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.

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]

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.

Tasmanian Scrubwren
Sericornis humilis
Small gray-brown bird with black-and-white shoulder patch, dull white eyebrow, and faint pale chin stripe. Very similar to White-browed Scrubwren but darker and has less obvious facial pattern. Endemic to Tasmania and some surrounding islands. Forages on the ground in a variety of habitats with thick vegetation.
White-flanked Antwren
Myrmotherula axillaris
Very small, active forest bird, rather plump and short-tailed. Male is blackish with obvious white flank and white spotting on wing. Female is pale grayish-brown with buffy spotting on wing; white flanks are usually still obvious. Typically found in pairs, often following a mixed-species flock through the forest, foraging among dead leaf clusters and tangles. Stays at lower or middle levels.
Golden-collared Tanager
Iridosornis jelskii
Beautiful, fairly large tanager. Dark blue above, rusty red below, with a black head and bold yellow hood. Sexes similar. Inhabits elfin forest and humid scrub around and above the treeline, where it is often found in mixed-species flocks with flowerpiercers and other tanagers.
