Great Elaenia
Elaenia dayi
Very large brownish elaenia found only in the tepui region. Note the small, rounded head with only a vaguely crested look, and broken whitish eyering. Brown upperparts contrast with paler olive-gray underparts; also has pale wingbars. Typically found alone or in pairs, perching on the top of small trees and bushes. Occurs in scrub, forest edges, and savanna with small trees. Vocalizations are loud and variable; one common variation is a “SQUEE’ch’ch’ch-cheet-cheet” with both nasal and chattering notes. With a poor view can be surprisingly similar to Black-billed Thrush, but that species lacks wingbars and has a longer bill.

Black-billed Woodhoopoe
Phoeniculus somaliensis
An odd, long-tailed, slender-billed bird. Adults have a black bill, red legs, and blue or purple gloss when seen in good light. Found in dry country, often in fairly lush woodland along rivers. Always in groups, normally of 4-10 members. Similar to Green and Violet Woodhoopoes, but there is little overlap in range, and adults are separated by their black rather than orange bills. Immatures can be confusing, but are normally seen with adults. Also similar to Black Scimitarbill, but much larger, with a longer, floppier, and more triangular tail. The distinctive song starts with a rattling series, then builds into a maniacal cackling, given by a whole group in chorus.
Kinglet Manakin
Machaeropterus regulus
Chunky little, short-tailed bird of lowland and foothill forest. Male is distinctive with bright red crown and bold white stripes on reddish belly. Female lacks red crown but shows faint streaking on sides unlike any other manakin. Inconspicuous; elaborate display dance infrequently seen. Found in the lower to middle levels of forest. Listen for its strong “chew” call.
Niceforo's Wren
Thryophilus nicefori
Endangered songbird restricted to the western slopes of the northern part of Colombia’s eastern Andes. Note the white spectacles, striped face, and barred wings and tail. Very similar to the widespread Rufous-and-white Wren, but duller brown, lacking rich chestnut tones in the plumage, and its song tends to be faster and higher in pitch. Range is also helpful for ID, since the two species have limited, if any, overlap. Skulks in the understory of dry to semi-humid forest as well as in shady coffee and cacao plantations.
