Red-tufted Sunbird
Nectarinia johnstoni
Large, long-billed dark sunbird with red shoulder tufts that are often hidden. Males have very long tail streamers and are dark iridescent green in breeding plumage, and gray-brown with some green patches in non-breeding plumage. Females are dark gray-brown. Found in grassland and heath habitats at very high elevations. Vocalizations include metallic calls and a quick, scrambled song. Similar to Malachite Sunbird, but generally found at higher elevations, and looks darker in all plumages; female lacks white edges to the tail.
识别特征
The scarlet-tufted sunbird is a large sunbird. Adult males have long tails, up to about 20 centimetres (7.9 in) in length, and scarlet pectoral tufts up to about 10 millimetres (0.39 in) wide. These tufts can be seen in flight and when the wings are rearranged, but not in perched birds. The head is black and the upper parts are metallic green, appearing almost black from a distance. The rump is bluish and the wings and tail black, the latter having elongated central feathers. The underparts are iridescent green, fading to bluish-violet on the upper belly and black on the lower belly. The female has brownish-grey upper parts, brownish-black wings and a dark brown tail. The underparts are whitish with dark mottling. The pectoral tufts are smaller than those of the male and may be rather more orangey-red. The juvenile is similar to the adult female but lacks the pectoral tufts.

分布与栖息地
The scarlet-tufted sunbird is found at very high altitudes in the Afroalpine Rwenzori-Virunga montane moorlands and East African montane moorlands, though also found at lower altitudes. Its normal range is on several disjunct areas of montane forest and moorland between 3,000 and 4,500 m (9,843 and 14,764 ft) in altitude, which encompasses a number of zones of vegetation. It is especially associated with giant lobelia, feeding on the nectar and insects on the plants, and using the tall flowerheads as song-posts. At lower altitudes it feeds on Protea and other plants.

Grande Comore Brush-Warbler
Nesillas brevicaudata
A robust, medium-sized brown bird with a long, spiky tail. Endemic to the island of Grand Comoro. Found at middle and high elevations in humid forest, including thickets, clearings, edges, and tree heath at high elevations. An inconspicuous bird, except by voice, that skulks in thick vegetation. The vocalizations are “chek” and “veet” notes often given in a series. There are no similar warblers on Grand Comoro, so identification is simple.
Rufous Cisticola
Cisticola rufus
A small, brownish upland cisticola. Remarkably plain: brown on the upperparts and buff below. The unmarked face often has a gentle expression. Found locally in both thorn savanna and broadleaf woodland. Very similar in appearance to Siffling Cisticola, but generally has warmer coloration and lacks streaking on the back. Also similar to Foxy Cisticola, but less rufous, and there is minimal overlap in range. Similar to Dorst’s Cisticola, but smaller, and the cap and back are roughly the same color. Rufous Cisticola’s unimpressive song consists of 2-3 high-pitched, squeaky notes in a descending pattern, very similar to the song of Siffling Cisticola.
Red-shouldered Spinetail
Synallaxis hellmayri
Angry-looking bird with a long spiky tail and brown plumage contrasting with a black throat and a rusty shoulder patch. Occurs in arid, scrubby woodlands where normally forages on or close to the ground. The song is a repetition of a short, fast “quebéc.”
