Chestnut-bellied Thrush
Turdus fulviventris
Handsome cloud forest thrush found mainly along the east slope of the Andes. Visitors from North America may be struck by its similarity to American Robin. No other thrush in range has a chestnut belly. Adults also have a dark hood, yellow bill, and yellow eyering. Young birds lack the dark hood and have mottled underparts. Uncommon and usually encountered feeding in fruiting trees; rarely comes down to the ground.
识别特征
The chestnut-bellied thrush grows to a length of about 25 cm (10 in). The adult male has a black head, a black throat with some white streaking, a dark grey back and dusky wings and tail. The upper breast is pale grey and the lower breast and belly are rufous. The beak is yellow, the narrow eye ring is orange and the legs are dull yellow. The female is similar in appearance but rather duller. It is the only thrush in the genus Turdus with a rufous belly to be found in the northern Andes. The song is not often uttered, but consists of a series of disjointed phrases with some buzzes and short trills in between.

分布与栖息地
The chestnut-bellied thrush is native to northwestern South America. Its range includes western Venezuela, western Colombia, Ecuador, northern Peru and northwestern Bolivia. Its habitat is woodland and the canopy and edges of montane forests at altitudes between 1,400 and 2,600 m (4,600 and 8,500 ft).

行为
This thrush often occurs singly and may also be seen in pairs, but does not usually join mixed flocks. Males may sing from high in the canopy, and both sexes often forage among the twigs and branches. It sometimes descends to ground level, particularly besides roads and trails, and turns over the leaf litter, searching for invertebrates, and may remain in one area for some time.

Ayres's Hawk-Eagle
Hieraaetus ayresii
Small black-and-white eagle. Has a compact, powerful shape, and the hint of a crest. The upperparts are black, and there are heavy black markings on the underparts and evenly across the underwing. Found in thick woodland and forest. Soars frequently. Call is a loud, repeated “kwee-ya.” Similar to other hawk-eagles, but has more heavily marked underparts. Easily separated in flight, when Ayres’s Hawk-Eagle shows black barring across the entire underwing.
Nicaraguan Seed-Finch
Sporophila nuttingi
What this bird lacks in color, it makes up for with a ridiculously oversized bill. Male is all glossy black, female warm brown. Male’s bill is huge and pink, female’s is equally huge but dark gray. Larger overall size than other seed-finches and seedeaters. Could be mistaken for Thick-billed Seed-Finch but even larger bill should help with identification; also note lack of a white patch in the wing. Found in open habitats, especially fields with some scattered shrubs.
Capuchinbird
Perissocephalus tricolor
Large, bizarre bird of tall rainforest. Unmistakable even when seen briefly, as they often are, flying quickly across roads or rivers. Appears broad-winged and mostly burnt orange with a disproportionately small head. Feeds on fruit in the forest canopy. Far-carrying display call of lekking males is one of the strangest avian sounds, similar to a distant chain saw or cow; males on leks can seem almost oblivious to human observers.
