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. 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.

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.

White-throated Redstart
Phoenicurus schisticeps
Well-named; both the male and female have a white throat, as well as a long white wing stripe, a flashing orange rump, and a dark tail. The male has a dark gray hood, a black face, and a deep orange belly. The female is less brightly colored, but no other female redstart in range has her white throat and long wing stripe. Breeds at high altitude, in stunted bushes and conifers, and winters in at middle altitudes in open scrubby areas.
Black-crowned Tityra
Tityra inquisitor
Handsome, mostly silvery gray bird of tropical lowland forest and adjacent semi-open areas with taller trees. Usually found at mid-upper levels of fruiting trees, sometimes in small groups that mix readily with the commoner Masked Tityra. Black-crowned is told from slightly larger Masked by its solidly black bill. Male is more silvery overall, with a black cap; female had brown face and smaller black cap. Tityras nest in tree cavities, that they sometimes steal from woodpeckers.
Desert Owl
Strix hadorami
A shy, medium-sized owl of desert canyons. Sandy-brown overall with pale underparts and yellow eyes. Face and underparts are lightly marked, while the wing feathers and tail are boldly barred. Breeds in crevices, caves, and cliffs in desert canyons. Male song is a soft hoot, "Hu! Hu-hu hu-hu."
