Levaillant's Cuckoo
Clamator levaillantii
A large, dark-backed cuckoo with a floppy crest, white wing patches, and pale underparts; throat and lower flanks both heavily streaked. It is a brood parasite on babblers and other medium-sized birds. It calls a shrill “kreeeuu”, which is often followed by harsh chattering notes. Levaillant’s Cuckoo is similar to the smaller Pied Cuckoo, which lacks throat streaking and has a smaller crest. Dark morphs of both species are almost identical and can only reliably be told apart by size.
Identification
The cuckoo is 37.5 cm (15 in) long, longer tailed than pied cuckoo, and with a more heavily streaked throat. There are two colour morphs. The light morph is black above, faintly glossed bluish or greenish. The throat streaking may extend on to the sides. The primaries and rectrix tips are white. The dark morph is black except for the white primary patch and white spots on the outer tail feathers (these are absent in dark pied cuckoo. The juvenile Levaillant's cuckoo is brown above, rufous on the wing-coverts and rectrix tips, with a buff forehead, face and underparts, and the throat more streaked. The call is a low ringing kuwu-weer, kuwu-weer... and an excited ku-wi-wi-wi.

Rothschild's Swift
Cypseloides rothschildi
Uncommon swift found along the east slope of the Andes from central Bolivia to northwestern Argentina. Uniform sooty brown, lacking any strong plumage characteristics. Easily confused with Sick’s Swift, but is larger with longer wings, giving it a sleeker and more aerodynamic appearance; also lacks a pale throat, though this is often hard to see clearly. In central Bolivia it could be mistaken for Chestnut-collared Swift (some of which lack a chestnut collar), but wings are slightly narrower at the base. Usually seen in flocks of a few birds up to 20 or more that circle over humid forest.

Guianan Puffbird
Notharchus macrorhynchos
Chunky, large-billed bird of rainforest canopy; easily identified by black-and-white plumage, relatively large size, and staid demeanor. Most often seen perched high in bare branches, sometimes near arboreal termite nests, in which it digs its own nest cavities. May also forage at lower levels. Sits motionless for long periods, sallying to vegetation for large insects. Superficially resembles Pied Puffbird but is much larger with a solid black crown and more white on the forehead.

Rufous-vented Tit
Periparus rubidiventris
An active and social small bird of broadleaf and mixed forests, usually in hilly regions. Thin, rather turnip-like crest is often held vertically. Gray with a black head marked by bright white cheek patches. May be confused with Coal Tit, but has a less wispy crest, lacks wingbars, and averages darker and more contrasting overall. Gives high thin calls, often heard as a flock whizzes overhead.
