Streak-breasted Bulbul
Hypsipetes siquijorensis
A medium-sized bird of foothill forest and edge as well as more open wooded areas. Fairly large for a bulbul. Dark brown above with a pale belly and a warm brown chest and throat with pale streaking. Note brown cheek and black crown that can be raised into a spiky crest. Similar to Philippine Bulbul, but larger, with a longer bill, a black crown, and a paler throat and chest. Voice consists of rather unpleasant grating chatters and harsh downslurred squeals.

EBird describes the bird as "A medium-sized bird of foothill forest and edge as well as more open wooded areas. Fairly large for a bulbul. Dark brown above with a pale belly and a warm brown chest and throat with pale streaking. Note brown cheek and black crown that can be raised into a spiky crest. Similar to Philippine Bulbul, but larger, with a longer bill, a black crown, and a paler throat and chest. Voice consists of rather unpleasant grating chatters and harsh downslurred squeals." However, this description mostly refers to the siquijorensis sub-species (potentially a split). The other two sub-species have much lighter colored appearances and no spiky crown. <p>The streak-breasted bulbul was originally described in the genus Iole and later placed in the genus Ixos before being re-classified to the genus Hypsipetes in 2010. Alternate names for the streak-breasted bulbul include the mottle-breasted bulbul and slaty-crowned bulbul.<p>Three subspecies are currently recognized: It has been proposed that each should be elevated to the full species level with each having different calls and considerable differences in appearances.

分布与栖息地
It is found in tropical lowland moist primary and secondary forest. It is able to tolerate degraded habitat provided there is nearby forest but occurs in lower densities in these areas.<p>IUCN has assessed this bird as endangered with population estimates being 2,500 to 9,999 mature individuals and continuing to decrease. Although it can tolerate less than ideal forest, this species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range. Siquijor, Cebu and Tablas Island are some of the most deforested islands with just 8 km2 of forest remaining on Siquijor and 15km2 on Cebu. It appears to face interspecies competition from the Yellow-vented bulbul and the Philippine bulbul.<p>Conservation actions proposed include: the promotion of improved management of the existing reserves to prevent further habitat deterioration on Siquijor, Cebu and Romblon; the designation of further protected areas as appropriate, particularly on Tablas Island; the promotion of forest restoration and regeneration on Tablas Island; and on Cebu, investigation into the potential for targeted conservation, including captive breeding, of the subspecies monticola.

Spotted Tody-Flycatcher
Todirostrum maculatum
Tiny, subtly colorful flycatcher of riparian and secondary growth. Large-headed with a flat boat-shaped bill. Yellow with a gray head and fine black streaking all over. Song an even-paced series of high chip notes, usually transitioning into doubled notes, “peet, peet, peet-it, peet-it, peet-it, …”.
Rufous Piha
Lipaugus unirufus
Uncommon in humid evergreen forest of tropical lowlands, where lives mainly at middle to upper levels in forest canopy. Presence often revealed by loud whistled “PEE-HAH” calls, which can be given in response to loud noises such as a sharp handclap. Often perches still and rather upright for long periods, sallying out occasionally for fruit and small invertebrates. Plumage bright rusty overall, with paler eyering and slightly bushy face. Rufous Mourner looks very similar but smaller and sleeker.
Yellow-spectacled Heleia
Heleia wallacei
A small green songbird with a bright yellow head and a distinctive orange forehead smudge. Gray belly separates yellow throat and yellow base to undertail. Adults dark-eyed, juveniles pale-eyed. Pairs and groups inhabit dry, open areas in the lowlands and lower hills, such as savanna, scrub, forest patches, and thickets, avoiding dense forests. Restricted to the Lesser Sundas. Separated from Lemon-bellied, Ashy-bellied, and Warbling White-eyes by lack of a white eye-ring and presence of an orange forehead patch. Song is a descending stuttering warble. Also gives jarring churrs and twittering notes.
