with some dark smudging along the sides of the breast. Found at low and moderate elevations in open dry forest, shrubby areas, and forest or agricultural edges. Can be retiring and difficult to see in dense vegetation. Sings two different song types: a dry rolling trill and a repeated two-syllabled “tulip.” Separated from other prinias by its overall plainness and lack of contrasting head markings.
