Pale Batis
Batis soror
A typical black, white, and gray batis. Note the chest band, which is black in males and rufous in females. Females also have a pale rufous patch at the center of their otherwise white throat. Found in miombo broadleaf woodland and coastal forest, often in pairs. Similar to Chinspot Batis but paler overall, and the black breast band of the male is narrower. Also paler overall than Eastern Black-headed Batis. The variable song is usually a fast series of identical high-pitched whistled notes.
识别特征
The pale batis is an active, black, white and grey bird which is pale grey above with a black face mask bordered by a thin white supercilium, yellow eye and a pale grey back, mottled with faint white spots. It has white underparts marked with a black band across the breast in males; females have a pale rufous breast band and a similar coloured spot on the chin. The bill and legs are black. Immature birds are similar to the female except that the breast band is browner and the underparts have a buffy wash. The pale batis measures 10.5–11.5 cm (4.1–4.5 in) in length and weighs 8–13.1 g (0.28–0.46 oz).<p>The territorial call of the pale batis is a repeated, mournful, long and piping 3-note “pook pook pook” which is repeated up to 12 times at a constant rate, with which the female duets giving excited "wik-wik" calls. Otherwise the repertoire consists of typical batis bill snaps, churrs and whistles.

分布与栖息地
Eastern Africa from coastal Kenya including the Arabuko Sokoke National Park south through eastern and south-eastern Tanzania, the islands of Zanzibar and Mafia, to Mozambique as far south as the Save River, inland to south eastern Malawi, and the east-facing slopes of the Eastern Highlands of Zimbabwe. The pale batis typically occurs in lowland miombo woodland, normally below 500 m (1,600 ft) in coastal woodlands where there is a mosaic of forest and dense scrub. Can also be found in mopane and acacia around the edges of its distribution. In the Eastern Highlands of Zimbabwe it is found up to 1,500 m (4,900 ft) above sea level in tall Uapaca kirkiana stands, thickets of Philippia spp. and woodland dominated mountain acacia.

Masked Antpitta
Hylopezus auricularis
Medium-sized antpitta of floodplain forest, particularly with palmetto understory, along the confluence of the Ríos Madre de Dios and Bení in the Riberalta area. The only antpitta in range with dark chevrons on underparts or a blue-gray cap. Forages on or near the ground, but generally perches 1-2 m up in the understory or midstory to sing at dawn. Visually distinctive in range, but song deceptively similar to, and perhaps indistinguishable from, local songs of Amazonian Antshrike. Call a more distinctive three to four-part descending whistle.
Brown Tanager
Orchesticus abeillei
Large and rather uncommon tanager found in the canopy of humid forests where it usually accompanies mixed-species flocks. Plain brown overall with a cinnamon face, wings, and tail and a dark mask running through the eyes. Its plumage mimics the Buff-fronted Foliage-gleaner, with which it is easily confused and it may even occur in the same flock, but note the tanager’s thicker bill. The thin rising song is very high-pitched.
Common Reed Warbler
Acrocephalus scirpaceus
Rather plain medium-sized warbler: warm brown above with narrow pale spectacles, pale buffy below. Can be very difficult to separate from other reed warbler species. Most populations breed in reed or sedge beds, both pure and mixed with bushes, often wandering to adjacent scrub and thickets. “Mangrove” Reed Warbler is a resident in mangroves along the Red Sea. Non-breeding migratory birds may wind up in a wide range of habitats, from marshes to mangroves, to acacia scrub and cultivation. Often heard but can be hard to see: prolonged song much like Sedge Warbler but more even-paced and melodic, without rough and jerky phrases. Calls include a low “chuk” and rattled “chrrt.”
