Amazonian Parrotlet
Nannopsittaca dachilleae
Rare, short-tailed parakeet. Small and green, with a light bluish wash on the face. Sexes similar. Compared to the similar (and usually more common) Dusky-billed Parrotlet, note the absence of a blue rump patch (also missing on female Dusky-billed), bluish face (green or yellow in Dusky-billed), and light pinkish bill. Likes to feed on seeding bamboo, and most often found in areas with extensive bamboo or in secondary forest along rivers. Flight calls are high tinkles that are lower and less metallic than Dusky-billed Parrotlet calls.
识别特征
The upper parts, nape, auriculars, dorsum, tertials, wing covers, rump, upper-tail, and rectrices are bright green. The forehead, anterior crown, and ores are a pale blue. The malar area, breast, belly, and under-tail are a paler more yellowish green. No sexual dimorphism has been described as yet.[citation needed]
分类信息
The Manu parrotlet was discovered in 1985 by John P. O’Neill, Charles A. Munn, and Irma Franke while exploring the Manú River in the Manú National Park in eastern Peru. The new species was named after the scientists' colleague, conservationist and journalist Barbara D’Achille.<p>The generic name is from Latin nānus dwarf, from Greek nanos dwarf + Latin psittaca feminine of psittacus parrot, from Greek psittakos parrot; dachilleae a Latinized form of the surname d'Achille, hence the "dwarf parrot of d'Achille".[citation needed]

分布与栖息地
The bird has a patchy distribution throughout Brazil, Bolivia, and Peru, with the latter containing the majority of its population. It largely occupies riparian forests, especially those that consist of Calocophyllum spruceanum and Cecropia membranacea.[citation needed]

- Nomadic movement
行为
The bird was consistently measured to be in flocks of anywhere from 5 to 12 birds by the researchers who described it. Flocks make sounds similar to squawking or peeping. One possible nest was observed, a burrow among a cluster of bromeliads.[citation needed]<p>It generally tends to forage on the ground for seeds or in mineral deposits left by rivers, especially on the seeds left behind by bamboo in the genus Guadua.<p>Another important source of nutrients for the Manu parrotlet is the clay licks, narrow horizons exposed to a vertical bank on a riverbed to consume sodium and other minerals that are depositeted there. The Manu parrotlet appeared every two or three days about midday with groups of dusky-billed parrotlet (Forpus sclateri), tui parakeet (Brotogeris sanctithomae), and cobalt-winged parakeet (B. cyanoptera), with the Manu parrotlet eating clay for about 30 minutes.
保护状况
The Manu parrotlet faces primarily habitat fragmentation and degradation from industry, especially mining, and associated roads.

Black-capped Antwren
Herpsilochmus atricapillus
Small, long-tailed antwren of the middle to upper levels of woodlands and dry forests. Males are gray with a contrasting black cap and eyebrow. The tail is black and white-tipped and the wings are black with white bars. In females note the cinnamon forehead, gray back and buff belly. The song is loud and usually given as a duet.
Black-chested Mountain Tanager
Cnemathraupis eximia
A large and scarce tanager of montane forest in the high Andes from extreme western Venezuela to extreme northwestern Peru. Unlikely to be mistaken with a good view: dark hood (blue on the crown and nape, black on the throat) with a green back and yellow belly. Also note blue shoulder and green edging on wing feathers. Less common than Hooded Mountain-Tanager, which has a blue back and red eye. Pairs or small groups forage quietly in the lower to middle levels of forest and edges, often apart from mixed flocks. Occurs from 2,800 to 3,700 m.
Black-faced Firefinch
Lagonosticta larvata
An unusual and distinctive firefinch with very different male and female plumages. Males have a black face, while the color of the underparts varies geographically from pale gray to pale pink to rosy red. Females are mostly gray-brown with a reddish tint to the underparts and a pale undertail. Generally uncommon in woodland, grassland, and thickets, often near water. Sometimes mixes with other waxbills. The female is similar to other female firefinches, but is separated by its combination of a pale undertail and dark bill. The common calls are soft, repeated whistles.
