Golden-winged Parakeet
Brotogeris chrysoptera
In flight, note compact shape, pointed tail, and bounding flight with jerky wingbeats. Yellow wing patch can be hard to see when perched, but note small size, stocky proportions, mostly green plumage,and pale bill. Found in lowland rainforest; usually flying high above the forest canopy. Feeds in the canopy on flowers and fruit. Distinctive grating call is almost always heard before these birds are seen.
识别特征
The golden-winged parakeet is about 16 cm (6.3 in) long and weighs 47 to 80 g (1.7 to 2.8 oz). The species is almost entirely green. Adults of the nominate subspecies have a browish frontal band above the bill, and orange-brown spot on the chin, and bright orange primary coverts. Subspecies B. c. tuipara has an orange frontal band and chin and yellow edges on the outer tail feathers. B. c. chrysosema has a yellowish orange frontal band and yellow primary coverts. B. c. solimoensis is like chrysosema but with a paler frontal band. B. c. tenuifrons has yellow edges on the outer tail feathers like tuipara but no frontal band. Immature birds have entirely green wings.
分类信息
The golden-winged parakeet was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus chrysopterus. Linnaeus based his description on the "golden-winged parakeet" that had been described and illustrated in 1760 by the English naturalist George Edwards in the second volume of his Gleanings of Natural History. Edwards was uncertain about the origin of his specimen. Linnaeus specified the type location as "India". It was redesignated as "Guiana" in 1912. The golden-winged parakeet is now one of eight species placed in the genus Brotogeris that was introduced in 1925 by Irish zoologist Nicholas Aylward Vigors. The genus name is from the Ancient Greek brotogērus meaning "with human voice". The specific epithet chrysoptera is from the Ancient Greek khrusopteros meaning "golden-winged" (from khrusos "gold" and pteron "wing").<p>Five subspecies of golden-winged parakeet are recognized:<p>B. c. solimoensis has sometimes been included in the nominate B. c. chrysoptera. Subspecies B. c. tuipara and B. c. chrysosema have sometimes been treated as separate species. The golden-winged and cobalt-winged parakeet (B. cyanoptera) are sister species.

分布与栖息地
The subspecies of the golden-winged parakeet are found thus:<p>In most of its range the golden-winged parakeet inhabits undisturbed lowland rainforest, secondary forest, savanna, coastal woodlands, and towns (as long as there are tall trees). North of the Orinoco River in Venezuela it inhabits cloudforest as high as 1,200 m (3,900 ft).

行为
The golden-winged parakeet is mostly sedentary but there are suggestions of some irregular wandering.<p>The golden-winged parakeet feeds mostly on flowers and their nectar; a wide variety of plant families provide them. It also feeds on seeds, berries, palm fruits, and insects and snails in still water.<p>The golden-winged parakeet's nesting season varies geographically; it nests somewhere in almost any month. It nests in a cavity, natural or excavated, in a tree or arboreal termite nest. The clutch size is three or four eggs. The incubation period, time to fledging, and details of parental care are not known.<p>The golden-winged parakeet's common calls are "a high-pitched “klee”, shrill “chree” or bisyllabic “chree-chree”" that are given both from a perch and in flight. It also makes "a fast chattering series “cra-cra-cra-cra-cra”." Members of flocks in flight often call simultaneously, making a cacophony.

California Condor
Gymnogyps californianus
This behemoth is unmistakable solely due to its massive size, much larger than any other raptor or vulture. Adults are black with a white stripe on the underwing and an orange head. Wingtips are splayed into conspicuous fingertips. Young birds are duller with a gray head and only slightly paler stripe on the underwing. Found in very small numbers in coastal hills and mountains of California and around the Grand Canyon. Usually seen soaring singly or in pairs. Critically endangered; only recently has this species started breeding successfully again in the wild.
Gorgeted Wood-Quail
Odontophorus strophium
Scarce quail restricted to cloud forest in the northern half of Colombia’s eastern Andes. Adult has distinctive black and white crescents on the throat, which may be reduced or lacking in young birds. Male has chestnut underparts and white spots on the breast; female has gray underparts. Shy and not often seen, but with luck it may be encountered in small groups that walk on the forest floor. Song is like that of other wood-quails, a long and rollicking series of whistles.
Singing Quail
Dactylortyx thoracicus
Small, retiring quail of forest understory. Rarely seen, but can be located by listening for noisy rustling in the leaf litter as birds scratch like chickens. Prefers to run away rather than flush. Loud song often reveals its presence, given mainly early and late in the day: first few notes similar to Little Tinamou song, but then breaks into rollicking choruses that can be almost deafening if close by. Male has rusty face and gray body, female colors reversed, with gray face and rusty body.
