Iquitos Gnatcatcher
Polioptila clementsi
Rare bird known only from the Allpahuayo-Mishana National Reserve in the lowlands of northeastern Peru. Like other gnatcatchers, it is mainly gray and white; tail is black with white outer feathers. Distinguished from female Tropical Gnatcatcher by gray breast and broken white eye-ring. Inhabits canopy of forests in areas with sandy soil. Typical song is three “sip” notes followed by a rapid trill.
识别特征
All of the specimens of Iquitos gnatcatcher have been immature, so the adult plumage has not been formally described. However, observations of apparent adults showed no differences from that of the immatures. The immatures were 11 cm (4.3 in) long and weighed 5 to 6 g (0.18 to 0.21 oz). The male's entire upper side from crown to rump is dark gray. It has a narrow, broken, white eye ring. Its throat and breast are medium gray and the belly white. The innermost feathers of its tail are black and the outermost approximately 80% white, with those between intergrading.
分类信息
The Iquitos gnatcatcher is a member of the Guianan gnatcatcher (Polioptila guianensis) complex. It was accepted as a new species by the South American Classification Committee of the American Ornithological Society (SACC/AOS) in July 2006 and by other taxonomic bodies at about that time. However, BirdLife International (BLI) recognizes it only as a subspecies of Guianan gnatcatcher.<p>Its specific epithet was chosen to honor the American ornithologist James F. Clements.

分布与栖息地
The only known population of the Iquitos gnatcatcher is the Allpahuayo-Mishana National Reserve, west of Iquitos, Peru. The reserve is "on [the] border of ecoregions characterized as Napo moist forest and Iquitos várzea. The elevation there is 150 m (490 ft).
行为
The Iquitos gnatcatcher's diet is not well known, but is assumed to be insects like that of other Polioptila gnatcatchers. It actively forages in the upper quarter of trees with mixed-species flocks, usually gleaning from the ends of branches and sometimes sallying out to catch flying insects.<p>"The nest, eggs, and breeding behavior of Iquitos Gnatcatcher remain undescribed."<p>The Iquitos gnatcatcher's song is "a distinctly two-part series" [1]. It also has a variety of calls.

Brown Fish-Owl
Ketupa zeylonensis
Huge bulky brown owl with a finely streaked breast, a plain face, and bright yellow eyes. Also note its dirty white “bib” and the heavy brow that gives it a moody demeanor. Inhabits waterside wooded areas from lowlands up into the mountains; feeds by dropping down into and wading around in creeks, lakes, and pools. Often gives deep echoing hoots, as well as various shrieks and higher-pitched hoots.
Congo Martin
Riparia congica
A typical small martin with brown upperparts, pale underparts, and a diffuse gray-brown breast band. Resident and extremely localized, restricted to the Congo River and a handful of its tributaries, breeding colonially in sandbanks. Despite being fairly common, the species’ vocalizations are unknown. Sand Martin is larger than Congo Martin and has a bolder breast band delineating a white throat; Brown-throated Martin has a dark throat.
Golden Bush-Robin
Tarsiger chrysaeus
Shining and distinctively yellow robin of the montane forest understory. Male sports a blazing golden brow, yellow underparts, and a black face. Female is less contrastingly patterned, but still noticeably yellow, with browner underparts and a white eyering. Both sexes have a yellow panel on either side of the tail. Song is composed of rolling, buzzing notes; it is not as melodic as those of some other bush-robins.
