As populations diverge, genetic differences accumulate across the genome. Spurred by
rapid developments in sequencing technology, genome-wide population surveys of natural …

The colorful phenotypes of birds have long provided rich source material for evolutionary
biologists. Avian plumage, beaks, skin, and eggs—which exhibit a stunning range of cryptic …

Structural variation (SV) constitutes an important type of genetic mutations providing the raw
material for evolution. Here, we uncover the genome-wide spectrum of intra-and interspecific …

INTRODUCTION Organisms in the early stages of speciation provide an opportunity to
understand the processes that govern reproductive isolation between taxa. Ecological or …

Uncovering the genetic basis of species diversification is a central goal in evolutionary
biology. Yet, the link between the accumulation of genomic changes during population …

The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Hybridization is widespread in nature and, in some instances, can result in the formation of a
new hybrid species. We investigate the genetic foundation of this poorly understood process …

The evolution of genetic barriers opposing interspecific gene flow is key to the origin of new
species. Drawing from information on over 400 admixed genomes sourced from replicate …

Coloration is an important target of both natural and sexual selection. Discovering the
genetic basis of colour differences can help us to understand how this visually striking …

Organismal adaptations are the hallmark of natural selection. Studies of adaptations in avian
systems have been central to key conceptual and empirical advances in the field of …
