Rusty-barred Owl
Strix hylophila
Uniform buffy-brown owl with dark eyes. Mottled brown and white above and lightly barred on the breast. Found in montane, lowland humid and second growth, preferring areas with dense understory. Both sexes give a high-pitched meow and low harsh “grugrugru, grugrugru.”
识别特征
The rusty-barred owl is about 35 cm (14 in) long. Males weigh 250 to 340 g (8.8 to 12 oz) and females 275 to 395 g (9.7 to 14 oz). The species has light rusty brown facial discs with concentric darker brown rings and small white "eyebrows". Adults' upperparts have white, brown, and orange-buff barring. The chest and flanks are orangish buff and the belly is whiter; both areas have dark brown bars. The legs are feathered. The eyes are dark brown, the bill yellowish horn, and the toes yellowish gray. Juveniles are overall buff with faint darker barring.
分类信息
The rusty-barred owl is one of seven members of genus Strix found in South America, according to the International Ornithological Committee (IOC). It appears to be most closely related to the Chaco owl (S. chacoensis) and rufous-legged owl (S. rufipes). All three have vocalizations that are very different from those of other Strix owls and genetic studies may find that they belong in their own genus. The rusty-barred owl is monotypic.

分布与栖息地
The rusty-barred owl is found in southeastern Brazil from Minas Gerais to Rio Grande do Sul, in southeastern Paraguay, and in Argentina's extreme northeastern Misiones Province. It inhabits the interior and edges of a variety of wooded landscapes including montane, tropical evergreen, and temperate forest; secondary forest; and pine platations. It can be found close to human habitation. In elevation it ranges from sea level to at least 1,000 m (3,300 ft).

Western Plantain-eater
Crinifer piscator
Unusual gray turaco with a long tail and bushy crest. White bars in the outer wing are conspicuous in floppy flight. Found in savanna, woodland, shrubby cultivation, and gardens. Usually in small groups. Loud and vocal. The call is a series of yelps that accelerate and become louder, usually given in a wild duet or chorus. Very similar to Eastern Plantain-eater, but there is very little overlap in range; Western can be distinguished by the lack of white in the tail and the black-spotted rather than barred back.
Blue-backed Parrot
Tanygnathus everetti
A bright green parrot with a large bill that is orange in males and horn-colored in females and juveniles. Endemic to lowland and foothill forests in the Philippines; now rare and localized due to habitat loss and trapping. Differs from Blue-naped Parrot in the absence of a pale tail tip and yellow underwings. Vocal, giving a loud nasal high-pitched “klee-oo” as well as “kew” and explosive “kyow” calls in flight. Often active and vocal at night.
Dusky Nightjar
Antrostomus saturatus
Small dark nightjar with very limited range in the highlands of Costa Rica and Panama. Few obvious plumage features: entire body is intricately patterned with dark brown, black, and buff. Pale corners to tail (white in male, buffy in female). Fairly common above around 1,500 m, where it can be found at the edge of cloud forest. Usually perches on a fence post or low branch. Strictly nocturnal, and easily detected by voice; listen for the trilled “whip, wee-per-wee!,” rising at the end. Closely related to whip-poor-wills further north.
