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.

行为
One or two individuals are usually encountered, but flocks may be found in winter. It frequently wags its tail. Its song is a repeated tchreep-churup, and the call sshik is given when the bird is flushed. It eats invertebrates and seeds. Breeding has been recorded from July to February in Zimbabwe and August to December in South Africa. The nest is an open cup built on the ground.

Black-tailed Whistler
Pachycephala melanura
Chunky, rounded songbird with heavy thick bill. Found across a wide range of habitats across its range: largely mangroves in Australia, but also inhabits freshwater swamps in New Guinea and forests and forest edge on smaller islands. Male has an olive-yellow back, black head, white chin, bright yellow underparts, and thick yellow hindcollar. Female plain gray above, paler gray below, with yellow undertail and in some subspecies a yellow belly. Overlaps very marginally with the very similar Golden Whistler in eastern Queensland, but note mangrove habitat as well as slightly longer bill and darker uppertail; also note significant yellow on underparts in female and different song. Vocalizations include variations on whistled songs, sometimes with a whip-like ending.
Sahul Sunbird
Cinnyris frenatus
Tiny and active sunbird of forest edges, parks, and gardens; ranges from Sulawesi east to the northern Moluccas, New Guinea, and northeastern Australia. Both sexes have a plain olive back, a yellow belly, and white tail edges that are flared out in flight. The male flashes an iridescent blue throat while the female has a yellow throat and eyebrow. In parts of range, female Sahul may be confused with female Black Sunbird; note that species’ unmarked gray head and shorter, less curved bill. Gives a buzzy, twittering song, as well as a rising “dwee”, a familiar sound even in cities. Formerly grouped with other, closely related species under “Olive-backed Sunbird.”
Timor Oriole
Oriolus melanotis
Male is a distinctive oriole with a green head, dark mask, and orange-red bill. Duller female is brown above and paler below, with a dark mask and black bill. Juveniles are heavily streaked. Singles and pairs can be found in lowland forest patches, woodlands, mangroves, and cultivated areas. Females resemble Helmeted Friarbird, but lacks that species’ casque, naked facial skin, and a prominent nostril on the blunter-tipped bill. Gives a “k’WOW” and descending “k’we-hoo.”
