Bannerman's Shearwater
Puffinus bannermani
A small black-and-white shearwater with relatively broad wings and a long rounded tail. Underwing very white, contrasting with darker smudgy marks along the leading edge of the wing. Two dark smudge marks are often visible at the collar, extending down from the hood. Somewhat similar to Bryan’s Shearwater, but much larger, and white does not extend above the eye, creating a darker-faced appearance. Also lacks the distinctive rapidly fluttering flight of Bryan’s.

Jungle Nightjar
Caprimulgus indicus
Gray-brown nightjar of wooded, open grassy, and scrubby areas; not restricted to jungles. Intricately patterned, with a golden patch behind the ear (often not visible on a resting bird) and pale tan spots on the wings. Male shows bright white patches near the wingtips and on the edges of the tail that are buffy-brown in females. Similar Savanna Nightjar is much more densely patterned and lacks the tan wing spots; Savanna also tends to roost on the ground, versus in trees for Jungle Nightjar. Song is utterly alien-sounding and unique: a long series of bouncing “pooKIHpooKIHpooKIH” notes, comparable to a cartoon laser gun.
Black-browed Triller
Lalage atrovirens
A medium-sized bird of lowland and foothill forest canopy. Black upperparts with white in the wing and a white rump in the male, white underparts with barring in the female. Limited geographical overlap with White-winged triller, but should be separated by habitat, with Black-browed in forest rather than open habitats. Voice includes various whistles, chips and a musical, rolling chatter.
Buff-browed Chachalaca
Ortalis superciliaris
Small chachalaca, brown overall with a pale buff eyebrow. Found in edge habitats, thickets, and young second-growth forests, even at the edge of urban areas. Song is typical of a chachalaca: a noisy, high-pitched, raucous “TJURRE-wruh,” repeated continually.
