TL;DR: The amount of sequence divergence among basal passeriforms and members of the Corvida, as well as available fossil evidence for Australian corvidans, suggest that cnemophilines represent an ancient lineage within the corvoid radiation.
Abstract: The cnemophiline 'birds of paradise' (Cnemophilinae) and Macgregor's 'bird of paradise' (Macgregoria) have traditionally been included in the Paradisaeidae although their relationships within the group have been enigmatic and subject to repeated discussion in the literature. Here we use sequences from two mitochondrial genes, cytochrome b and cytochrome oxidase I, along with a suite of morphological characters, to investigate their relationships to paradisaeids and other members of the passerine Parvorder Corvida. The combined data strongly support the removal of both groups from the birds of paradise: the cnemophilines are basal members of the Corvoidea and Macgregoria is a member of the Meliphagoidea and embedded in the honeyeaters (Meliphagidae) close to the genus Melipotes. The amount of sequence divergence among basal passeriforms and members of the Corvida, as well as available fossil evidence for Australian corvidans, suggest that cnemophilines represent an ancient lineage within the corvoid radiation. Because cnemophilines and Macgregoria have been placed at the base of the paradisaeid tree, hypotheses of morphological, behavioural and ecological character-state transformations within the family will require reanalysis.
TL;DR: A new species of smoky honeyeater from the Foja Mountains of western New Guinea is described, which possesses a fleshy pendant suborbital wattle, unique in the genus Melipotes, among other characteristics that distinguish it from all congeners.
Abstract: We describe a new species of smoky honeyeater from the Foja Mountains, an isolated range in western New Guinea (Papua Province, Indonesia). A common inhabitant of montane forest and forest-edge in this little-known north coastal range, this species possesses a fleshy pendant suborbital wattle, unique in the genus Melipotes, among other characteristics that distinguish it from all congeners. This fleshy wattle provides a morphological link between Melipotes and the monotypic genus Macgregoria, an alpine inhabitant of the Central Ranges of New Guinea, traditionally treated as a bird of paradise (e.g., Frith and Beehler 1998) but now regarded as the sister genus to Melipotes (Cracraft and Feinstein 2000). The presence of an endemic meliphagid species in the Foja Mountains highlights the biogeographic significance and conservation importance of this geographically isolated upland forest tract, which is also home to the endemic Golden-fronted Bowerbird (Amblyornis flavifrons) and Berlepsch's Parotia (...
