Ladder-tailed Nightjar
Hydropsalis climacocerca
Large nightjar of tropical lowlands, often found near waterways. Sandy brown with indistinct light markings and a fairly long tail; in flight, males show large white wedges on outer tail feathers. Roosts during the day in vegetation along the edges of oxbow lakes and rivers and forages around sandbars and river edges at night. Does not call often, but occasionally gives soft chirping calls in flight.

Range and habitat
The ladder-tailed nightjar is found in all regions of the Amazon basin, and in the northeast the Guiana Shield and the Guianan countries; its range does not extend east of the Amazon River outlet, (the island: Ilha de Marajo). At this same outlet, in the region of the Xingu River confluence, the range extends southward and is in the lower two-thirds of the drainage of this north-flowing river.<p>In the west the species range is adjacent to the Andes foothills. In the north, the range extends into southeastern Venezuela, and only the upper third of the Caribbean north-flowing Orinoco River drainage, the area of the eastern Orinoco River Basin and uplands bordering western Guyana.<p>In the very headwaters of the southern Amazon Basin, the upstream half of the river drainages, both in the southeast and southwest, the range overlaps with its sister Hydropsalis species, the scissor-tailed nightjar, which ranges into southeast Brazil through the caatinga, cerrado, and pantanal south into Argentina. The two species cover all of South America east of the Andes cordillera from central Argentina to the Caribbean coast; the exception is a small region centered southeast of the Amazon basin in the vicinity of Maranhão, Brazil.

Rubeho Akalat
Sheppardia aurantiithorax
A rather small, demure understory denizen resembling a cross between a robin and a flycatcher. Mostly dull brown above, with an olive-brown crown and richer orange-brown underparts. Juvenile is more mottled. A highly local bird, found singly and in pairs in the understory of primary and secondary montane forest in a narrow range along the Rubeho and Ukaguru (and possibly Uluguru) mountains escarpment between 1800 and 2200 meters. Sits for long periods, sallying to catch insect prey, or forages on the ground, often in the company of ants and other ant-following birds. Sings a simple high-pitched “tsoot-tseeet-soo-seeet” and other similar songs. Calls include an invariable piping “wheet” uttered once a second. Alarm call is a grating, ticking “drrrzzt, drrrt, drrrt.” May be mistaken for a flycatcher, but its furtive nature and preference for thick understory are unique within its range.

Rwenzori Apalis
Oreolais ruwenzorii
Slim, pretty, long-tailed member of the cisticola family that sports gray upperparts and buffy underparts with a black chest band. Common in montane forest of the Albertine Rift. Usually in pairs or small groups, readily joining mixed-species flocks. Vocalizations include a ringing “svink” and a lower “veet” which are often given in duet by a pair. Not known to overlap in range with Black-collared Apalis, and differs in having a buffy rather than white throat, and no white in the outer tail.

Many-colored Fruit-Dove
Ptilinopus perousii
A spectacular dove with a red crown and shawl, a white face, a yellow neck, a yellow back with gray chevrons, a gray uppertail, a red undertail, and a flecked red breast. Often found in pairs, but can gather in large groups at fruiting trees. Female similar to female Crimson-crowned Fruit-Dove, but has a less reddish cap and a darker green neck. Gives two commonly heard calls, a typical pigeon-like cooing phrase likened to the words “let it go, let it go,” and a series of cooing notes that rapid increases in speed like a marble dropped on a hard surface.
