Ocellated Piculet
Picumnus dorbignyanus
Gray, spotted piculet of mid-elevation forests. Dusky gray above and white below, with extensive black spotting from the head to the belly; males have a scarlet red forehead patch. Found at higher elevations than most other piculets in its range; grayer, with much more extensive black spotting, than the pale Fine-barred Piculet. Forages singly or in pairs in the mid-story of humid montane forest, sometimes joining mixed-species flocks. Its song is a very high, descending series of sharp, metallic notes.

The ocellated piculet is 9 to 10 cm (3.5 to 3.9 in) long and weighs 7 to 11 g (0.25 to 0.39 oz). Adult males of the nominate subspecies have a black cap with red tips on the forehead feathers and small white spots on the rest of the cap. Their face is mostly buff-brown with faint blackish bars and a white stripe behind the eye. Their upperparts are dull brownish, sometimes with faint whitish bars. Their flight feathers are dark brown with buffish white edges and tips. Their tail is dark brown; the innermost pair of feathers have mostly white inner webs and the outer two pairs have a white stripe near the end. Their chin and throat feathers are white tinged with buff and with dark edges or tips. Their breast and flank feathers are white with narrow black shafts and edges; their belly is buffy white. Their iris is brown, the orbital ring gray, and the legs gray. Their beak's maxilla is black with a blue-gray base and its mandible blue-gray with a black tip. Adult females are identical but for no red on the forehead. Juveniles are duller and darker than adults and have a sooty crown and diffuse barring on the upper- and underparts.<p>Subspecies P. d. jelskii is very similar to the nominate, but its breast feathers have wide black streaks on the shafts and fewer dark edges. Its forehead feathers have broader red tips.
分类信息
The ocellated piculet was first described in 1845 by the French ornithologist Frédéric de Lafresnaye as Picumnus d’Orbignyanus, named in honor of the French naturalist Alcide d'Orbigny. Since then the name has often been misspelled as P. dorbygnianus.<p>The ocellated piculet has two subspecies, the nominate P. d. dorbignyanus and P. d. jelskii (Taczanowski, 1882). However, the species' taxonomy and that of genus Picnumnus in general are uncertain. The two subspecies have at times been treated as separate species and also as subspecies of the white-barred piculet (P. cirratus). In addition, at times other subspecies have been attributed to it. The ocellated piculet is closely related to the white-barred piculet and the ochre-collared piculet (P. temminckii) and at times these species have been treated as synonymous. The ocellated piculet hybridizes with the white-barred piculet where their ranges overlap.

分布与栖息地
Subspecies P. d. jelskii of the ocellated piculet is found in central Peru between the departments of Huánuco and Cuzco. The nominate subspecies is found in western Bolivia and possibly into extreme northwestern Argentina. The Clements taxonomy and Cornell Lab of Ornithology's online Birds of the World include Argentina but the South American Classification Committee of the American Ornithological Society and the International Ornithological Committee do not.<p>The ocellated piculet inhabits the interior and edges of humid montane forest and mature secondary forest. It favors bushy undergrowth with vines, creepers, and epiphytes. In elevation it ranges between 800 and 2,400 m (2,600 and 7,900 ft) in Peru and from 900 to 3,300 m (3,000 to 10,800 ft) in Bolivia.

White-thighed Hornbill
Bycanistes albotibialis
A large canopy hornbill with a distinct white-tipped tail, a broad white outerwing with white patches within the black forewing, a white belly and vent, and a pale bill. Often seen in the canopy and subcanopy of lowland forest feeding on fruit. Call is a harsh series of caws, “hyr hyr hyr,” with occasional longer wails. Most likely to be confused with Black-and-white-casqued Hornbill, but White-thighed Hornbill has white on the vent and rump and on the tail tip, giving its tail a black-banded appearance, and its bill is pale.
Handsome Fruiteater
Pipreola formosa
A rotund, striking bird, medium-sized with green and yellow body and large white wing spots. Male has black head, yellow underparts, and blurred red chest patch; female lacks black head and shows yellowish underparts with green barring. Both sexes short-tailed with orange eyes and small orange bill. Often alone or in pairs, perching quietly in the low to high levels of the forest. Fairly common in humid forests in foothills or at higher elevations. Not as vocal as other fruiteaters. Female distinguished from Golden-breasted Fruiteater primarily by green barring (not streaking) on underparts. Endemic to the Coastal Cordillera of Venezuela.
Arfak Robin
Heteromyias albispecularis
A medium-sized bird of moist montane forest in the west of New Guinea. Pale gray below, pale pink legs, an indistinct white mark in the wing and an obvious white mark below the eye. Song a series of identical piping notes, delivered at variable pace.
