Golden-breasted Puffleg
Eriocnemis mosquera
A fairly large hummingbird of high-elevation forest in the Andes in Colombia and Ecuador. Mostly green with an obvious golden sheen on the breast and white puffs on each leg. Long forked tail is greenish-bronze (not blackish or bluish). Sexes alike. Occurs from around 3,000–3,600 m, where it can be found in forest and edges. Visits feeders.
识别特征
The golden-breasted puffleg is about 11 to 13 cm (4.3 to 5.1 in) long and weighs about 5.3 g (0.19 oz). It has a straight black bill. The male has shining green upperparts with a bronzier green nape and rump. Its underparts are mostly glittering golden green. Its lower throat and upper breast are coppery bronze and the undertail coverts brownish. Its leg puffs are white. The tail is forked; its central feathers are blue-green and the outer two pairs dark green to blue-black. The female is slightly smaller and has somewhat greener undertail coverts but is otherwise similar to the male.
分类信息
The golden-breasted puffleg is monotypic. However, at one time it was suggested that the northern and southern populations formed subspecies.

分布与栖息地
The golden-breasted puffleg is found in the Central and Western Andes of Colombia with a few records in the Eastern Andes. It also occurs in much of the length of the Andes in Ecuador. The species inhabits the edges and clearings of stunted montane forest, elfin forest, and shrubby zones near treeline. In elevation in Colombia it ranges between 1,200 and 3,600 m (3,900 and 11,800 ft) but is usually found above 2,600 m (8,500 ft). In Ecuador it mostly occurs between 3,000 and 3,600 m (9,800 and 11,800 ft).

行为
The golden-breasted puffleg is suspected to make seasonal elevational movements but has not been documented doing so.<p>The golden-breasted puffleg forages for nectar at low flowers, both while hovering and by clinging to the flower. It is "active and aggressive" defending feeding territories. No details of its preferred plants are known. It also feeds on small insects like other hummingbirds.<p>Little is known about the golden-breasted puffleg's breeding phenology. A nest discovered in November in Colombia was a cup made of moss and sticks lined with plant down, placed on the end of a slender branch under a rock overhang. An adult was on the nest so the observer assumed that it was incubating eggs.<p>The golden-breasted puffleg's calls are "trit notes".

Yellow Rail
Coturnicops noveboracensis
Exceptionally secretive little rail. Overall the color of a perfectly toasted marshmallow; back pattern more complex with streaks of gold and black crossed by intricate white bars. Almost never seen in the open. When flushed, look for bold white patch on the inner flight feathers. Most similar to juvenile Sora; separable by back pattern and habits. If you're looking at a rail in the open, it's almost certainly not a Yellow Rail. Found in moderately wet marshes and meadows, where it finds cover among dense grasses. Most easily detected at night when it sings a distinctive song that sounds like two stones being tapped together: "tick-tick, tick-tick-tick", almost always in alternating sets of two and three notes, often confused with cricket frogs.
White-browed Antpitta
Hylopezus ochroleucus
Plump bird with a short tail and long legs. Unmistakable within its range. Has a brownish back, spotted breast, and rusty sides. Found hopping quietly on the ground or perching in the understory of deciduous wooded caatinga (dry scrubby forest). The song is a series of 12-14 notes, starting with four notes alternating in pitch, and finishing with descending whistles e.g. “piupiu-piupiu tetju tetju tetju tetjutu.”
Brown Honeyeater
Lichmera indistincta
Smallish honeyeater with a curved black bill. Grayish overall, with yellowish panels in the wings and tail, and a dark smudge around the eye. Also note bright yellow speckle behind the eye if seen well. In areas of overlap, juvenile Brown Honeyeaters are regularly confused with Dusky Honeyeaters (which are a darker sooty-brown and lack the yellow wing panel). Social and noisy, moving in active flocks. Found in a wide variety of habitats, including mangroves, forests, parks/gardens, and arid inland areas. Very vocal with a wide variety of chattering calls.
