Buffy Pipit
Anthus vaalensis
Large pipit with buffy outer tail feathers and a plain or very diffusely streaked back. Found in open areas with very short grass and also sometimes in agricultural fields. Bobs its tail more frequently and vigorously than other pipits. Call is a quiet chirp, and the song is an unobtrusive series of similar notes. Extremely similar to Plain-backed Pipit but separated by its pink rather than yellowish base to the bill.
识别特征
Its length is 16–18 cm (6.3–7.1 in), and its weight is 23–36.6 g (0.81–1.29 oz). It is often confused with the plain-backed pipit because both species have plain upperparts. The upperparts of the buffy pipit are paler and buffier than the plain-backed pipit. The buffy pipit has a pale supercilium, and its lower mandible has a pinkish base. It has faint markings on the breast, and the belly and flanks are buffy. The juvenile has mottles.
分类信息
This species was described by English naturalist George Ernest Shelley in 1900. The IOC World Bird List recognises five subspecies: A. v. chobiensis in the south of the Democratic Republic of the Congo, southwestern Tanzania, northeastern Namibia, northern Botswana, Zimbabwe and western Mozambique; A. v. neumanni in central Angola; A. v. namibicus in northeastern and central Namibia; A. v. exasperatus in northeastern Botswana; and A. v. vaalensis in southern Botswana and South Africa. A. longicaudatus is an invalid taxon and is included in A. vaalensis. Some authors include subspecies saphiroi and goodsoni of the plain-backed pipit (Anthus leucophrys) in this species.

Leaden Flycatcher
Myiagra rubecula
A long-tailed, slender songbird with fine bill. Males rich blue-gray above, white below, with a blue-gray bib with convex lower edge (curves upward at the edges). Crown paler than throat, lending male a bearded appearance in optimal light. Male Satin Flycatcher has uniformly dark head, blackish (not grayish) tail feathers, and concave bib edge. Female paler blue-gray above, with pale orange throat and breast. Inhabits varied woodlands, perches high in the canopy, often shakes the tail rapidly. Song a repeated two-note whistle; call a loud buzzing “zerp.”
Gray Catbird
Dumetella carolinensis
Medium-sized songbird with a smooth gray body, black cap, and rusty-red undertail coverts. Sexes alike. Occurs in shrubby habitats, especially thickets or second-growth at the edge of forest, often near water. Usually quite skulking, but sometimes pops up conspicuously, especially when singing. Occasionally visits feeders, especially for suet. Listen for complex, jumbled song, which often includes mimicry of other species.
Beaudouin's Snake-Eagle
Circaetus beaudouini
Chunky dark brown raptor with a white belly marked by thin bars. Immatures are brown when perched, and show rufous patches in the underwing in flight. Found in savanna habitats. Soars frequently and sometimes hovers. Very similar to Short-toed Snake-Eagle, but has darker upperparts and narrower dark bars on the belly; the front of the underwings looks white and unbarred in flight. Immature similar to immature Black-breasted and Short-toed Snake-Eagles, but identified by the rufous patches on the underwings.
