Distribution of quail-thrushes in the Northern Territory, and their taxonomic relations

Abstract

Cinclosoma marginatum and C. castanotum occur sympatrically but in different habitats in the south-west of the Northern Territory. The implications of the occurrence of C. marginatum as far east at Mt Olga are discussed. Evidence is presented which suggests that the taxonomic status of C. marginatum, castaneothorax, cinnamomeum and alisteri should be re-examined. C. marginatum and C. castaneothorax are probably conspecific; C. cinnamomeum is possibly more closely related to C. alisteri.
