Bolivian Tapaculo
Scytalopus bolivianus
Small, mouse-like bird found mainly in the Bolivian Andes. Despite the name, it also ranges over the border into far southeastern Peru, but does not reach Manu. The small white patch on the crown is distinctive, but can be hard to see from some angles and may be absent on some birds. Plumage is otherwise mostly grayish-brown with rusty barring on the lower underparts. Adult males are darker than females and juveniles. Does not occur together with the similar White-crowned Tapaculo. Inhabits the understory of humid forest, and usually very hard to see. Vocalizations include a long, very rapid trill and a slower series of sharp chips.
识别特征
The Bolivian tapaculo is 12 cm (4.7 in) long. Males weigh 17 to 22 g (0.60 to 0.78 oz) and one female weighed 19.5 g (0.69 oz). The male is mostly dark gray with reddish brown flanks, vent, and crissum (the area around the cloaca). It has a variable amount of white on the crown of the head. The female is paler gray washed with brown above with a black-barred brown belly. The juvenile is similar to the female.
分类信息
The Bolivian tapaculo was formerly considered a subspecies of rufous-vented tapaculo (Scytalopus femoralis) but was separated based principally on differences in their vocalizations.

分布与栖息地
The Bolivian tapaculo is found from Puno Province in southeastern Peru into Bolivia as far as Chuquisaca Department. It inhabits dense undergrowth in humid broadleaf forest. Its primary elevational range is 1,000 to 2,300 m (3,300 to 7,500 ft) but it can be found as high as 2,850 m (9,350 ft) in a few locations.

行为
No information is available on the Bolivian tapaculo's feeding or breeding phenologies. Its song is a trill up to 15 seconds long [1] and its alarm call is rendered "kekekeke" [2]. The female is thought to utter a high-pitched "brzk" [3].

Esmeraldas Woodstar
Chaetocercus berlepschi
Tiny hummingbird endemic to western Ecuador. Male has a violet throat, a green “vest” on otherwise white underparts, white spots on either side of the rump, and a thin, forked tail. Female lacks throat patch and has a rusty tinge to underparts, a black stripe through her face, and a shorter tail. Inhabits deciduous and semi-humid forest, especially in hilly areas near the coast. Undertakes seasonal movements that are not well understood, and is occasionally seen farther inland.
Scarlet-rumped Tanager
Ramphocelus passerinii
Fairly common in humid tropical lowlands. Favors evergreen forest edges, plantations, and verdant second growth, such as areas along roadsides. Forages mainly at low to middle levels often in fairly noisy small groups. Male is unmistakable if seen clearly: velvety black with a blinding scarlet rump. Female is very different: note distinctive bluish-white bill, tawny rump, and grayish head. Formerly known as Cherrie's Tanager and Passerini's Tanager.
