Pirre Hummingbird
Goldmania bella
Rare and poorly-known hummingbird with extremely limited range near the border of Panama and Colombia. The most distinctive feature on this medium-sized hummingbird is the pale rufous outer tail feathers, present on both males and females. Also note small cinnamon patch on wings. Male has glittering blue-green throat. Female is paler below with a cinnamon wash on throat. Occurs in the foothills and highlands, usually in the lower to middle levels of forest.
识别特征
The Pirre hummingbird is 8.4 to 9.5 cm (3.3 to 3.7 in) long. Males weigh about 3.0 to 3.5 g (0.11 to 0.12 oz) and females 3.0 to 4.0 g (0.11 to 0.14 oz). Both sexes have a slightly decurved bill with a black maxilla and a black-tipped pink mandible. The male has a chestnut forehead and lores. Its crown, back, rump, and uppertail coverts are metallic green; the lower back and rump have a bronzy cast. Its central pair of tail feathers have bronze green bases and black tips and the rest are cinnamon buff with black tips. Its chin is cinnamon buff, the throat, breast, and belly shiny bluish green, and the undertail coverts white. Females have entirely green upperparts without the male's chestnut forehead. Their lores are chestnut and their underparts pale cinnamon buff.
分类信息
The Pirre hummingbird was first described by Edward William Nelson in 1912 from specimens collected near Cana and the slopes of the Cerro Pirre in the Darién National Park in eastern Panama near the border with Colombia. Nelson coined the binomial name Goethalsia bella. A molecular phylogenetic study published in 2014 found that the Pirre hummingbird was closely related to the violet-capped hummingbird (Goldmania violiceps). Most taxonomic systems moved the species into Goldmania, which has priority. However, BirdLife International's Handbook of the Birds of the World retains it in Goethalsia.<p>The Pirre hummingbird is monotypic: No subspecies are recognised.

分布与栖息地
The Pirre hummingbird is found on a few isolated ridges in Panama's eastern Darién Province and in adjacent Chocó Department in Colombia. It inhabits the understory of the edges and interior of humid montane forest at elevations between 600 and 1,650 m (2,000 and 5,400 ft).

行为
The Pirre hummingbird's movements, if any, have not been documented. <p>The Pirre hummingbird forages for nectar from near the ground to the middle levels of the forest. Its diet has not been described in detail but it has been observed feeding at Cephalus shrubs. In addition to nectar it is assumed to also feed on small arthropods like other hummingbirds. <p>Nothing is known about the Pirre hummingbird's breeding phenology and its nest has not been described. <p>The Cornell Lab of Ornithology's Macaulay Library and xeno-canto have very few recordings of the Pirre hummingbird's vocalizations. It does make "a single sharp note repeated in a long series" while perched but its function is not known.

Finch-billed Myna
Scissirostrum dubium
A distinctive ashy-gray starling with a conspicuous, bulbous pale bill and fine red flecks on the rump. Juvenile browner, with orange coloring to rump and paler bill. Highly gregarious and vocal, often observed in flocks of dozens, frequenting the canopy. A species of lowlands and hills, preferring open woodlands and forest edge, particularly favoring tall dead trees, where they nest communally in cavities. Restricted to Sulawesi and nearby islands. Vociferous, regularly uttering “chirup” calls, typically as a large, noisy group.
Black-backed Cisticola
Cisticola eximius
A tiny, short-tailed, streaky cisticola. Note the rufous rump and variably rufous flanks. Breeding male has an unstreaked rufous crown. Female and non-breeding male have a paler brown crown with dark streaks. Found locally in short grassland, especially in seasonally flooded areas. Inconspicuous for most of the year. Usually seen when doing a flight display over its breeding habitat. Very similar to several other cisticolas, though usually distinguished by range. Zitting Cisticola overlaps widely in range, but Black-backed is separated by voice, richer overall coloration, and shorter tail. The song consists of a series of raspy “chree” notes, sometimes given along with wing snaps. Also gives explosive scolding notes and high-pitched whines.
Olive-chested Flycatcher
Myiophobus cryptoxanthus
Drab and unremarkable flycatcher found in the eastern foothills of the Andes in Ecuador and northern Peru. Note grayish-olive upperparts, dingy white underparts, yellow tinge to the belly, and pale wingbars. Yellow crown stripe is usually concealed. Habitat is a good ID clue: it perches low in grassy clearings with scattered bushes and small trees, and never ventures inside forest. Call is an inflected whistle repeated every few seconds, and song is a short, rising trill.
