The Cape clapper lark (''Mirafra apiata'') is a small passerine bird which breeds in southern Africa. It derives its name from the wing clapping which forms part of the display flight. It was previously considered conspecific with the eastern clapper lark. The Cape clapper lark, ''Mirafra (apiata) apiata'', is found in south-western South Africa, the Agulhas clapper lark, ''M. (a.) majoriae'', in found in the southern Western Cape Province of South Africa as far east as Knysna. Fry, Keith and Urban, in ''The Birds of Africa'', regard ''M. apiata'' and the eastern clapper lark as forming a superspecies with ''M. rufocinnamomea'', the flappet lark, which is found further north. The Cape clapper lark is a species of open grassland and savannah, also inhabiting karoo, fynbos and fallow agricultural land. == Identification == This lark is a 15 cm long bird, with a brown crown, rich rufous underparts, and a strong bill. The Cape clapper lark has grey upperparts and a grey face, and the Agulhas clapper lark has dark brown upperparts, although individual variation means that it cannot always be reliably distinguished from the nominate race. The display commences with an ascending flight with wing flapping. The Cape clapper lark has a slower wing clap compared to the eastern clapper lark, and its otherwise similar call is longer and rises in pitch more. The Agulhas clapper lark has a fast wing clap, and a descending double whistled ''peeeooo'' call. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cape clapper lark」の詳細全文を読む スポンサード リンク
