分布与栖息地
The coppery-bellied puffleg is found from the Andes of northwestern Venezuela's Mérida state south and west in the Eastern Andes of Colombia as far as Cundinamarca Department. It mostly inhabits open landscapes such as the edges of montane forest, shrubby slopes, and the lower reaches of the páramo zone, though it also occurs inside humid forest. In elevation it ranges between 2,000 and 3,000 m (6,600 and 9,800 ft) but is most abundant above 2,500 m (8,200 ft).

行为
The copper-bellied puffleg is mostly sedentary but makes seasonal elevational movements.<p>The coppery-bellied puffleg feeds on nectar at shrubs and small trees whose flowers have short corollas. Some preferred plants are those of genera Palicourea, Cavendishia, and Pernettya. It nectars while clinging to the flower and is "pugnacious and territorial" at flowering plants. Its diet also includes insects taken by hawking.<p>The coppery-bellied puffleg's breeding season is from September to January. Its nest has not been described but is usually placed in dense vegetation. The female incubates the clutch of two white eggs but the incubation period and time to fledging are not known.<p>The coppery-bellied puffleg's only described vocalization is "a single metallic note 'tseek', repeated at irregular intervals". It is given both from a perch and while hovering.

White-browed Piculet
Sasia ochracea
Minute woodpecker of lowland and foothill forests, where it forages in areas with dense low vegetation at the lower and middle levels. Predominantly rusty orange, with an olive-green crown and wings and a small but bright white eyebrow; the very similar Rufous Piculet lacks a pale brow. Male White-broweds have a bright yellow patch on the forehead which females lack. Often solitary, but can be found in small flocks and mixed-species foraging groups. Gives an explosive, squeaky, often descending chatter and sharp “chip” notes.
Plain Sunbird
Anthreptes simplex
A medium-large sunbird with a rather thick, slightly decurved bill. Extremely plain: pale olive-yellow above and paler washed-out yellow below. Male has a small black “shield” on his forehead which the female lacks. Female readily distinguished from female Brown-throated and Red-throated Sunbirds by her unmarked face. Inhabits a wide range of forest types from lowlands into foothills but seems to favor coastal forest and forest edge. Forages and moves actively, like a warbler, gleaning insects from the foliage. Gives plaintive “tseee”s and “tsi”s.
Greater Bird-of-Paradise
Paradisaea apoda
A large bird of lowland and foothill forest and edge. Male has a black breast and white and yellow plumes which he raises above his back during his display, in which he variably hops about and flaps his wings, then holds them out still. May overlap slightly with Lesser and Emperor birds-of-paradise but male Greater is larger and lacks a yellow back. Female Greater is distinguished from other species by its all brown body. Male gives a typical, repeated nasal squawk.
