Sira Barbet
Capito fitzpatricki
Stunning and rarely seen bird known only from the remote Cerros del Sira range in central Peru, east of the main chain of the Andes. Easily identified by its scarlet crown, breast, and flanks as well as white throat and belly. Song is a quiet, low pitched gurgle; calls include guttural grunts and purring rattles. Usually seen in pairs or small groups foraging for fruit in the forest canopy. Discovered in 2008, this spectacular barbet was for a long time treated as a subspecies of Scarlet-banded Barbet. The two species do not overlap, and differ in the color of their flanks and thighs. Access to its known range is extremely difficult, and few birders have been lucky enough to see one.
识别特征
The Sira barbet is approximately 19.5 to 20 cm (7.7 to 7.9 in) long and weighs 70 to 79 g (2.5 to 2.8 oz). The adult male's crown and nape are crimson. It has a band of white, fairly wide at the shoulders tapering to the tail; the rest of the upperparts are black. It has a broad white supercilium and a black "mask". The rest of its face, throat, neck, and upper chest are white. A broad crimson band crosses the chest and extends along the flanks where it meets a variable amount of black or gray. The rest of the underparts are white. The female's plumage has minor differences from the male's. The Sira barbet is distinguished from the scarlet-banded barbet by differences in morphology and plumage, particularly the color on the bird's flanks, lower back and thighs, and it has a wider, darker scarlet breast band. DNA sequencing was also used to confirm the Sira barbet's status as a distinct species.
分类信息
The Sira barbet was discovered in 2008 and formally described in 2012. The International Ornithological Committee (IOC) has accepted it as a valid species. However, the South American Classification Committee of the American Ornithological Society (AOS) and the Clements taxonomy list it as a subspecies of scarlet-banded barbet (Capito wallacei). The Cornell Lab of Ornithology's Birds of the World acknowledges that the "Sira" form is significantly different from the nominate and suggests that it be accorded species rank.<p>The bird's epithet commemorates John W. Fitzpatrick, an expert for the Peruan avifauna and director of the Cornell Lab of Ornithology.

分布与栖息地
The Sira barbet is found only on the eastern slope of the southern Cerros del Sira, Ucayali Department, Peru. Eight specimens were collected from the upper Río Shinipo .mw-parser-output .geo-default,.mw-parser-output .geo-dms,.mw-parser-output .geo-dec{display:inline}.mw-parser-output .geo-nondefault,.mw-parser-output .geo-multi-punct,.mw-parser-output .geo-inline-hidden{display:none}.mw-parser-output .longitude,.mw-parser-output .latitude{white-space:nowrap}10°31′48″S 74°07′12″W / 10.53000°S 74.12000°W / -10.53000; -74.12000 (Río Shinipo) and Río Tzipani valleys 10°41′24″S 74°05′56″W / 10.69000°S 74.09889°W / -10.69000; -74.09889 (Río Tzipani), and a further two at Quebrada Quirapokiari 10°25′12″S 74°09′00″W / 10.42000°S 74.15000°W / -10.42000; -74.15000 (Quebrada Quirapokiari) in July 2011. Its range is sympatric and syntopic with that of the gilded barbet, and coincides with the boundary and sections of the Sira Communal Reserve.<p>It primarily inhabits the highest stratum of tall (up to 30 m (98 ft)) montane forest with arboreal epiphytes and moss above a sparsely vegetated understory. It is also found in shorter forest with a thicker understory. In elevation it ranges as high as 1,700 m (5,600 ft) but is mostly found between 950 and 1,250 m (3,120 and 4,100 ft).

Palau Swiftlet
Aerodramus pelewensis
A small, mostly uniformly light brown swiftlet with a slightly darker cap, a cinnamon-tinged throat, and a lightly forked tail. Occurs on larger islands, especially over highland ridges and gorges. Similar to Mariana Swiftlet but much paler, and differs from all other Micronesian swiftlets in its pale rump. Calls are primarily a series of insect-like buzzing and chirping.
Band-bellied Crake
Zapornia paykullii
Skulky and difficult to see, this medium-sized crake is often detected through its unique song, a hollow hoot-knocking that can be likened to a wood rattle or rapidfire tapping on a tiny high-pitched drum. Favors extremely well-vegetated marsh margins, often in areas with bushes and short trees, and sometimes near cultivation. If seen well, note dull gray-brown back, orange face, throat, and chest, and black-and-white striped sides. Ruddy-breasted Crake can be very similar, but note Band-bellied’s grayer back, duller red legs, more extensive white barring on the sides, and white-striped coverts (not always visible).
Spotted Antbird
Hylophylax naevioides
Stunning antbird, small and boldly patterned. Rotund and short-tailed. Male has white belly with band of black spots across chest, gray head, and rufous back. Female more washed out, but similar pattern. Usually seen singly or in pairs in understory of forest, often following a mixed flock or army ant swarm. Stuttered song is a series of slightly wheezy whistles, descending in pitch.
