Polyphyletic Origin of the Genus Amaurornis Inferred from Molecular Phylogenetic Analysis of Rails

The Rallidae (a family of wading birds) are distributed worldwide and occupy diverse habitats (Slikas et al. 2002). Apart from the coots and some moorhens, most of these birds live on the ground in dense vegetation and are very difficult to observe (Wang 2006). About 15 endemic rail species are distributed in eastern Asia (Wang 2006), but unfortunately, most of the habitats for these taxa are disappearing rapidly and some species are becoming endangered. Previous phylogenetic studies of some Asian rails were unable to resolve some of the deeper relationship patterns (Livezey 1998; Sibley and Ahlquist 1990; Slikas et al. 2002). In this study, we took a molecular approach, using mitochondrial DNA sequences to examine the relationships among these species.
