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.
Taxonomy
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.

Range and habitat
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.

Other Birds
Yellow-throated Tanager
Iridosornis analis
A well-named and colorful tanager found in cloud forest along the east slope of the Andes. Blazing yellow throat stands out sharply against its otherwise mostly bluish plumage. Also note black face and rusty vent. No range overlap with the similar Purplish-mantled Tanager. Usually stays low in the forest, though occasionally ventures higher at a fruiting tree. Not strongly associated with mixed-species flocks.
Yungas Warbler
Basileuterus punctipectus
This attractive warbler is nearly endemic to the Bolivian Andes, barely reaching over the border into Peru. Note the ornate head pattern and olive (not yellow) plumage. Most similar to Riverbank Warbler and the white bellied form of Golden-crowned Warbler, but has a dark loop below the eye and is found at higher elevations. Usually seen in pairs at lower to middle levels of cloud forest. Song is a rising series of piping notes followed by a chatter. Formerly considered a subspecies group of Three-striped Warbler.
Chinese Egret
Egretta eulophotes
Medium-sized white egret. Breeding adult has bright blue loral skin, a pinkish-orange bill, and long frilly plumes on the head, neck, and back. Nonbreeding adult lack plumes and has dull greenish legs and bill. Nonbreeding birds can be confused with Little Egret, but note Chinese Egret's thicker bill, proportionally stouter legs, orangish base to the bill, and dark lores with a shallow crook between eyes and bill. Light morph of Pacific Reef-Heron may also be similar, but average much thicker-billed and thicker-legged than Chinese. Moves between craggy islands and coastlines when breeding; winters in mangroves, estuaries, and mudflats.
