Rusty-fronted Canastero
Asthenes ottonis
Small, long-tailed bird of high-elevation scrub. Light brown, with reddish wings and tail and small reddish patches on the throat and forehead. Prefers dense shrubby areas, including Polylepis woodland, where it forages secretively within bushes. Its small size, lack of strong streaking, and long, reddish tail distinguish it from similar species within its range. Listen for its energetic song, an accelerating series of high, harsh notes.
识别特征
The rusty-fronted canastero is 18 to 19 cm (7.1 to 7.5 in) long and weighs about 13 g (0.46 oz). The sexes have the same plumage. Adults have a grayish buff supercilium and arc below the eye, a small dark line in front of the eye, and a dark brownish patch behind the eye on an otherwise dull brownish face with pale streaks. Their forehead ("front") is rufous with faint pale streaks. Their crown, back, and rump are rich brown and their uppertail coverts chestnut-rufous. Their wings are mostly rufous-chestnut with dark fuscous tips on the flight feathers. Their tail is rufous-chestnut; the inner three pairs of feathers are longer than the others and have dark fuscous shafts. Their chin and upper throat are light orange-rufous to chestnut-rufous, their lower throat pale grayish buff streaked with brownish gray, their breast slightly darker and streaked with pale buff, their belly buff-whitish, and their flanks and undertail coverts rufescent brown. Their iris is dark brown to brown, their maxilla dark horn to blackish, their mandible silvery to dark horn with a dark tip, and their legs and feet olive-gray to dark gray.
分类信息
The rusty-fronted canastero is monotypic. At times it has variously been treated as a subspecies of the canyon canastero (A. pudibunda) and as a superspecies with it and the maquis canastero (A. heterura), but genetic data show it to be most closely related to the eye-ringed thistletail (A. palpebralis).

Common Pauraque
Nyctidromus albicollis
Cryptically patterned nightbird; widespread and common in Central and South America, limited U.S. range. Found in shrubby woodlands. Patterned with gray, gold, and brown; note especially cinnamon cheeks and golden edges on back and wing feathers. In flight, note white outer tail feathers and white bar across the wings. Roosts on the ground during the day; actively hunts for insects at night. Song is a distinctive, rich, slightly buzzy "pur-WEEooo." Relatively long tail compared with other similar nightbirds.
Taita Fiscal
Lanius dorsalis
A small black, white, and gray shrike. The sexes are similar, but females can show a small chestnut patch on the flanks. Note the small white mark in the wing and the white outer tail, which can be conspicuous in flight. Found in dry savanna and grassland. Perches up conspicuously, often in pairs. Very similar to Somali Fiscal, but has only a single white patch at the center of the wing. The repetitive vocalizations include rasping and liquid notes, often delivered in a rising pattern.
Spotted Owl
Strix occidentalis
Medium-sized owl typically found in mountainous regions with mixed conifers and oaks. Overall brown with bold white spots on belly and back. Black eyes, unlike most other owls; main confusion species is Barred Owl. Spotted is well-named, with much more obvious spots on chest and belly than Barred Owl, and lacks distinct vertical stripes. Also note voice: one hoot, followed by a pair of hoots, followed by a final single hoot. Two separate populations: birds along the Pacific coast and the Sierra Nevada average darker, richer brown than birds further south and inland.
