Sapphire-vented Puffleg
Eriocnemis luciani
Large, lanky hummingbird of the high Andes; ranges from extreme southern Colombia south to Peru. Green with blue vent, white leg puffs, and fairly long tail. Birds from Ecuador have a blue forehead. Peruvian birds have little or no blue on the forehead, a coppery nape, and may show a bluish tinge on the belly. Sexes similar, though females from southern Peru can have a whitish belly. Encountered at edge of humid forest, aggressively defending flower patches.
Identification
The sapphire-vented puffleg is 11.4 to 14 cm (4.5 to 5.5 in) long and weighs 5.4 to 6.4 g (0.19 to 0.23 oz). It has a straight black bill. The nominate subspecies' male has metallic grass green upperparts with a shining dark blue forecrown. Its underparts are mostly glittering golden green with a glittering purple vent and undertail coverts. Its leg puffs are white and the tail is deeply forked and blue-black. The female is slightly smaller, with a less deeply forked tail, but has the same plumage.<p>Subspecies E. l. meridae is a more bronzy green than the nominate, its chin emerald to golden, and much of its head feathering has iridescent copper fringes. E. l. baptistae is an even deeper bronzy green than meridae. E. l. catharina has upperparts like the nominate but without the blue forecrown. The male's belly is bluer and the centerof the female's belly is whitish. E. l. sapphiropygia is a lighter green than the nominate, lacks the nominate's blue forecrown, and has a bronzy or coppery tinge to the rear of the crown.
Taxonomy
The International Ornithological Committee (IOC) and the Clements taxonomy recognize the following five subspecies of sapphire-vented puffleg.<p>BirdLife International's Handbook of the Birds of the World accepts several 21st century studies and treats the last two as members a separate species, the coppery-naped puffleg (E. sapphiropygia). The South American Classification Committee (SACC) of the American Ornithological Society declined to recognize that split.<p>Subspecies E. l. meridae is known only from the holotype that was collected in 1898, and it might be extinct.

Range and habitat
The subspecies of sapphire-vented puffleg are found thus (but see the text below):<p>Because E. l. meridae is known only from a single 19th century specimen and might be extinct, the SACC does not include Venezuela in the species' range. The SACC also notes that the species has been recorded as hypothetical (with "no tangible evidence") in Bolivia. There are several gaps in the distribution along the Andes that have not been explained.<p>The sapphire-vented puffleg inhabits humid montane forest, especially elfin forest and Polylepis woodlands, and is also found in brushy páramo. In Ecuador it ranges between 2,700 and 3,700 m (8,900 and 12,100 ft) of elevation, but occurs mostly below 3,400 m (11,200 ft). In Peru it occurs between 2,400 and 3,500 m (7,900 and 11,500 ft).

Behavior
The sapphire-vented puffleg forages for nectar at low levels, where it clings to the flowers of shrubs and understory plants. It has been documented feeding at mistletoes and also plants of genera Barnadesia, Embothrium, Bomarea, and Siphocampylus. It also feeds on small insects like other hummingbirds.<p>Little is known about the sapphire-vented puffleg's breeding phenology. The one described nest was made of moss, lichen, fern leaves, and spiderweb and was hung from a thin twig in dense grass. It contained two white eggs.<p>The sapphire-vented puffleg's call is described as a "sharp tirr tirr".

American Dipper
Cinclus mexicanus
Unmistakable plump passerine. Slaty-gray overall with a browner head. Juveniles are slightly paler below than adults. Forages for invertebrates by walking underwater. Inhabits fast-moving rocky streams in western North America, from Alaska to Panama. Often nests under bridges. Unique shape, behavior, and strict habitat preferences make American Dipper unlikely to be confused with any other species.
Green-bellied Hummingbird
Saucerottia viridigaster
Plain and often confusing hummingbird found along lower to middle slopes of the Andes. Note its limited range in the eastern Andes of Colombia and the Andes of Venezuela. Plumage is mostly green with rusty-brown rump and tail. Its name is deceptive as the belly is typically brown or buff, not green. Similar to Rufous-tailed Hummingbird, but bill is darker and less red, and rump and tail are browner and less rufous. Inhabits forest edge, clearings, and plantations. Birds found in the Tepui region are now considered a separate species, Copper-tailed Hummingbird.
Orange-breasted Bunting
Passerina leclancherii
Beautiful small bunting of lowlands and foothills; endemic to west Mexico. Occurs in brushy woodland and edge, adjacent weedy fields, and open grassy areas. Often in small groups, feeding on roadside grasses and flushing up with brilliant blue flashes. Also feeds at all levels in fruiting trees and bushes. Male unmistakable: electric turquoise blue and green above; rich yellow below with a burnished orange breast. Female duller overall: greenish above and yellow below, with a bluish tail. Female brighter yellowish below than slightly larger female Painted Bunting.
