Bates's Sunbird
Cinnyris batesi
A very small nondescript sunbird with a short orange-based bill that curves uniformly along its length; easily mistaken for females of other sunbirds. The only features on the olive upperparts are indistinct paler eyebrows and lines running under the eyes, and yellow edging to the wings. Although often hidden, the male has yellow or whitish (not red) tufts at the shoulders. Singles are local and inconspicuous at the edges of lowland and riverine forest, sometimes entering secondary growth; it joins mixed-flocks and is frequently attracted to epiphytes in mossy clumps. Calls a high-pitched “tseeep” and trills. Little Green and Fraser’s sunbirds are similar to Bates’s but brighter, with straighter bills and more distinct yellowish eye-rings; Ursula’s Sunbird has a long decurved bill and grayish face and underparts.
识别特征
Bates's sunbird is a very small dull green sunbird with a short, decurved bill a short tail and a yellowish belly. The male has dark olive upperparts, except for a vague pale supercilium, with paler greyer underparts with a pale buffy centre to the belly. The wings are dark brown with pale fringes and the tail is black with wide olive edges and tips to the outer tail feathers. There are long wispy yellow feathers on the sides of the breast, in the otherwise similar female these feathers are whiter and may be much reduced in length. They measure 9–10 cm in length and weigh 5.7–7g. Given the species overall drab plumage and furtive habits, it can be easily overlooked.

Mangrove Robin
Melanodryas pulverulenta
Small round songbird of dense mangrove areas, particularly the large stilt-rooted mangroves. White below, dark gray above, with blackish wings and white patches on sides of black tail. Distinctive species, much more rotund than other white-chinned bird species in this habitat (e.g., female Shining Flycatcher). Voice is a plaintive, slow, whistled note, usually repeated.
Wire-tailed Manakin
Pipra filicauda
Spectacular manakin with very long tail filaments and piercing white eyes. Males are bright yellow from the face to the underparts and bright red from the crown to the mantle; otherwise they are black. Females are dull olive-green with a yellow tinge to the chin and breast and have shorter tail filaments. Usually found near streams in humid forests, including gallery forests and old second growth.
Somali Fiscal
Lanius somalicus
A small black, white, and gray shrike. The sexes look similar. Note the white patches at the bottom middle and near the end of the wing. Along with the white outer tail, these can be conspicuous in flight. Found in dry savanna and grassland. Perches up conspicuously, often in pairs. Very similar to Taita Fiscal, but has multiple white patches on each wing instead of just one. The repetitive vocalizations include scratchy notes, usually higher and rougher than those of Taita Fiscal, often delivered in a rising pattern.
