Gray-backed Cisticola
Cisticola subruficapilla
Medium-sized, streak-backed cisticola of uplands. Varies geographically: gray-backed and streak-breasted in the south, and rufous-backed and plain-breasted in the north. Found in fynbos and karoo habitats, usually in areas with a mix of rocks, shrubs, and grass. Generally inconspicuous; seen singly or in pairs. Song is a short, explosive, accelerating trill. Calls include a rising, two-part “chu-cheee”. Very similar to Wailing Cisticola, but has a different voice, a smaller bill, less buffy underparts, and doesn’t show rufous in the wing.
识别特征
The grey-backed cisticola is a small, 13–14 cm long, vocal, dull-coloured bird with a dark rufous crown to its reddish head. It has a rufous panel in the folded wing. The grey bill is short and straight, and the feet and legs are pinkish-brown. The eye is light brown.<p>The southern form, "grey-backed cisticola" proper, found in southern Namibia and South Africa has a grey back heavily streaked with black. Its underparts are greyish white. Although cisticolas can be very similar in plumage, this greyish subspecies is quite distinctive. The northern subspecies has a brown back heavily streaked with black and cold buff underparts. It is very similar to the wailing cisticola, Cisticola lais, of eastern South Africa, but that species has warmer buff underparts and does not overlap in range.<p>The sexes are similar, but juvenile birds are duller with a yellow face.<p>The call of the grey-backed cisticola is a soft prrrrt followed by a sharp wheee phweee.

保护状况
This common species has a large range, with an estimated extent of 820,000 km². The population size is believed to be large, and the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as least concern.

Taiwan Hwamei
Garrulax taewanus
Lightly streaked brown songbird with starkly pale eyes found in edge habitat and scrubby areas in Taiwan. Chinese Hwamei, which has been introduced in Taiwan, has an unstreaked head, dark eyes, and distinctive bluish lines behind the eyes. Hybridization threatens this species’ survival. An accomplished songster, but unlike the Chinese Hwamei, does not mimic other species.
Black-bellied Thorntail
Discosura langsdorffi
Tiny, coquette-like hummingbird. Males are iridescent emerald green with a black belly, bold white rump band, short crest, and long, straight tail feathers. Females are similar, but are duller below with a shorter tail. Compared to the similar Festive Coquette, females have darker plumage. Usually found in mature rainforest, where it forages at flowering trees at all levels of the forest.
New Britain Dwarf-Kingfisher
Ceyx sacerdotis
A small kingfisher with deep purplish-blue upperparts and fiery orange underparts with a white neck spot and bright orange legs. Bill is blackish-red above and purer red below, but appears entirely red in the field. Prefers mature and dense secondary forest, often perching low. No other dwarf-kingfisher shares its range. Told from Common Kingfisher by smaller size and red rather than black bill. Call apparently nearly identical to that of other Melanesian dwarf-kingfishers: a high-pitched, weak repetitive whistle, often given in flight.
