Variable Limestone Babbler
Gypsophila crispifrons
A large, chunky, scraggly-looking babbler found in limestone hills covered with forest. Gray and brown overall with heavy streaking on the head, back, and throat. An odd white morph shows a variable amount and distribution of bright white on the head and breast. Forages close to the ground, often in and around rocky cracks and crevices. Song is a loud, ringing, rather hoarse-sounding sequence of whistled notes including some repeated phrases, sometimes given as a duet by a pair. Also gives harsh “grrr” calls. Similar to Streaked Wren-Babbler, but larger and longer-tailed, lacking white spots on the shoulder.

Black Manakin
Xenopipo atronitens
Small bird of dry scrub enclaves in rainforest regions. All-black male is distinctive; compared to other manakins, note longish tail and blue bill in both sexes. Locally common in low-stature forests and savanna scrub woodland, always in areas with extremely weathered, sandy soil. Eats fruit. Groups of males give vocal displays from dispersed perches, often well inside vegetation. Male resembles Amazonian Black-Tyrant, but has shorter bill and is unlikely to occur in the same habitat. Most common call is an unusual, squeaky chuckle; useful when searching for this bird in dense scrub.

Baird's Trogon
Trogon bairdii
Unique trogon with dark purplish head and breast, turquoise back, white undertail, and pale blue bill and eyering. No white band between chest and belly. Female mostly gray with red belly, perhaps most similar to Slaty-tailed Trogon but note pale blue eyering, gray bill, and thin white bars on undertail. Limited range. Look for a bird sitting upright and still at middle levels in the forest, slowly turning head searching for prey. Usually single or in pairs. Song is a fairly fast, accelerating series of cluck notes.

Javan Heleia
Heleia javanica
Small warbler-like bird with a gray head, yellowish-green body, and varying amounts of white around the eye; lacks the well-defined white “spectacles” of typical white-eyes. Birds in the montane regions of far western and far eastern Java have a dark patch between the eye and the base of the bill, and minimal white on the face (a full thin eyering in eastern birds, and a white crescent under the eye in western birds), while birds in central Java have a large but poorly-defined white patch around the eye. Forages actively in wooded and forested areas from foothills to mountaintops, often in pairs or groups. Joins mixed-species flocks. Song is a bright series of whistled notes; calls include rattling, high-pitched “tchrr”s and sharply falling whistles.
