Hoary Puffleg
Haplophaedia lugens
Dull hummingbird restricted to mid-elevation Andean cloud forest in northwestern Ecuador and western Colombia. Mostly green, but underparts are grayer with white scaling; also note coppery tinge to crown and rump. White leg puffs are usually conspicuous on male, but they are much smaller on female and immature and can be concealed behind belly feathers. Scarce; usually encountered feeding low inside forest, often near streams.
识别特征
The hoary puffleg is 9 to 10 cm (3.5 to 3.9 in) long and weighs 5 to 6 g (0.18 to 0.21 oz). It has a straight black bill. Males have bronze-green upperparts with a coppery hue on the crown and rump. The underparts are dark gray with a whitish scaly appearance on the throat and breast and a greenish sheen on the flanks. The leg puffs are white on the outside and chestnut on the inside. The slightly forked tail is blackish. Females are similar but duller overall and their leg puffs are entirely white. Juveniles resemble females.

分布与栖息地
The hoary puffleg is found in a fairly narrow band on the Pacific slope of the Andes, from southwestern Colombia's Nariño Department south into Ecuador as far as Pichincha Province. It inhabits cloudforest, the borders of other types of tropical and subtropical forest, and scrublands. It tends to stay in low dense vegetation, often near streams. In Colombia it has been recorded between elevations of 1,200 and 2,000 m (3,900 and 6,600 ft) and locally as high as 2,500 m (8,200 ft). In Ecuador records span from 1,525 to 2,100 m (5,000 to 6,900 ft).

行为
The hoary puffleg is a year-round resident throughout its range.<p>The hoary puffleg forages for nectar mostly near the ground but occasionally in the canopy. It is territorial and defends clusters of flowers. It typically feeds on flowers with short corollas such as Besleria sp., Palicourea sp., Thibaudia sp., Melastomataceae, and Marantaceae. In addition to nectar, it feeds on insects that it gleans from leaves.<p>The hoary puffleg's breeding season has not been well defined, but nesting has been recorded in May and August. The nest is a hanging cup or ball made of moss and spiderweb; it is attached to the underside of a fern or other large leaf that protects it from rain. It is typically 0.5 to 2 m (2 to 7 ft) above the ground. The female incubates the clutch of two white eggs for 15 to 17 days and fledging occurs 20 to 24 days after hatch.<p>Only one hoary puffleg vocalization has been described, "a single strident 'tzik' or doubled 'tsi-tsik', repeated at irregular intervals". It is given both from a perch and in flight.

Hill Swallow
Hirundo domicola
A small dark blue-black swallow with rufous-chestnut on its face and a short tail. Except for a black triangular eye-stripe extending to the bill, the entire forehead, chin, throat, and upper breast are rufous-chestnut, without any dark necklace like that of Barn Swallow, the main confusion species. Hill Swallow’s dark upperparts have a blue-green sheen that is only visible when seen up close, while the underparts are dingy white with ashy-gray on the flanks. Juveniles have duller chestnut on the face. Mainly inhabits open areas such as grasslands, reservoirs, and tea estates in the high hills above 500 meters of elevation; very rare at lower elevations. Often seen wheeling and looping in the air after insects, with a swift flight action reminiscent of a Barn Swallow with a shorter tail.
Black-headed Saltator
Saltator atriceps
Fairly common in humid tropical lowlands. Favors forest edge, plantations, adjacent semi-open areas with trees and hedges. Usually in noisy small groups moving at mid-upper levels. Black head and bib surrounds white throat patch (throat patch buffy in Los Tuxtlas region of southern Veracruz), upperparts bright golden green. Larger and noisier than the rather similar Buff-throated Saltator, which has a less contrasting black head.
Rufous-lored Tyrannulet
Phylloscartes flaviventris
Distinctive small tyrannulet with rufous brow, black mask, olive back, and yellow underparts. Looks like a more colorful version of Rufous-browed Tyrannulet. Sexes similar. Found alone or in pairs, often in mixed-species flocks, in the canopy of forest. Occurs in humid forest and forest edges of montane regions. The typical voice has four high notes “teeup teeup teeup teeup.” No similar species in range. Endemic to the Coastal Cordillera of Venezuela.
