Rose-headed Parakeet
Pyrrhura rhodocephala
Green parakeet with a long red tail, prominent white patch in wings, white eyering, and red ear patch and crown. Mostly seen in large flocks flying, eating fruits, or perching quietly in trees. Common in cloud forests and forest edges. Voice similar to related species. Similar in flight to Red-eared Parakeet but shows white wing patch and red crown, and almost no range overlap. Endemic to the Andes of Venezuela.
识别特征
The rose-crowned parakeet is a small parrot, measuring 24 cm long with a wing length of 13 to 14.2 cm, tail 9.7 to 11.5 cm, and bill 1.6 to 1.8 cm long, with a tarsus length of 1.4 to 1.6 cm. As an adult it is mainly green; its bright red cap and white primary coverts (blue in juveniles) help to distinguish it from all other long-tailed, small parrot species in South America. It has blue primaries and a red tail and the sexes are alike. No other members of the genus Pyrrhura occur in its range. The painted parakeet also has red on its head but has bold, scaly patterns on its breast and throat. The bare skin around the eye is white.
分类信息

分布与栖息地
It is endemic to Venezuela, found only in the Andes of the north-west in the Cordillera de Mérida, from Táchira to Trujillo. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest, at elevations of 800 m to 3,100 m asl, but mostly at 1,500–2,500 m. It can also be found in farmland with scattered trees and at the forest edge.<p>Its estimated extent of occurrence is 17,000 km2. In 1988 it was assessed for the IUCN Red List as Near Threatened, updated to Lower Risk in 2000 and Least Concern since 2004; in 2002 it was described as "fairly common." A reported population decline caused by deforestation had not become problematic as of 2010, but Parr and Juniper considered that in a species with such a small range this must present a long-term threat. The current population trend is "stable" although the number of mature individuals is unknown. The rose-crowned parakeet is on the CITES Appendix II which "includes species not necessarily threatened with extinction, but in which trade must be controlled in order to avoid utilization incompatible with their survival."

行为
The rose-crowned parakeet is gregarious, forming noisy flocks of 10–30 birds when not breeding, and gathers in larger numbers to roost. It makes movements each day, but the species is probably resident. The voice is described as "harsh [and] reedy", though “apparently quieter than other Pyrrhura conures." The flight is "swift and direct.” Nothing is known of the species' diet, though it is suspected to eat berries, seeds, fruits and flowers. It is thought to breed in April, May and June, probably laying 4–6 eggs.

Cape Robin-Chat
Dessonornis caffer
Pretty robin-chat with a short white eyebrow and a rufous chest. This is the only robin-chat with a gray belly. The outer tail feathers are orange, which can be conspicuous in flight. Found in many different habitats, including fynbos, scrub, heath, gardens, forest edge, and thicket. More fond of open habitats than other robin-chats. Away from South Africa, only found in the mountains. Song is a typical thrush-like series of inquisitive, cheerful notes.
Rufous-tailed Tyrant
Knipolegus poecilurus
Medium-sized flycatcher found in the Andes from Venezuela to Peru as well as the tepuis of Venezuela and Brazil. Grayish-brown overall with a distinctive red eye, pale tawny belly, and tawny or grayish wingbars. Sexes similar. Found at the edge of montane forest from around 900–2,200 m. Usually perches conspicuously.
Hooded Yellowthroat
Geothlypis nelsoni
Rather local and endemic to highlands of Mexico. Unlike most yellowthroats, not found in marshes. Occurs in brushy scrub and chaparral thickets, where usually quite skulking, but sometimes sings from conspicuous perches. Upperparts and flanks are relatively dark greenish olive. Duskier than Common Yellowthroat, which is a common migrant throughout range of Hooded, but Common are usually near water. Male Hooded has gray border above black mask. Female has a ghosting of male pattern with some grayish on forehead, but can be difficult to distinguish from Common.
