Coppery Metaltail
Metallura theresiae
Distinctively colored hummingbird restricted to treeline forest and scrub in the Andes of northern and central Peru. No other small hummingbird in its range has coppery plumage; also note the green throat (indistinct on female), short bill, and white spot behind the eye. Tail is faintly greenish underneath and bluish on top. Perches atop bushes when not feeding, and quickly chases away other intruding hummingbirds while giving rapid, high-pitched squeaks.
识别特征
The coppery metaltail is 10 to 10.5 cm (3.9 to 4.1 in) long and weighs about 5 g (0.18 oz). It has a medium length, straight, black bill. The adult male of the nominate subspecies has reddish bronze to reddish coppery upperparts with a greenish tone to the rump and uppertail coverts. Its slightly forked tail is bronze green with violet reflections on its upper side and shining bronze green on its underside. The sides of its head and neck are reddish bronze and its narrow gorget is glittering golden green. The rest of its underparts are a somewhat less reddish bronze green than the upperparts. The adult female is a duller version of the male and its gorget is smaller. Juveniles do not have gorget. Subspecies M. t. parkeri is similar to the nominate but its uppersides are not as reddish and the underside of its tail is a brighter golden green.

分布与栖息地
The nominate subspecies of coppery metaltail is found on the eastern slope of the Peruvian Andes from east of the Marañón River south into Huánuco Department. M. t. parkeri is known only from the Cordillera de Colán in Peru's Amazonas Department. Like most of the metaltails, the species inhabits the edges of elfin forest and páramo, moist landscapes characterized by shrubby growth and small trees. In elevation it ranges between 2,800 and 3,550 m (9,200 and 12,000 ft).

行为
The coppery metaltail is believed to be resident throughout its range.<p>The coppery metaltail feeds mostly on nectar but details of its diet are lacking. Males defend feeding territories. In addition to nectaring, it catches small arthropods by sallies from a perch.<p>The coppery metaltail's breeding phenology and nest have not been documented. Its breeding season appears to include August and September.<p>The coppery metaltail's vocalizations have been described as a "series of frail zeee calls, often alternating with ttrrrt notes" and also as "a jerky, wiry chatter similar to [that of] Tyrian Metaltail [Metallura tyrianthina], but perhaps lower, less emphatic, with buzzier notes."

Nashville Warbler
Leiothlypis ruficapilla
Small warbler with sharply pointed bill. Look for gray head, white eyering, yellow underparts (including throat), and olive upperparts. Sometimes pumps tail. Two disjunct breeding populations are very similar in appearance. Breeds in coniferous or mixed forests, often near clearings, second-growth, or bogs. In migration and winter, tends to be found in patchy woodland or brushy areas, including field edges and thickets. Winters primarily in Mexico. Listen for its loud chipping song, broken into two parts. Compare dull immature Nashville with Virginia’s Warbler; Nashvilles always have greenish wings. Also sometimes mistaken for larger gray-headed warblers like Mourning or Connecticut, but Nashville is much smaller, shorter-tailed, and sharper-billed.
Sjöstedt's Greenbul
Baeopogon clamans
A unusual dark greenbul often found near water in the forest interior. Decorated in various shades of dark and olive green, with a gray throat that contrasts with the breast, a buffy belly, and bright white sides of the tail. Can be confused with both Honeyguide Greenbul and actual honeyguides, but the flight is direct rather than undulating, the throat contrasts with the breast, the eyes are always dark, and the vocalizations are distinctive. Can be located by its “REHR!” calls, often followed by a series of fast, scratchy notes and sometimes repeated for minutes on end.
Brown-banded Antpitta
Grallaria milleri
Dingy-looking antpitta restricted to cloud forest in Colombia’s central Andes. Plumage is mostly brown with whitish throat and belly. Brown breast band is often very indistinct. Similar to Tawny Antpitta, but has a pale belly and inhabits forest. Like many other antpittas, it spends most of the time on the forest floor where it is normally very difficult to see in the gloom. It usually visits a feeder in the Rio Blanco Ecological Reserve near Manizales, where it is much easier to observe. Song is a three-note series, and each note is higher than the last.
