Emerald-bellied Puffleg
Eriocnemis aline
Small, glittering hummingbird found in cloud forest along the east slope of the Andes. It is shining green with white leg puffs and has an irregular white patch on the underparts that is variable in size. Underparts may shine iridescent blue at certain angles in good light. Sexes similar. Uncommon inside humid forest at middle elevations, occasionally coming into clearings where there are abundant flowers or feeders.
识别特征
The emerald-bellied puffleg is the smallest puffleg. It is 8 to 9 cm (3.1 to 3.5 in) long and weighs 4.0 to 4.5 g (0.14 to 0.16 oz). It has a straight black bill. The male of the nominate subspecies has dark shining green upperparts with a narrow glittering bluish green forehead. It has a large white patch with green spots on its upper breast and the rest of the underparts are glittering bluish green. The tail is short and slightly forked; it is green with a markedly iridescent underside. The female is similar but without the bluish green forehead; its wings and tail are somewhat shorter. Both sex's leg puffs are white and very large. Subspecies E. a. dybowskii is larger than the nominate but the male's forehead patch is smaller and the white breast is less sharply defined.
分类信息
The emerald-bellied puffleg has two subspecies, the nominate E. a. aline and E. a. dybowskii. It is closely related to the colorful puffleg (E. mirabilis) and they have variously been deemed sister species or superspecies. However, one author has suggested that because their plumage is so different from that of other Eriocnemis pufflegs that they should have their own genus.

分布与栖息地
The nominate subspecies of emerald-bellied puffleg is the more northerly. It is found in Colombia's Central and Eastern Andes from Boyacá Department south through Ecuador on the eastern slope of the Andes. E. a. dybowskii is found on the eastern slope of the Peruvian Andes as far south as the Department of Pasco. The species inhabits tropical and subtropical montane forest, especially humid types like cloudforest. It occurs in the forest interior and small openings but shuns forest edges and more open landscapes. In elevation it is usually found between 2,300 and 2,800 m (7,500 and 9,200 ft).

Emerald-chinned Hummingbird
Abeillia abeillei
Very small, short-billed hummingbird of humid evergreen and pine-evergreen forest in highlands and upper foothills; uncommon. Usually feeds low, often at banks of flowers along edges and roadsides. Feeding flight is usually quick and hard to follow. Best identified by small size, big white spot behind eye, and rather liquid twittering call (similar to Stripe-tailed Hummingbird, which occurs in the same areas but looks quite different).
White-browed Coucal
Centropus superciliosus
A large, robust, ungainly cuckoo with rufous wings and a long, broad tail. Shows a solid dark cap and back of the head, and white underparts. Unlike other coucals, shows an obviously barred rump and upper tail coverts. It often moves clumsily, preferring to clamber about in rank vegetation or walk on the ground foraging for insects or small vertebrates. Its flight is labored and heavy. This species uses a wide variety of habitats with a thick understory, including savanna, woodland, forest edge, and wetlands. The song is a deep descending bubbling series, “bu-bu-bu bu bu bu bu”, that falls and then rises in pitch.
Bar-backed Partridge
Arborophila brunneopectus
An earth-colored partridge with a black throat and white cheeks. Most similar in appearance to White-cheeked Partridge; look out for a longer, much thicker white brow which extends down to the neck and a reddish patch of bare skin encircling the eye. Fine dark barring on the back isn’t as noticeable as bold black-edged white scaling on the flanks. Often found in drier forested habitats than other partridges, ranging from lowlands into the foothills.
