Green Inca
Coeligena conradii
Flashy green and white hummingbird of Andean cloud forest. It is nearly endemic to Venezuela, but also reaches into Colombia near the border. Rather large and long-billed with a bold, white breast patch. White tail markings really stand out when it flares its tail. Male’s upper throat is green, and female’s is pale buff. Often seen feeding on red, tubular flowers and sometimes visits feeders. Formerly considered a subspecies of Collared Inca.
识别特征
The green inca is about 14.5 cm (5.7 in) long; one female specimen weighed 6.7 g (0.24 oz). Adult males are mostly grass green, with a wide white collar across the upper breast. Their outer tail feathers are mostly white with green tips and their wings are brownish. Females are also mostly grass green above but with a smaller white collar and a rusty throat with green spots. The rest of their underparts are grayish with green mottling and spots.
分类信息
The International Ornithological Committee (IOC), the Clements taxonomy, and BirdLife International's Handbook of the Birds of the World (HBW) recognize the green inca as a species. The South American Classification Committee of the American Ornithological Society treats it as a subspecies of the collared inca (C. torquata) but is seeking a proposal to recognize it as a species.

分布与栖息地
The green inca is found in the Andes of northwestern Venezuela between the states of Trujillo and Táchira and in northern Colombia's Norte de Santander Department. It inhabits the interior and edges of humid montane cloudforest. In elevation it mostly ranges between 1,800 and 3,000 m (5,900 and 9,800 ft) but can be found as low as 1,500 m (4,900 ft).

行为
As far as is known, the green inca is a year-round resident throughout its range.<p>The green inca forages by trap-lining, visiting a circuit of flowering plants. It mostly feeds from the understory to the forest's mid-level but also sometimes in the canopy. It feeds on nectar from Cavendishia, Fuchsia, plants of family Ericaceae, and others such as vines. It also catches insects by hawking from a perch or by gleaning while hovering.<p>Nothing is known about the green inca's breeding biology.<p>The green inca's most common vocalization is "a squeaky chatter". It also makes "a soft, low, reedy whistle "tu-tee", "a longer series...pip..pip..pip...", "a repeated phrase such as tsi-tsi-tsiririt...tsi-tsi-tsiririt...", and while foraging a "short spit or tsit".

Cuban Tody
Todus multicolor
A small, gemlike, woodland species that is usually found in pairs. The rather large head, long bill, and short tail create a unique profile. Also note its shimmering green upperparts and red throat and sides. No similar species occur within its range. It usually hunts from low-to-middle level perches, sitting nearly still before leaping upwards to snatch prey from twigs and leaves. Vocalizations include a loud “chuk, chuk, chuk, chuk,” uttered at a rate of about seven to ten notes per second, with each burst consisting of one to ten notes; bursts often come in rapid succession.
White-sided Hillstar
Oreotrochilus leucopleurus
Small hummingbird of the Andes from southern Bolivia through Argentina into central Chile; found in rocky and shrubby valleys, villages, and any open or semiopen areas with flowers. Often builds nest under eaves of buildings or bridges: a bulky cup of plant material and wool to insulate against cold nights. Fairly common. Readily identified in most of range by extensively white tail. Male has an emerald green gorget and a broad blue-black stripe on belly. Female is rather drab, but note slightly decurved bill, spotted throat, and tail pattern.
Little Tern
Sternula albifrons
Tiny, delicate-looking tern. Mainly coastal, but also occurs inland locally. Breeding plumage has black cap with white forehead chevron, black-tipped yellow bill. Readily identified by tiny size, though wintering adults can be confusingly similar in patterning to Common Tern; look out for black stripes extending from the shoulder to the wingtip. Breeds colonially on sandy and stony substrates, at times with other terns, from beaches to riverbanks and lakeshores. Often overlooked unless noisy and mobbing you at a colony. Flies with hurried deep wingbeats; splash dives in water to catch small fish.
