Coppery-bellied Puffleg
Eriocnemis cupreoventris
Fairly large hummingbird found in the Andes of northern Colombia and western Venezuela. Glittering green overall with a coppery belly, puffy white feathers at the base of the legs, and bright sapphire undertail coverts. Sexes similar. Occurs in high elevation montane forests, shrubby woodland, and páramo; occasionally visits feeders.
Identification
The coppery-bellied puffleg is 9 to 10 cm (3.5 to 3.9 in) long and weighs 4.4 to 5.6 g (0.16 to 0.20 oz). It has a straight black bill. The male has shining green upperparts with bluish green uppertail coverts. Its throat, breast, and flanks are glittering green, the center of its belly golden-copper, and its undertail coverts glittering violet. Its leg puffs are white. The tail is forked and blue-black. The female is similar, but its throat has grayish white speckles and the coppery belly is less intense. The juvenile has a blackish breast and no copper on the belly.

Range and habitat
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).

Behavior
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-rumped Swiftlet
Aerodramus spodiopygius
A small, mostly gray swiftlet, paler beneath with a pale throat and darker cap. White rump varies from white to pale gray. Occurs over a wide range of habitats up to 1900 meters of elevation. Similar to both Uniform Swiftlet and Mayr’s Swiftlet, but smaller, with a paler rump. Main call is a pleasant twitter, “twee-twee-chew-chew.”
Swallow-tailed Kite
Elanoides forficatus
A graceful, uniquely shaped raptor with long, narrow wings and deeply forked tail. Black-and-white with shining blue-gray upperwing. Usually seen in flight as it soars and glides while twisting its tail. Wingbeats are deep, fluid flaps. Found over a variety of wooded habitats with a preference for wetter habitats around rivers and ponds. Feeds mainly on insects captured on the wing.
Cameroon Indigobird
Vidua camerunensis
A nest parasite that lays its eggs in the nests of African and Black-bellied Firefinches and Brown and Dybowski's Twinspots. Breeding males are glossy black with blue iridescence and a pale brownish panel in the wings. Females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The bill is whitish and the legs very pale purplish. Found locally in lush woodland, savanna, and cultivated areas. Given current knowledge, can only be confidently identified by mimicked vocalizations. Each male parasitizes only one of the four host species and imitates its vocalizations, often mixing them into a scratchy jumble of high-pitched notes.
