Luzon Boobook
Ninox philippensis
A fairly small owl of lowland and foothill forest and edge. Brown on the head and upperparts with a slight speckled effect, and whitish below with thick reddish-brown streaks. Note bright yellow eyes and long whiskers around the face. Similar to Chocolate Boobook, but Luzon is much smaller and lacks any white on the chest. Voice includes a single short, descending “boo!” repeated at intervals, and a short phrase “boo! wup-wup boo!”
识别特征
The Luzon boobook is one of the smallest of the owls in the Philippine hawk-owl complex. It has white eyebrow-like streaks above the eyes and the beak and a white moustache forming an x-shape on the head. It does not have tufts of feathers on its head resembling ears. The upper parts of all subspecies are brown and the wings are mottled with oval-shaped white spots. The tail is dark brown with narrow white stripes. The sides of the head are brown, the chin is a whitish colour, while the rest of the underparts are pale white with wide brown streaks which are more prominent on the breast. The underside of the tail is white. The chequered subspecies have these reticulated patterns on the underparts, on the head, the upper parts of the back and the wings. The feet are partially covered with feathers and are pale yellow. The beak is olive.

行为
The Luzon boobook can be found in forest areas up to an altitude of 1,800 m (5,906 ft) above sea level, although they mostly reside in areas below 1,000 m (3,281 ft). Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. The breeding season for this species starts around February utilizing hollows in trees as nesting sites. It feeds on insects and small rodents.
保护状况
They are locally common within that range and the population size is believed to be stable. The owls face no particular threats, and as a result, the IUCN has listed the group as being of "least concern" as it is also tolerant of secondary forest and clearings.

Cape Spurfowl
Pternistis capensis
A large, mostly dark brown francolin with pale feather-edging that forms a fine scaly pattern on the body. It also has dull red legs and a mostly reddish bill with a dark top and yellow base. The pale eyebrow and throat are emphasized on a dark face. The juvenile is duller. The loud, territorial crowing call (“kak-kaak, kak-keek, kak-keek”) is given from a low perch; it increases in pitch but decreases in volume. Bold and confiding, it is widespread and common in its range; found in fynbos, semi-arid zones, and coastal scrub. Gray-winged Francolin differs by having yellow legs, a rufous-streaked chest, and a gray-and-brown necklacing pattern.
Golden-crested Myna
Ampeliceps coronatus
Unmistakable glossy black bird with a dash of bright yellow on the head and wings. Male has more extensive yellow on the head than the female. Inhabits lowland to foothill evergreen forests where it forages in pairs or small flocks up in the canopy. Look out for their flashing yellow wing patches as they move between trees. Like other mynas and starlings, gives a variety of gurgles, croaks, and high-pitched fluid notes.
Blue-gray Noddy
Anous ceruleus
A very small, pale gray tern with large dark eyes. Smaller and paler gray than Brown and Black Noddies with slightly more of a forked tail. Nests on rocky sea cliffs on tropical islands, typically foraging close to shore, fluttering close to the water and plucking food from the surface in small flocks. Voice is a distinctive nasal “kearr.”
