Balicassiao

Similar to many other species of jacamar: mostly glittering emerald-green with a rufous belly, long tail, and long pointed bill. Sexes are similar; female has a paler belly. Found in northwestern Amazonia, where pairs occur in the lower to mid-levels of mature lowland forest, often around water. Namesake white chin is not super conspicuous but usually visible. Also note brownish crown. Most similar to Bluish-fronted Jacamar, but apparently no range overlap.

Unique partridge of Java’s eastern highlands, where it inhabits primary forest from 500 to 2200 meters. Dark gray overall with a distinctive bright white face, which sets it apart from all other gamebirds in its limited range. Forages on the forest floor, often in small groups; typically quite shy, but can become accommodating at established feeding stations. Song is a slowly rising series of “whew” notes that eventually become a rapid, feverish, seemingly endless chant. Pairs often duet; one member will give the aforementioned song, while the other gives a lower, slower “woo-hoo.”

Uncommon wren-babbler of Bornean lowland and foothill forests. Like most other wren-babblers, secretive and difficult to locate as it forages on the ground, usually in small groups. Best detected by its song, which takes two forms. “Short song” is a repetitive series of ten or so clear, hooting whistles, while “long song” can be up to three or four times the length and interspersed with more rising and falling notes. Duetting birds will often add an additional song element, a mellow rolling series of notes along the lines of “dee-dee-dee-da-doo-da-dih-doo.” If seen, note black throat, pale bluish-gray patch behind the eye, black-edged streaking with a “scaly” appearance, and chestnut wings.
