Buff-winged Starfrontlet
Coeligena lutetiae
Large, long billed hummingbird of the high Andes from Colombia south to far northwestern Peru. Mostly green with obvious buffy wing patch, which is its best ID feature; male has a purple spot on throat, and female has a buffy throat. Found in cloud forest and elfin forest up to near tree line; typically seen in clearings and forest edge, and visits feeders in some areas.
识别特征
The buff-winged starfrontlet is about 14 cm (5.5 in) long. Males weigh 6.9 to 7.2 g (0.24 to 0.25 oz) and females about 6.6 g (0.23 oz). Both sexes have a long, black, slightly upturned bill and a white spot behind the eye. Both sexes have a forked tail though the female's is not as deeply indented as the male's. Males of the nominate subspecies has velvety black upperparts with a glittering green forehead. They have a violet gorget and the rest of the underparts are dark green. The wings are dark with a large cinnamon-buff patch and the tail is bronzy black. Nominate females have shining dark green upperparts. Their throat is cinnamon-buff and the rest of the underparts golden green with pale fringes on the feathers. They have the same cinnamon-buff wing patch as the males but the tail is bronzy green.<p>Males of subspecies C. l. albimaculata have almost white wing patches but are otherwise like the nominate. Females have a paler throat than the nominate and a cinnamon tinge to the underparts, whose golden green is also less iridescent.
分类信息
The buff-winged starfrontlet and most other members of genus Coeligena were at one time placed in genus Helianthea but have been in their current placement since the mid-1900s. The International Ornithological Committee (IOC) and BirdLife International's Handbook of the Birds of the World (HBW) recognize two subspecies, the nominate C. l. lutetiae and C. l. albimaculata. However, the Clements taxonomy treats the species as monotypic.

分布与栖息地
The nominate subspecies of buff-winged starfrontlet is found from the Central Andes of Colombia south through the Andes of Ecuador into far northern Peru. C. l. albimaculata is found only in northwestern Ecuador. The species inhabits cloudforest, elfin forest, and the lower edges of páramo. In elevation it ranges from 2,600 to 4,800 m (8,500 to 15,700 ft) but is most common around 3,000 m (9,800 ft).

行为
The buff-winged starfrontlet is generally sedentary, though some movement to follow flowering plants has been noted.<p>The buff-winged starfrontlet feeds on nectar by trap-lining, visiting a circuit of flowering plants, but it also will defend patches of flowers. It most often forages at low levels at the margins of forest, and often clings to flowers to feed as well as hovering. In addition to feeding on nectar it captures small arthropods by gleaning from foliage and by hawking.<p>The buff-winged starfrontlet's breeding season in Colombia is August and September; it is not defined elsewhere. It builds a cup nest in a branch fork, typically about 2 to 4 m (7 to 13 ft) above ground. The female incubates the clutch of two eggs for 15 to 17 days; the time to fledging has not been determined.<p>The buff-winged starfrontlet makes a "thin, wiry chatter with rattles", often during territorial disputes. While feeding it often repeats "a characteristic, nasal 'unk'".

Moluccan Eclectus
Eclectus roratus
Robust, big-headed, and rather short-tailed parrot endemic to the Moluccas, where it inhabits lowland and foothill forests. Male bright green with red underwings and orange bill, female bright red with violet belly and dark bill. Usually seen flying above forests at first light, squawking loudly. Calls include an ear-shattering, high-pitched squawk, as well as a lower, crow-like caw. Formerly grouped with other closely related species under “Eclectus Parrot.”
Cedar Waxwing
Bombycilla cedrorum
Plump, smooth-plumaged bird with distinctive thin, high-pitched call. Adults have a sleek crest, black mask, pale yellow wash on the belly, and yellow-tipped tail. Juveniles are drabber than adults, with coarse streaking on the breast and a reduced mask. Widespread and fairly common in open woodlands, orchards, and shrubby areas throughout most of North America. Winter range is variable and somewhat dependent on fruit crops; sometimes ventures as far south as Panama. Often gathers in large flocks, especially around fruiting trees. Compare with Bohemian Waxwing in the northern part of range; Cedar is smaller, browner, and has a white (not rufous) undertail.
Rhinoceros Hornbill
Buceros rhinoceros
Majestic and stately inhabitant of mature lowland and foothill forests. Pitch black with a white tail marked by a single dark bar. Enormous bill is bright orange with a prominent casque that is short and rectangular in females, long and upswept in males. Often seen in powerful flight over forests, typically in pairs or small groups. Gives low, resonant calls, usually in series: either a single-syllabled “rohh” or a disyllabic “roh-ow.”
