'' Salpornis '' is a genus of bird which is usually included in the Certhiidae family. The genus has in the past been included with the nuthatches in the family Sittidae or placed in a family of its own, the Salpornithidae. Molecular phylogenetic analyses show them to be definitely within the Certhioidea but still leaves some uncertainty about their placement in relation to the genera ''Sitta'', ''Tichodroma'' and ''Certhia''. While they appear similar to the treecreepers (''Certhia''), they do not use their tails to support them while climbing and some molecular evidence shows them to be closer to the nuthatches (''Sitta'') while another study suggests a closer relation to the wallcreeper ''Tichodroma muraria''.〔 The generic name is derived from the Greek ''salpinktes'' for wren and ''ornis'' for bird. The tail has twelve feathers and is rounded at the tips. The nostril is exposed and there are no rictal bristles. The tongue ends in five bristles. The genus has two species with the African species earlier considered as a subspecies. Differences in size, calls and mitochondrial DNA sequences have supported the splitting of the African and Indian populations. * Indian spotted creeper (''Salpornis spilonotus'') * African spotted creeper (''Salpornis salvadori'') with four subspecies. ==References== 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「Salpornis」の詳細全文を読む スポンサード リンク
