Rufous-necked Foliage-gleaner
Syndactyla ruficollis
Relatively brightly-colored foliage-gleaner restricted to mountains and hills of southwestern Ecuador and northwestern Peru. It has an orange nape and sides of neck, a cinnamon tail, buffy eyebrow and throat, and buffy streaks on the underparts. Sexes look alike. Found in both dry and humid forest, including areas with abundant bamboo, and typically seen at lower to middle levels. Song is a harsh, scratchy “bouncing ball” series. Threatened by habitat loss.
识别特征
The rufous-necked foliage-gleaner is 18 to 19 cm (7.1 to 7.5 in) long and weighs 29 to 39 g (1.0 to 1.4 oz). It is a largish furnariid with a less wedge-shaped bill than others of its genus. The sexes have the same plumage. Adults have an orange-rufous supercilium that extends to the nape; a dark brownish band behind the eye; grizzled grayish, dark brownish, and buff lores and ear coverts; and an orange-rufous to ochraceous buff area below the eye. Their crown is dark rufescent brown and they have an ill-defined collar of rufous streaks and spots. Their back is rich rusty brown with long thin buff streaks, their rump a redder brown, and their uppertail coverts bright chestnut. Their tail is dark chestnut and their wings are rich rusty brown with slightly darker primary coverts. Their chin is pale tawny-ochraceous, their throat more intensely ochracous, their breast olivaceous-brown with blurry rufescent buff streaks, their belly medium olivaceous brown, their flanks a slightly darker brown with a rufescent tinge, and their undertail coverts dark rufous. Their iris is brown, their maxilla dark brown to blackish, their mandible pale brownish or pale grayish, and their legs and feet grayish olive or olive-greenish. Juveniles are generally duller overall than adults, with a duskier (less brownish) crown and some dark brown edges on the throat feathers.

分布与栖息地
The rufous-necked foliage-gleaner is found in coastal hills and the western slope of the Andes in Ecuador's El Oro and Loja provinces and in northwestern Peru as far south as the Department of Lambayeque. It inhabits montane evergreen forest and tropical deciduous woodlands, where it favors bamboo, streamsides, and shady ravines. In elevation it mostly ranges from 1,000 to 2,600 m (3,300 to 8,500 ft) but occurs occasionally as low as 400 m (1,300 ft) and as high as 2,900 m (9,500 ft).

行为
The rufous-necked foliage-gleaner is a year-round resident throughout its range.<p>The rufous-necked foliage-gleaner feeds mostly on arthropods. It typically forages singly or in pairs and readily joins mixed-species feeding flocks. It mostly forages from the forest's understory to its mid levels. It gleans and probes for its prey among debris, moss, bamboo stems, ferns, and bromeliads while hitching along branches and trunks. It occasionally forages in leaf litter on the ground.<p>The rufous-necked foliage-gleaner is thought to breed in the local wet season of January to May. Nothing else is known about its breeding biology.<p>The rufous-necked foliage-gleaner's song is "a harsh, nasal 'chick, chick, che-che, tirrrrrr', 2–3 seconds long, final note downward-inflected". Its contact call has been described as a "sharp, nasal 'ank' or 'chech' ".

Ruddy Kingfisher
Halcyon coromanda
Dark rusty-orange kingfisher with thick lipstick-red bill. Bright azure blaze on rump most evident on flying birds. Shy and seldom seen in the open, instead preferring heavily shaded waterways in thick, tangled forests. Gives a loud descending rattle on breeding grounds; wintering birds silent.
Russet-naped Wood-Rail
Aramides albiventris
Large, brightly colored, chicken-like rail of freshwater marshes and damp woodland, less often occurs in mangroves. Unlike many rails, can be conspicuous, even bold, walking in the open along the edge of ponds and rivers, twitching its short black tail; usually seen singly or in pairs. Note long yellowish bill, hot-pink legs, and gray head and neck contrasting with orangey breast. Similar to Gray-cowled Wood-Rail, but barely any range overlap, and Russet-naped has a bright reddish-brown patch on the back of the head.
Tawny-backed Fantail
Rhipidura superflua
A small brown songbird with a long tail that is often cocked and regularly fanned. Rich rufous on the back and rump, with a contrastingly darker pale-tipped tail. Has a brown head with a buff brow, a white throat bordered with a black necklace, and pale buff underparts. Singles and pairs can be found in forest in the foothills and mountains, often within mixed-species flocks. Distinctive in its limited range on Buru, where it is the only brown-backed fantail. Song a high-pitched series of six or more descending whistles. Call is a metallic “tew.”
