Dusky-green Oropendola
Psarocolius atrovirens
Medium-sized oropendola of montane forests. Evenly olive-green, with a dark eye and pale bill. Smaller than the similar Russet-backed Oropendola, with a darker olive head. Weaves hanging nests in small colonies, and is found most frequently around forest edges and flying above the canopy. Song is a variable jumble of liquid whistles and pops; listen also for its loud “chak” call notes.
识别特征
The male dusky-green oropendola grows to a length of about 42 cm (17 in) and the female of about 33 cm (13 in). The sexes are similar in morphology, the plumage being mainly dark brownish-green or blackish-green, with a rufous-brown rump and crissum (the undertail coverts surrounding the cloaca). The beak is greenish-white, there may be a few yellow feathers on the head, and the iris is brown or blue, the latter colour perhaps being in older birds. The russet-backed oropendola (Psarocolius angustifrons), which partly shares the same range, has more rufous upper parts, a yellow forehead and olive-green head which contrasts with its back and wings.

分布与栖息地
The dusky-green oropendola occurs on the east side of the Andes Mountains, its range extending from Huánuco Province in central Peru to Santa Cruz Department in Bolivia. It occurs in montane forests and near their edges at altitudes of between 800 and 2,600 m (2,600 and 8,500 ft) above sea level, mostly at greater elevations than the russet-backed oropendola.

Stierling's Wren-Warbler
Calamonastes stierlingi
Long-tailed brownish warbler. White below with clean dark barring. Found in broadleaf woodland: miombo, mopane, and Zambezi teak. Usually found in pairs or small groups. Often raises its tail in wren-like fashion. The song consists of three metallic notes, often repeated, reminiscent of a telephone ringtone. Similar to Barred Wren-Warbler, but found in different habitat, and the dark barring on the underparts contrasts more strongly with the white base color.

Frilled Coquette
Lophornis magnificus
Tiny hummingbird that is gray and green above and gray below. Like other coquettes it has a white bar across the rump. Males are astonishingly pretty with an orange crest, a ruff of white and green feathers on the neck, and a red bill with a black tip. Females have a white belly, and spotted throat, lacking the male’s crest and orange bill. Found at forest edges, in second growth habitats and in wooded savanna.

European Red-rumped Swallow
Cecropis rufula
Brightly-colored swallow with a deeply forked tail, pale orangish rump, black squared-off undertail coverts, an incomplete orange collar, and faint streaking below. Juveniles average paler and lack extensive orangish tones; may resemble house-martins but note deeply forked tail. Typically glides on stiff, flat wings, flying quite languidly with shallow wingbeats. Builds mud nests in mountains, on sea cliffs, and on buildings and other structures. Forages over open areas. Frequently gives a short, sparrow-like “twi’wit.” Very similar to African Red-rumped Swallow, but shows much heavier streaking below.
