EBird describes the bird as "A fairly large bird of lowland and foothill forest on Mindoro. Small for a hornbill. Bill fairly short with black bands. Has black wings, a pale buffy tail with black tip, pale underparts and head with a black cheek, and bare skin around the face and chin. Male has pinkish facial skin, while female’s is blue. Unmistakable. The only hornbill on Mindoro. Voice is a short nasal bark, “wak!”."<p>It is unique among the tarictic hornbills (Visayan hornbill, Luzon hornbill, Samar hornbill and Mindanao hornbill), which the others show a great deal of sexual dimorphism in which males have white heads and breasts while females are almost uniformly black. In the case of the Mindoro Hornbill, both males and females have white heads and bellies with the only physical features to distinguish sexes being the facial skin in which the females' are blue with the male's being pink in color.<p>Like all hornbills, they are cavity nesters and rely on large dipterocarp trees for breeding.<p>They are primarily frugivorous eating figs and berries but they are also known to eat insects, lizards and other small animals.

分布与栖息地
It is found mostly in tropical moist primary lowland forest up to 1,000. They are also seen in secondary forest and forest edge but they need the large trees to support their nesting habits.<p>The IUCN Red List classifies this bird as an endangered species with population estimates of 250 to 999 mature individuals which is the lowest estimate among all five tarictic species. 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, of which only a small proportion is below this species's upper altitudinal limit. The lowland forest that does remain is highly fragmented and is still under threat. Kaingin or 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. Hunting and poaching are also considered as significant threats.<p>It occurs in a few protected areas including Mt. Iglit-Baco National Park, where it shares habitat with the iconic Tamaraw and in Mt. Siburan in Sablayan which has been declared an Important Bird Area.<p>Conservation actions proposed include more surveys in areas where they have been reported to better understand the population, create formal protection in other sites where they are found in Malpalon, Puerto Galera and Manamlay Lake.

Orange-eyed Flatbill
Tolmomyias traylori
Rare flycatcher found in seasonally flooded swamp forest in lowlands east of the Andes. Pale eye, wide bill, buffy throat and breast, gray crown, and lack of facial markings help separate it from similar species such as Gray-crowned Flycatcher. It is typically seen quite high in the trees, but usually not in the forest canopy. Song is a series of emphatic, raspy squeaks.
Red-eyed Vireo
Vireo olivaceus
Plain olive-green above and whitish below with no wingbars. Red eye of adults is not always easy to see; immatures have brown eyes. Dark stripe through and above eye. Larger and thicker-billed than warblers. Breeds in mature deciduous forest. Often sings nearly nonstop throughout the day; listen for repetitive musical phrases coming from the treetops. Often with flocks of chickadees and warblers during migration. Winters in South America, where it could be confused with the very similar Chivi Vireo, from which it is best distinguished by voice.
Northern Gannet
Morus bassanus
Large seabird of the Atlantic with long, pointed bill, wings, and tail. Adults bright white with cream-colored head and black wingtips. Takes several years to reach adult plumage; juveniles are all sooty-brown and slowly acquire more white as they mature. Nests in enormous colonies on cliffs in the North Atlantic. Spends most of its life at sea, although often fairly close to land, so they are often visible from shore or on whale watching boats. Dives torpedolike into the ocean for fish. Gathers in large feeding flocks, but sometimes solitary.
