Brown-rumped Foliage-gleaner
Automolus melanopezus
Subtly-patterned foliage-gleaner. Warm dark brown overall, lighter below, with an orange-brown throat patch, and red eye. Found mostly in bamboo forests, as well as occasionally in areas of dense understory within mature rainforest, like vine tangles and in vegetation in upland ravines. Listen for its unique song, consisting of two or three liquid “wheep” notes followed by a chuckling trill accelerating into a rapid “trrrr.”
识别特征
The brown-rumped foliage-gleaner is 16 to 19 cm (6.3 to 7.5 in) long and weighs 27 to 32 g (0.95 to 1.1 oz). It is one of the smaller members of its genus and has a shortish and heavy bill. The sexes have the same plumage. Adults have a mostly rich dark brown face with a few buff streaks on the ear coverts, grizzled brownish and grayish lores, and an ochraceous malar area. Their crown is rich brown with some faint pale spots on the forehead. Their back and rump are rich brown that blends to chestnut-tinged brown uppertail coverts. Their wing has dull ochraceous at the bend, dark reddish brown coverts, and somewhat more rufescent flight feathers. Their tail is dull reddish brown. Their throat is dull tawny-buff that becomes light brown on the breast and belly. Their sides and flanks are darker brown and their undertail coverts pale rufescent brown. Their iris is dark red to orange, their maxilla dark grayish to blackish, their mandible pale gray to grayish brown, and their legs and feet olive-gray to greenish gray. Juveniles have thin dark edges on their crown feathers and a paler throat and darker and browner underparts than adults.

分布与栖息地
The brown-rumped foliage-gleaner has a disjunct distribution in the western Amazon Basin. One population is found around where southwestern Colombia, eastern Ecuador, and northern Peru meet. The other is found in a band in southeastern Peru, northern Bolivia, and west-central Brazil. Despite this separation, the populations are essentially phenotypically identical. The species inhabits tropical evergreen forest, usually on floodplains (both várzea and terra firme), and almost always in or near thickets of Guadua bamboo. In elevation it mostly ranges between 300 and 500 m (1,000 and 1,600 ft) and locally occurs up to 600 m (2,000 ft).

其他鸟类
Crested Doradito
Pseudocolopteryx sclateri
A small flycatcher with bright yellow underparts, a shaggy crest, and three wingbars. Inhabits marshes and flooded grasslands with overgrown vegetation. The song is a very soft and squeaky series of “tsik-tsik-tsee-lee” notes. Other doraditos have no wing marks.
Grayish Eagle-Owl
Bubo cinerascens
A fairly large gray owl with small ear tufts. The eyes are dark brown. Found in a variety of woodland and savanna habitats, often around cliffs and other rocky areas. Frequently in pairs. Very similar to Spotted Eagle-Owl, but there is little range overlap, and Grayish is easily separated by its dark eyes. The call is a single short “hoooo.”
European Bee-eater
Merops apiaster
Spectacularly colorful and unmistakable long-billed insect-eater with a bright yellow throat, gemstone-blue belly, and flame-colored back. Found in open and semiopen country, mainly in drier areas; nests colonially in burrows dug into sand banks, often river banks. Usually seen perched on wires or circling in swallowlike flight, often in small groups; feeds by catching insects (especially bees) on the wing. Quite vocal, often giving distinctive pipping calls.
