Bisbita del Vaal

Identificación

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.

Taxonomía

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.
