Purus Jacamar
Galbalcyrhynchus purusianus
Distinctive dark jacamar with a heavy bill and short tail. Deep chocolate brown, with a pinkish bill and reddish skin around the eye. Sexes similar. Forages in pairs and groups in trees around marshes, including around the edges of oxbow lakes. Its call is a piercing whistled “PEER”; Paradise Jacamar has a similar but weaker call.
识别特征
The Purus jacamar is 20 cm (7.9 in) long and weighs 50 g (1.8 oz). It is stouter than many jacamars, and has a more robust bill. It is almost entirely chestnut, with dark bronzy forehead, crown, wings, and tail. The juvenile is paler and its bill is shorter.
分类信息
The Purus jacamar shares genus Galbalcyrhynchus with the white-eared jacamar (G. leucotis). They were originally treated a separate species, then as conspecific ("chestnut jacamar"), but are now understood to be separate species. The Purus jacamar is monotypic.

行为
The Purus jacamar preys on insects, with Hymenoptera (bees and wasps) and Isoptera (termites) favored. It perches at mid- to upper canopy height singly or in small groups and sallies out to capture its prey.<p>The Purus jacamar has been documented excavating cavities in termite nests high in trees in Brazil and Peru. It is apparently a cooperative breeder, as the Peru cavity was excavated by six individuals and groups of up to six individuals have been noted singing together.<p>The Purus jacamar's vocalizations are essentially identical to those of white-eared jacamar. The song is a rising trill [1] and the calls "a series of loud 'peeeur' whistles and a sharp 'pee'” [2].

Junin Tapaculo
Scytalopus gettyae
Poorly known Peruvian endemic found only in high Andean cloud forest northeast of the city of Huancayo. It was described to science in 2013. Adult male is plain gray, lacking the rufous barring on the lower underparts shown by Rufous-vented Tapaculo and Trilling Tapaculo. Female plumage not yet known with certainty. Younger birds are heavily marked with bars or scales. Best identified by range and voice. Typical song is a lengthy series that starts out with simple notes and gradually transitions into sputtering bursts.
Bar-winged Oriole
Icterus maculialatus
Very local, poorly known black-and-yellow oriole of Chiapas and northern Central America. Favors brushy oak woodlands and semi-deciduous scrubby areas, especially with oaks. Associates with other orioles at flowering and fruiting trees, but often remains inside cover and thus easily overlooked. Male is the only yellow-and-black oriole in its range with a white wingbar. Female and immature resemble Black-cowled Oriole (usually not in the same areas), but wings grayish (not contrastingly blackish) with narrow whitish wingbar.
Pale-billed Sicklebill
Drepanornis bruijnii
A large, long-billed bird of lowland forest. Brown upperparts with black head and grayish facial skin behind the eye. Note the curved, pale bill. Male has a black throat, sides and two small, hornlike tufts on the head. Female has pale underparts with dark barring. Similar to female Twelve-wired Bird-of-Paradise and Magnificent Riflebird, but female Pale-billed Sicklebill has a longer, thinner, more curved bill. One of several vocalizations, a descending series of low whistles, reminiscent of Common Potoo.
