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...
The Cinnamon Ibon inhabits the canopy of cloud‐forest of Mindanao Island in the Philippines, and has until now been classified as an aberrant member of the Zosteropidae (white‐eyes). We assessed the systematic position of this enigmatic species using DNA sequence data (two mitochondrial markers, two nuclear introns and two nuclear exons) and broad taxon sampling. The species was robustly placed among...
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...
Clutch sizes of gamebirds decrease in a hyperbolic fashion towards the equator, but their clutch investment (total clutch mass as a proportion of female body weight) does not vary with latitude, regardless of whether body mass and phylogeny are factored out. In contrast, clutch sizes of wildfowl increase towards the tropics, but when corrected for body mass and phylogeny, no latitudinal pattern remains...
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...
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...
We describe Cinclodes espinhacensis (Furnariidae), a new species discovered at high elevation in the southern portion of the Espinhaço Range, in the state of Minas Gerais, southeastern Brazil. This new taxon is closely related to the Long‐tailed Cinclodes Cinclodes pabsti, endemic to Serra Geral, southern Brazil. We present diagnostic morphological, genetic and vocal characters that support the rank...
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),...
We investigated phylogenetic relationships among Otus scops owls from Socotra Island, the Arabian Peninsula and East Africa using molecular, vocalization and biometric data. The Socotra Scops Owl Otus senegalensis socotranus, currently treated as a subspecies of the African Scops Owl Otus senegalensis, is more closely related to the Oriental Scops Owl Otus sunia and to the endemic Seychelles Scops...
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...
The Pygmy Bushtit is confined to the montane forests of Java. It is the world's smallest passerine and morphologically resembles a small, drab long‐tailed tit or bushtit (Aegithalidae). In its behaviour the Pygmy Bushtit show similarities with the members of the Aegithalidae, but owing to its small size and isolated geographical distribution relative to the other members of the Aegithalidae, it has...
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 bulbuls comprise an ecologically important group of frugivorous, seed‐dispersing birds found in Asia and Africa. Although several studies have examined the phylogenetic relationships of subsets of bulbul species, a comprehensive phylogeny of the family Pycnonotidae has hitherto been lacking. We used publicly available sequences generated from previous phylogenetic studies, augmented by new sequences...
The recently described Bare‐faced Bulbul Pycnonotus hualon from Lao PDR has a very distinct morphology and habitat (karsts). Mitochondrial and nuclear data from the type material demonstrated that P. hualon is sister to members of the genus Spizixos. To highlight its unique morphology and phylogenetic distinctiveness, we describe a new monotypic genus for the Bare‐faced Bulbul.
The globally distributed avian family Motacillidae consists of five to seven genera (Anthus, Dendronanthus, Tmetothylacus, Macronyx and Motacilla, and depending on the taxonomy followed, Amaurocichla and Madanga) and 66–68 recognized species, of which 32 species in four genera occur in sub‐Saharan Africa. The taxonomy of the Motacillidae has been contentious, with variable numbers of genera, species...
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...
Mitochondrial genes were sequenced from four specimens of the extinct Canary Islands Oystercatcher Haematopus meadewaldoi and compared with African Oystercatcher Haematopus moquini, Eurasian Oystercatcher Haematopus ostralegus and an old unidentified extralimital ‘black’ oystercatcher specimen from The Gambia. At these loci, H. meadewaldoi was approximately 99.65% identical to multiple Eurasian Oystercatcher...
The seasonal timing of moult in migratory birds is an adaptation to cope with time constraints in the annual cycle. Kiat and Izhaki analysed moult patterns in Palaearctic passerines and rejected the proposition that seasonally divided moult is an endogenously controlled strategy. Instead, they advocated the view that it occurs due to a flexible and opportunistic timing of moult. In contrast, we argue...
