Long-billed Tailorbird
Artisornis moreaui
Inconspicuous, apalis-like grayish warbler with a long tail, straight thin bill, and buff-brown forehead. Isolated population in Mozambique, sometimes considered a different species (Njesi Tailorbird), is smaller, darker, and browner on the head. Singles and pairs are very low density, shy and creep slowly through the undergrowth and canopy, especially nearby streams; sometimes joins mixed-species flocks. Song a pleasant sweet bouncing “eeh-yuh, eeh-yuh, eeh-yuh” or strident “peelik-peelik-peelik”, sometimes joined in duet with a dry buzzing “dzit”; call a high-pitched “chhet” like a squeaky dog’s toy. Similar Brown-headed Apalis is shorter-billed than Long-billed Tailorbird and has white tips to the tail.
识别特征
The long-billed forest warbler is a small, plump, inconspicuous warbler, growing to a length of about 10 cm (4 in). The upper parts are greyish and the underparts a rather paler grey. The head sometimes has a brownish tinge, and bears filoplumes. The beak is long and slender, and the tail is long and is frequently cocked when the bird is excited. The call is a distinctive metallic "peedoo peedoo"; this bird is easier to detect by hearing its call than by sight. It is similar in appearance to the red-capped forest warbler (Artisornis metopias), but that species has a much shorter beak, a more russet head and a rust-washed breast.
分类信息
The long-billed forest warbler was formally described in 1931 by the British zoologist William Lutley Sclater from specimens collected by Reginald Ernest Moreau in forest near Amani in the Usambara Mountains of eastern Tanzania. Sclater coined the binomial name Apalis moreaui with the specific epithet chosen to honour the collector. This warbler is now placed with the red-capped forest warbler in the genus Artisornis that was introduced in 1928 by the American ornithologist Herbert Friedmann.<p>Two subspecies are recognised:<p>Some taxonomists treat A. m. sousae as a separate species, the Mozambique forest warbler.

分布与栖息地
Subspecies moreaui is endemic to the East Usambara plateau in Tanzania. In the Usamabaras it is present in the Amani Nature Reserve and the Nilo Nature Reserve. The East Usambara plateau is known as a biodiversity hotspot and has many endemic species.<p>The Mozambique forest warbler (Artisornis moreaui sousae) is endemic to the Njesi Highlands of northern Mozambique. Its natural habitat is evergreen Afromontane forest patches and riparian forests. It has been observed between 1,430 and 1,850 meters elevation on the three highest mountains – the Njesi Plateau, Mount Chitagal, and Mount Sanga – in the highlands. It was found in the mid-storey and canopy (never the understorey), particularly around forest gaps and tree falls, forest clearings, and dense vine tangles.

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.
Rufous-shafted Woodstar
Chaetocercus jourdanii
Tiny, mostly green bumblebee-like hummingbird with a straight bill, glittering magenta throat, white chest band and sides of rump, and short forked tail. Female very different, with buffy underparts, dark brown ears, and unforked rufous tail with a black band. Found in cloud forest, edges, second growth, and gardens, with some seasonal movements. Often hard to see, but sometimes perches at the top of bare branches. In Andes, compare to the similar Gorgeted Woodstar; male Gorgeted has longer purple feathers on the throat, and female lacks green central tail feathers. At lower elevations compare with Amethyst Woodstar, in which the male has a longer tail and female has a whitish throat and black tail tipped with white. Restricted to Colombia and Venezuela.
Purple-backed Thornbill
Ramphomicron microrhynchum
Small hummingbird with an extremely short, straight bill. Males are unmistakable: brilliant purple above and green below. Females are green above and whitish below with dense green spotting, especially on the flanks. Both sexes have a fairly long, notched tail. Occurs in the Andes from western Venezuela to Peru. Usually seen singly in the canopy or borders of humid elfin forest near treeline, though can gather in larger numbers at flowering trees. Also ventures into páramo; occasionally descends to lower elevations in the dry season. Seasonal movements are not understood.
