Roviana Rail

Small, short-tailed wren endemic to the Santa Marta Mountains of Colombia. It has a white eyebrow and streaky face, though plumage is almost identical to that of Gray-breasted Wood-Wren. It can be identified by its faster, squeakier, and higher-pitched song, and it generally occurs at higher elevations with little overlap. Usually found in pairs that stay low in cloud forest understory. Quite common in the upper parts of El Dorado Nature Reserve, but not found near the lodge.

A large, unusual bushshrike of Tanzania’s Uluguru Mountains with a huge bill, a black head, a green back, and yellow underparts. Found in the canopy of montane forest, usually in pairs. Most often detected by the distinctive and unusual voice, which consists of sliding whistles given in pairs, one lower and one higher, along with well-spaced ratcheting notes. These two vocalizations are usually synchronized as a duet by a pair. 

Large, chicken-like bird of humid lowland and foothill forest in western Ecuador and western Colombia. Brown with a gray head, yellow bill, and pink legs. Similar to Gray-cowled Wood-Rail but gray restricted to head. This rare and threatened species prefers swampy areas such as stream edges and mangroves, and is typically encountered in pairs. Shy and very hard to see. Usually first detected by it song, a very long, rollicking series of notes, often given by both members of the pair.
