Chestnut-backed Owlet
Glaucidium castanotum
Small owl lacking ear tufts, with chestnut mantle and pale belly with streaked flanks. Crepuscular and diurnal, occurring singly or in pairs in wet rainforest, or neighboring woods. Chestnut back and streaked flanks of Chestnut-backed Owlet separate it from the similar Jungle Owlet, and Chestnut-backed also prefers the wetter region of the island. Call is a series of barbet like “kurr-kurr-kurr” notes, often followed by harsh “kao-kao” yaps, similar to Jungle Owlet, but slightly lower-pitched.
识别特征
The chestnut-backed owlet is small and stocky, measuring 19 cm (7.5 in) in length. It resembles the jungle owlet in shape, size and appearance but the upperparts, scapulars and wing coverts are mainly chestnut brown, with darker barring. The underparts are white with blackish shaft-streaks. The facial disc is mainly brown and the eyes are yellow. There is a white neckband. Sexes are similar in appearance, with no sexual dimorphism.

分布与栖息地
The chestnut-backed owlet is a common resident bird in the wet zone forests of Sri Lanka, and can be seen easily at sites such as Kitulgala and Sinharaja. Historical reports of its distribution by Legge include many parts of the southern half of Sri Lanka, especially the hills and the wet-zone low country extending to the outskirts of Colombo. In recent times, its range has shrunk greatly, and it is now found sparingly in the remaining forests of the wet zone and the adjoining hills at altitudes of up to 6,500 ft (2,000 m) above sea level.

行为
This species is diurnal and is frequently seen in the day, especially in the evening. The flight is deeply undulating. It can often be located by the small birds that mob it while it is perched in a tree. It frequents tops of tall trees, usually on steep hill-sides and hence is often missed. It feeds mainly on insects, such as beetles, but also captures mice, small lizards, and small birds mostly when the young are being fed. The call is a slow kraw-kraw and carries for a long distance. It nests in a hole in a tree, laying two eggs.

Orange-eyed Thornbird
Phacellodomus erythrophthalmus
Medium-sized thornbird with a long tail. Note orange eyes and rufous forehead, throat, and tail while the body is largely brown. Similar to Orange-breasted Thornbird, but has orange rather than dark eyes. Found in pairs on the edge of humid forests, usually near marshes and water bodies where it builds huge stick nests. The song is loud and nasal, usually delivered as a duet.
Blue-breasted Fairywren
Malurus pulcherrimus
Small bird with a very long blue-gray tail held cocked, found from southwestern Western Australia to the Eyre Peninsula of South Australia, where it prefers coastal heath and drier woodland areas. Breeding male has a bright blue helmet, bluish-black breast, blue patch on back, and chestnut shoulders. Female grayish overall, with long blue-gray tail and reddish bill. Nonbreeding male resembles female but has black bill and narrow pale eyering.
Giant Conebill
Conirostrum binghami
Scarce to locally fairly common (rare in Chile) nomadic bird of Polylepis woodland in the high Andes. Found as singles or pairs, foraging by creeping on trunks and branches of Polylepis trees, at times in association with mixed-species feeding flocks. Can be confiding, and at other times may fly off long distances in search of other Polylepis patches. No similar species: note pointed bill, white cheeks, and bright rusty underparts, which blend well with Polylepis bark.
