Taxa classified as subspecies may in fact be cryptic species. We assessed the taxonomic status of the Blue‐throated Flycatcher Cyornis rubeculoides complex in India, which consists of several forms with similar plumages and song. We used mitochondrial and nuclear DNA, plumage traits, and detailed song analysis to ascertain the taxonomic status of the different forms. The molecular data identified...
We re‐evaluated the taxonomy of the Striated Prinia Prinia crinigera–Brown Prinia P. polychroa complex using molecular, morphological and vocal analyses. The extensive seasonal, sexual, age‐related, geographical and taxon‐specific variation in this complex has never before been adequately studied. As no previous genetic or vocal analyses have focused on this group, misinterpretation of taxonomic signals...
The Rufous‐headed Robin Larvivora ruficeps is one of the world's rarest and least known birds. We summarize the known records since it was first described in 1905 from Shaanxi Province, central China. All subsequent Chinese records are from seven adjacent localities in nearby Sichuan Province. We studied its phylogenetic position for the first time using mitochondrial and nuclear markers for all species...
The taxonomy of the Narcissus Flycatcher Ficedula narcissina–Yellow‐rumped Flycatcher Ficedula zanthopygia complex from East Asia has long been debated. Most authors recognize two species: F. narcissina, with the subspecies narcissina (most of Japan and Sakhalin Island), owstoni (south Japanese islands) and elisae (northeast China) and F. zanthopygia (monotypic), although species status has been proposed...
We estimated a phylogeny for 10 taxa currently placed in four polytypic species that collectively encompass the African ‘brown buntings’: Cape Bunting Emberiza capensis, Cinnamon‐breasted Bunting Emberiza tahapisi, Lark‐like Bunting Emberiza impetuani and House Bunting Emberiza striolata. We made use of the mitochondrial cytochrome b gene and the nuclear introns 6–7 of ornithine decarboxylase (ODC),...
The Arctic Warbler Phylloscopus borealis breeds across the northern Palaearctic and northwestern‐most Nearctic, from northern Scandinavia to Alaska, extending south to southern Japan, and winters in Southeast Asia, the Philippines and Indonesia. Several subspecies have been described based on subtle morphological characteristics, although the taxonomy varies considerably among different authors. A...
The Scrub Warbler, which inhabits arid areas from North Africa to western Asia, has long been thought to be closely related to cisticolid warblers. However, analyses based on two mitochondrial and four nuclear loci place this species sister to the mainly Asian Cettiidae (bush warblers, tesias, etc.). Superficial morphological similarity to cisticolid warblers has previously clouded the species true...
We present molecular evidence that Neumann’s Warbler Hemitesia neumanni is deeply nested within the Cettiidae. The species’ distribution in the Albertine Rift of East Africa is intriguing, as the family Cettiidae is principally an Asian radiation. This disjunct distribution could be a result of colonization of Africa by long‐distance dispersal, or the Cettiidae may at some point in the past have had...
A new species of Phylloscopus warbler, which we name Phylloscopus calciatilis Limestone Leaf Warbler, is described from central and northern Vietnam and central and northern Laos; it probably also breeds in southernmost China. In morphology, the new species is very similar to Sulphur‐breasted Warbler Phylloscopus ricketti, but it is smaller with a proportionately larger bill and rounder wing. Its...
