Gorgeted Sunangel
Heliangelus strophianus
Unmistakable; glittering pinkish-purple throat is distinctive in good light, but also note the snowy white chest band, which is always obvious. Medium-sized with a rather short, straight bill. Like other sunangels, holds wings out for a few seconds after it lands. Based on plumage, could be confused with Purple-throated Woodstar, but the sunangel is larger with a much different flight style. The only sunangel within limited range on the west slope of Andes; occurs mostly in Ecuador, but barely extends into Colombia. Occurs in a rather narrow elevational band in the upper subtropical zone from around 1,700 to 2,300 m. Can be seen at all levels in the cloud forest, edges, and gardens, but most frequently at middle heights within the forest. Visits feeders.
识别特征
The gorgeted sunangel is 10 to 11 cm (3.9 to 4.3 in) long and weighs about 5.3 g (0.19 oz). Its bill is short, blackish, and straight. The species is sexually dimorphic, but only slightly. Both sexes are dark velvety green above with a small white postocular spot and a dark steel-blue tail. Their lower underparts are dark green with dark gray speckles towards the rear. The male has a small glittering green frontlet just above the bill. Its throat and upper breast gorget is glittering rose to violet and has a white pectoral band below it. The female's chin is dark gray-brown with white fringes on the feathers and occasionally some glittering rosy feathers. Juveniles are like the female but with a narrower white pectoral band.

分布与栖息地
The gorgeted sunangel is found from far southwestern Colombia's Nariño Department south discontinuously through much of western Ecuador. It primarily inhabits humid to wet premontane forest but is also found at the forest's shrubby borders and thickets. Within the forest it favors damp ravines. In elevation it ranges from 1,200 to 2,800 m (3,900 to 9,200 ft) but is rare at the upper elevations.

行为
Little is known about the gorgeted sunangel's movements but some seasonal altitudinal movement is likely.<p>The gorgeted sunangel is usually seen alone, so it is probably territorial. It feeds on nectar, mostly at low flowers but sometimes as high as the subcanopy. It stays in or near cover and shuns open areas. No further information has been documented, though other species of its genus include insects in their diets.<p>The gorgeted sunangel's breeding season is mainly between October and December but might begin earlier. The clutch of two white eggs is incubated by the female. Nothing else is known about the species' breeding phenology.<p>The gorgeted sunangel's song is "a repeated series of 2–3 high-pitched 'pseee' notes...followed by a slightly lower-pitched 'tsip' note." Its call is "a dry chattering followed by a mellow note 'kr..krr..krr..whee..'" and it also makes a high-pitched twitter.

Black-bellied Cicadabird
Edolisoma montanum
A medium-sized bird of montane forest canopy. Slate gray color with black wing and tail. Male has a black face whereas the female is more striking with all black underparts. Female is distinctive, but male is similar to Common, Papuan and Gray-headed Cicadabird males but has more black on the wing. Song, a duet. The male gives a downslurred, nasal “wiiiuuuuuu!” and female joins in with 3-4 harsh rasping notes “rak-rak-rak!”.
Rufous Hornbill
Buceros hydrocorax
A large hornbill of lowland and foothill forest. Body dark, with rufous thighs, chest, and neck, a whitish tail, a red casque, a long red bill, and a black face bordered behind with yellow. Females have a smaller casque, a paler eye, and no eye-ring. Southern birds have a yellow-tipped bill. Similar to the Writhed Hornbill, but Rufous lacks the black tip to the tail and has a rufous rather than black or pale head. Voice includes loud, downslurred nasal honking notes.
Calandra Lark
Melanocorypha calandra
Large lark with a strong, thick bill and an obvious pale eyebrow. Thick black patches at the neck sides can vary with posture and between individuals. In flight, dark underwings with white trailing edge to upperwings are diagnostic. "Slow-motion" wingbeats in song flight make it look bigger than it is. An inhabitant of open farmland and natural steppe. May form large flocks in winter. Jumbled song consists of trills and chips, and frequently mimics other species.
