Red-billed Tyrannulet
Zimmerius cinereicapilla
Small and rather scarce flycatcher found in disturbed forest on the east slope of the Andes. Yellowish-olive with a gray head and pale throat. Combination of stubby, reddish bill, pale iris, and yellow edges to wing feathers that do not form distinct wingbars help separate it from other small flycatchers. Overlaps with the very similar Mishana Tyrannulet in northern Peru, but Red-billed has a gray (not olive) crown and a different voice. Calls include soft whistles and squeaks, given alone or in a quick series. Typically seen perched high in a tree in a clearing or at forest edge.

Southern Crested Guineafowl
Guttera edouardi
A large-bodied, small-headed, black gamebird perfectly lined with rows of hundreds of bluish-white spots. It has a ridiculous-looking plumed “toupee” above the naked face, which features an ivory-colored bill and a blood-red eye. The facial skin color varies geographically, and can be mostly blue-gray with small patches of red and white, or predominantly blue-gray with a large white patch on the back of the neck. A broad band around the base of the neck is unspotted black. It prefers forest and thickets, where it forages on the ground for berries, seeds, and other plant matter. The similar Helmeted Guineafowl differs by its lack of feathered crest and its having a bone-like casque on top of the head instead. The alarm call is a series of rattling, agitated notes that speed up and slow down; similar to the call of Helmeted Guineafowl, but with a tinnier quality.
Black-throated Wren-Babbler
Turdinus atrigularis
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.
Plain-pouched Hornbill
Rhyticeros subruficollis
Medium-sized hornbill; resembles a smaller version of Wreathed Hornbill. Black with a white tail. Male has a white head and neck and a yellow throat pouch, while females have a blue pouch. Separated from Wreathed by lack of grooves on bill, small size, and lack of a black patch on the pouch (hence “plain-pouched”). Inhabits lowland forests; frequently detected flying powerfully overhead giving short, high-pitched calls. Often encountered in flocks.
