Accurate identification of sex in birds is important for the management and conservation of
avian wildlife in several ways, namely in the development of population, behavioral and …

An implicit assumption of speciation biology is that population differentiation is an important
stage of evolutionary diversification, but its significance as a rate-limiting control on …

Changes in this supplement include the following:(1) 4 species (Columba palumbus,
Amazilis amazilia, Ichthyaetus ichthyaetus, and Helopsaltes certhiola) are added to the main …

Mitochondrial DNA usually shows low sequence variation within and high sequence
divergence among species, which makes it a useful marker for phylogenetic inference and …

Background Hybridization provides a unique perspective into the ecological, genetic and
behavioral context of speciation. Hybridization is common in birds, but has not yet been …

We describe the range-wide phylogeography of Blackpoll Warblers (Setophaga striata), a
migratory passerine with a broad breeding range in North America's boreal forest that …

We report here the successful assembly of the complete mitochondrial genomes of the
northern spotted owl (Strix occidentalis caurina) and the barred owl (S. varia). We utilized …

Much of our understanding of vocal geographic variation in birds is based on the dialects of
oscine songbirds that learn their songs. Recent studies have revealed that nonoscine vocal …

We used mitochondrial and nuclear DNA sequences to examine patterns of differentiation
and evolution in the Musophagidae, an avian family endemic to sub-Saharan Africa; …

Rock Nuthatches comprise two morphologically similar species: Western Rock Nuthatch
