The wood pipit or woodland pipit (''Anthus nyassae'') is a small passerine bird belonging to the pipit genus ''Anthus'' in the family Motacillidae. It was formerly included in the long-billed pipit (''Anthus similis'') but is now frequently treated as a separate species. It is a bird of miombo woodland in south-central Africa, unlike the long-billed pipit which inhabits open grassland. It perches in trees when flushed but forages on the ground for invertebrates. It is 16-18 centimetres long. The upperparts are warm brown with dark streaks while the underparts are pale with some streaking on the breast. The bird has a dark eyestripe, white supercilium and pale outer tail-feathers. Juveniles have dark spots above and have more streaking below than the adults. The bird's song is high-pitched and monotonous. The long-billed pipit is very similar but has a slightly longer bill and tail, a smaller pale area in the outer tail-feathers and a slightly lower voice. The range of the wood pipit extends from south-east Gabon eastwards to southern and western Tanzania and southwards as far as north-east Namibia, northern Botswana, Zimbabwe and north-west Mozambique. At least three subspecies are recognized: ''A. n. nyassae'', ''A. n. frondicolus'' and ''A. n. schoutedeni''. Some authors recognize a fourth subspecies, ''A. n. chersophilus''. ==References== * Sinclair, Ian & Ryan, Peter (2003) ''Birds of Africa south of the Sahara'', Struik, Cape Town. * Van Perlo, Ber (1999) ''Collins Illustrated Checklist: Birds of Southern Africa'', HarperCollins, London. 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「Wood pipit」の詳細全文を読む スポンサード リンク
