Hairy-breasted Barbet
Tricholaema hirsuta
A big dark barbet of humid forest of low and middle elevations. The back is black with yellow spotting and the underparts are yellow with black striping and spotting. The head pattern varies geographically. The throat can be striped or solid black, and the face can be speckled (central Africa) or black with a white eyebrow and moustache mark (northern and western parts of the range). Somewhat similar to Yellow-spotted Barbet, but larger overall with a bigger bill and a dark cap. Usually detected by voice: a long, slow series of low, hollow hoots. Occasionally also gives a much faster tooting series.

行为
The hairy-breasted barbet usually feeds singly or in a pair. Its diet consists of fruits, including drupes and berries, along with insects, such as beetles and caterpillars. It has been observed to remove wings and legs from insects by bashing them on branches.<p>It sometimes joins mixed-species foraging flocks.<p>Each pair defends a territory, and both the male and female sing. The song is repeated oork or oop notes. While a bird sings, it spreads out some of its feathers, puffs its throat and rotates its head from side to side. In flight displays, it swoops downwards and it also glides without moving its wings. Its breeding is not well known. It has been found in cavities in trees, but it is not known if it nests in these cavities. Breeding activity, including in females with large ovaries and juvenile birds, has been observed in different parts of the year in different regions.

Turquoise Flycatcher
Eumyias panayensis
A striking, largely bright turquoise-blue flycatcher with a white belly and prominent black mark between bill and eye. Juvenile is brown and extensively spotted, with blue wings and tail. Inhabits understory and upper levels of foothill and montane forest, where singles or pairs frequently join mixed-species flocks. Unmistakable within limited range in Indonesia and the Philippines. Song is a short, unchanging jumbled warble with no obvious introductory or ending notes, giving the impression that it starts and ends right in the middle of the song.
Red-capped Flowerpecker
Dicaeum geelvinkianum
Tiny bird, black above, pale below, with fiery bright red cap, red chest patch, and red rump. Plain juvenile has orange bill but otherwise unmarked; lacks the reddish undertail of juvenile Mistletoebird. Found in mangroves and forest on New Guinea and islands in the northern Torres Strait. Calls similar to Mistletoebird, a high-pitched short "seeep" and buzzing sounds.
Rufous-bellied Bush-Tyrant
Myiotheretes fuscorufus
Subtly patterned reddish-brown flycatcher of high-elevation montane forests. Perches upright, often on the tops of snags or bushes around forest edges and clearings. Grayish brown above, warm tawny reddish below, with reddish wingbars and a weak black eye-line. Listen for a series of short bouncing notes followed by a punctuated ending note: “pip-pip-pip, pi-PEW.”
