Black-hooded Coucal
Centropus steerii
A large, long-tailed bird of lowland primary forest on Mindoro with a brown back and belly, dark wings with brown-edged feathers, a dark tail with a bluish iridescence, and a black hood with some light streaking on the back of the neck. Note the strong curved bill. Similar to Philippine Coucal, but has a brown rather than black belly and is restricted to primary forest rather than more open habitats. Song is a descending series of very deep hoots.

分布与栖息地
Its natural habitat is tropical moist lowland forest. It is threatened by habitat loss with Mindoro having a great loss of forest in recent decades. By 1988, extensive deforestation on Mindoro had reduced forest cover to a mere 120 km2 (46 sq mi), of which only a small proportion is below this species's upper altitudinal limit. The lowland forest that does remain is highly fragmented and it is believed that at the current rate of deforestation all forest may disappear by 2020–2030. Slash-and-burn cultivation, occasional selective logging and rattan collection threaten the forest fragments that still support the species. Dynamite blasting for marble is an additional threat to forest at Puerto Galera. The species's genetic viability may be at risk given the small size and fragmented nature of remaining populations. As a consequence, it is now classified as critically endangered by the IUCN with an estimated population of just 50 - 249 mature individuals.<p>In order to combat extinction, local education programs have been initiated, surveys have been executed, and ecotourism has been promoted in order to encourage locals to take to more sustainable occupations. The Zoological Society of London has described the bird as an EDGE species, listed as the top 21 distinct-endangered bird species in the world. Conservation actions proposed by the IUCN include more surveys to better understand population, to better protect the remaining lowland forests and to raise awareness on this species.

Yellow-capped Pygmy-Parrot
Micropsitta keiensis
A tiny parrot of lowland and foothill forest canopy in the south and west of New Guinea. Mostly green with yellow under the tail and a yellowish crown. NW birds have a red streak on the belly. Crawls actively on trunks, even upside down, like a nuthatch. May overlap with Red-breasted and Buff-faced but Yellow-capped lacks the blue crown and buff face. Call, a shrill, descending screech “kiiiiiii!”.
Gray-backed Cisticola
Cisticola subruficapilla
Medium-sized, streak-backed cisticola of uplands. Varies geographically: gray-backed and streak-breasted in the south, and rufous-backed and plain-breasted in the north. Found in fynbos and karoo habitats, usually in areas with a mix of rocks, shrubs, and grass. Generally inconspicuous; seen singly or in pairs. Song is a short, explosive, accelerating trill. Calls include a rising, two-part “chu-cheee”. Very similar to Wailing Cisticola, but has a different voice, a smaller bill, less buffy underparts, and doesn’t show rufous in the wing.
Lazuli Kingfisher
Todiramphus lazuli
A stunning blue-and-white kingfisher with entirely blue upperparts in both sexes. Female has white throat and pale blue breast and belly, but male shows more white, with pale blue confined to belly. Juvenile resembles dull male, with buff throat, spot near bill, and speckled breast and collar. Found singly and in pairs in lowland wooded areas, including cultivated areas and mangroves. Pale blue underside is unique among kingfishers in its limited south Moluccan range. Rowdy vocalizations include repetitive “ker-chick” series and “ki-ki-ki-ki…” calls.
