Bare-faced Ground Dove
Metriopelia ceciliae
Attractive but easily overlooked small dove of the Andes. Fairly common on rocky and scrubby slopes around towns and villages in agricultural areas. Usually in pairs or flocks, sometimes mixed with other seed-eating birds. Feeds on ground, but perches on walls and prominent rocks; often not seen until flushed from close range, when flies up with a loud rattling wing whistle. Pale-dappled wing coverts and big orange eyering are diagnostic.
识别特征
The bare-faced ground dove is 16 to 17 cm (6.3 to 6.7 in) long and weighs about 66 g (2.3 oz). The nominate subspecies is brown or grayish brown above, with white or buffy tips on feathers giving a spotted appearance. Its neck and breast are gray with a reddish or pinkish tinge and its belly is buffy. The outer tail feathers are black with white tips. The eye is blue or bluish white surrounded by bare yellow to orange skin that is itself surrounded by narrow black feathers. Male and female plumages are essentially alike though the female's breast is less pink. Juveniles are similar to the adults. M. c. obsoleta is paler and grayer than the nominate, and M. c. zimmeri is darker, browner, and has a yellow to blue eye.
分类信息
The bare-faced ground dove and its sister species Moreno's ground dove (Metriopelia morenoi) were previously placed in genus Gymnopelia. Three subspecies are recognized, the nominate Metropelia ceciliae ceciliae, M. c. obsoleta, and M. c. zimmeri. However, the Cornell Lab of Ornithology's Birds of the World considers M. c. obsoleta to be "doubtfully valid".

分布与栖息地
The nominate subspecies of bare-faced ground dove is fond in western Peru, M. c. obsoleta in northern Peru, and M. c. zimmeri in southern Peru, western Bolivia, northern Chile, and northwestern Argentina. They inhabit arid and semi-arid landscapes of sandy soil with little vegetation. In higher elevation areas it frequents human habitations, apparently because the surrounding countryside is treeless, and it is also common in major urban areas such as Lima. In elevation it generally ranges between 2,000 and 4,500 m (6,600 and 14,800 ft) but is found much lower in western Peru.

The bare-faced ground dove is known to feed on the ground, usually in small groups, but its diet has not been documented.<p>The bare-faced ground dove nests on the ground, on cliffs, or in holes in buildings. Essentially nothing else is known about its breeding phenology.<p>Though the bare-faced ground dove's vocalizations are not well known, it "has been recorded producing a series of five similar ascending and later abruptly descending double-sounding cooing notes" and a "Wo ow" sound "like a growling wow".

Tricolored Munia
Lonchura malacca
Small, finchlike bird of weedy and grassy areas in tropical lowlands. Often in small flocks, which associate readily with seedeaters and grassquits. Adult is handsome and striking with rusty upperparts. Black head and underparts are cut by a broad white swath from flanks across the lower breast. Note stout gray bill. Juvenile notably plain, buffy brown overall with stout bluish-gray bill. Note the pointed tail, unlike seedeaters and grassquits. Native to Asia and spreading in New World as an escaped cage bird.
Lilian's Lovebird
Agapornis lilianae
A gregarious small green parrot with a red bill, white eye-ring and orange-red face. Immature has a duller bill and eye-ring. Pairs and small and large flocks inhabit tall broadleaf Mopane and thorn tree woodland, where they can be locally common. Gives a variety of chittering and screechy chatters, drawing attention to their presence. The similar Black-cheeked Lovebird is localized and endemic to southwest Zambia; it differs from Lilian’s Lovebird by its chocolate brown face.
Yapacana Antbird
Aprositornis disjuncta
Odd, slender antbird with a rather long bill. Males are gray above and white below with white spots on the wings; females have rusty underparts and lack wing spots. Found across a restricted range in the understory of stunted campina forests. Does not generally associate with mixed-species flocks, but may sometimes attend army-ant swarms. The song is a series of harsh notes with short “pips” in between: “grrrrrrr-pipip-grrrrrrrr-pip.”
