Rufous Hornbill
Buceros hydrocorax
A large hornbill of lowland and foothill forest. Body dark, with rufous thighs, chest, and neck, a whitish tail, a red casque, a long red bill, and a black face bordered behind with yellow. Females have a smaller casque, a paler eye, and no eye-ring. Southern birds have a yellow-tipped bill. Similar to the Writhed Hornbill, but Rufous lacks the black tip to the tail and has a rufous rather than black or pale head. Voice includes loud, downslurred nasal honking notes.

Behavior
It is sometimes called "the clock of the mountains" because of its periodic noontime call. It has been recorded to have been preyed upon by the Philippine eagle.<p>As with other hornbills, females seal themselves within the nest cavity, where they lay the clutch, and remain with the growing young for most or all of the nesting period. In some species, the male helps with the sealing process from outside the nest cavity. The nestlings and the female are fed by the male through a narrow vertical slit in the sealed nest opening, at times joined by non-breeding helper males. Nesting time will last in average of 4–6 months. In this duration the male will provide food to his confine female and nestling. They maintain the year- pair bonds and will paired together until many years’ time and engage a courtship feeding.<p>Rufous Hornbills play a crucial role in maintaining the balance of their ecosystem. They are considered a keystone species due to their omnivorous feeding habits, which allow them to disperse seeds along the forest floor from the fruits they consume and control pest populations of insects they predate on.

Other Birds
Varzea Piculet
Picumnus varzeae
Tiny, dark brown woodpecker. Plumage varies; typically darker and more unmarked in the east and more barred toward the west, but usually looks scaled with white spots. Males have a red forehead. Found across a restricted distribution in seasonally flooded forests and on river islands.
Dotted Tanager
Ixothraupis varia
Small, beautiful tanager with bright uniform green plumage. Males have bluish wings and tail and scattered dots on breast. Note the dark lores. Females are all green and lack the dark lores. Found patchily in the canopy of humid forest and forest edges, typically in white sand areas or ridgetops, and often found with mixed-species flocks. Easily confused with juveniles of Yellow-bellied and Spotted Tanagers. The song is a very high, hissing “tsip... tsee-tseee-tsee-tsee-tsee”.
Little Rock-Thrush
Monticola rufocinereus
A small rock-thrush with blue-gray upperparts and hood and an orange belly. The tail has a black-and-orange “T” pattern that is conspicuous in flight. Males and females vary slightly: males are cleaner blue-gray above, while females are more brownish. Found locally in a variety of habitats with a mix of rocks, trees, and bushes. Sometimes also on and around human structures. Similar to redstarts, but easily distinguished by the clean gray hood and the lack of black on the face. Also similar to male Rufous-tailed Rock-Thrush, but smaller, lacking white on the back, and with a more extensive gray hood. The quiet song consists of musical phrases that can be short or quite long.
