Tacarcuna Wood-Quail
Odontophorus dialeucos
This rare chickenlike bird has an exceptionally small range on the border between Panama and Colombia. Found on the ground in mature forest from around 1,000–1,400 m. Dark brown overall with a black head, a whitish face and eyebrow merging with a buffy nape, and a white band across upper chest. Lives in small groups, which can be difficult to see. Listen for the rollicking whistled song, typical of wood-quail.
识别特征
The Tacarcuna wood quail is 22 to 28 cm (8.7 to 11.0 in) long. Males are estimated to weigh 264 g (9.3 oz) and females 258 g (9.1 oz). Males' crown and throat are black and the supercilium, lores, and chin are white. The sides and back of the neck are cinnamon. The back and rump are olive brown with black vermiculation and the breast and belly are chestnut speckled with white. Females are similar but their underparts are more tawny brown. Juveniles are similar to the female but the white of the chin is smaller and the black of the throat broader.
分类信息
Some authors have suggested that the Tarcarcuna wood quail and gorgeted wood quail (Odontophorus strophium), Venezuelan wood quail (O. columbianus), black-fronted wood quail (O. atrifons), and black-breasted wood quail (O. lecuolaemus) are actually a single species, but this treatment has not been accepted by the major avian taxonomic systems. The species is monotypic.

Yellow Flycatcher
Erythrocercus holochlorus
A small and colorful flycatcher with olive-yellow upperparts and yellow underparts. Found in lowland forest, mostly in the canopy. Often joins mixed-species flocks. Somewhat similar to yellow-warblers, but much smaller and found in different habitats. Similar to Livingstone’s Flycatcher, but there is very little overlap in range, and can easily be separated by the olive-green rather than rufous tail. Vocalizes frequently, giving high-pitched, chittering calls and a quick whistled song.
Eastern Miombo Sunbird
Cinnyris manoensis
A medium-sized typical ‘double-collared’ sunbird. Larger and longer-billed than similar-plumaged Western Miombo Sunbird (and ranges hardly overlap); Eastern Miombo male has broader red breast band, darker gray belly, and less prominent yellow wingpit tufts. Female and immature have a gray-brown head, pale gray throat, and pale lemon breast and belly. Singles and pairs are residents and nomads in Miombo woodland, gallery forest, arid savanna, and other woodland. Sings a slower, louder, less rambling song than Western Miombo Sunbird that does not end in a long descending trill.
Black Tinamou
Tinamus osgoodi
Large, rare tinamou found in cloud forest along the east slope of the Andes. It is uniformly sooty gray, much darker and plainer than Gray Tinamou. Rusty lower underparts are hard to see in the field. Like other forest tinamous, it is far more likely to be heard than seen. Vocalizations include a low, drawn out coo, like a dove’s but longer, and a series of low, modulated whistles.
