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.

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".

Ashy-crowned Sparrow-Lark
Eremopterix griseus
A small, stocky bird with a heavy, finch-like bill. Males have a gray head that contrasts with a black eye-stripe, and black on the collar, throat, and underparts. Females are pale brown with weak streaks on the head, back, and underparts. Similar to Black-crowned Sparrow-Lark, but Ashy-crowned males are told apart by the gray on the head. Females are difficult to distinguish. Inhabits dry scrub, fields, and rocky country. The song is often given in display flight, and consists of monotone whistles interspersed with buzzy notes.
Comoro Scops-Owl
Otus pauliani
Small compact owl with very small ear tufts that are often invisible. Rufous-brown on the underparts and dark brown on the back. Found in montane forest and along forest edge on the island of Grand Comoro. Fairly shy and wary. The vocalization is a quiet, repeated “pru” that is given at a rate of about two notes per second, sometimes for many minutes at a stretch. Easily identified, as the only other owl on Grand Comoro is the much larger Barn Owl.
Orange-banded Thrush
Geokichla peronii
An unmistakable thrush with a “tiger-striped” face pattern, a white throat, a broad orange chest band, orange flanks, a white belly, and extensive bold white wing markings. Juveniles show rusty wing spots, pale streaking, a black and buff breast band, and black flank spots. Forages singly or in pairs on the ground and in trees, in forests and wooded patches within lowlands and hills. Confined to the eastern Lesser Sundas. Gives a rich, musical song characteristic of thrushes, with sequences of fluty upslurred and downslurred whistled notes comprising repeated phrases mixed with softer, chuckling sounds and thin, high-pitched notes.
