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 …

Birds exhibit remarkable variation in plumage patterns, both within individual feathers and
among plumage patches. Differences in the size, shape, and location of pigments and …

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

The presence of population-specific phenotypes often reflects local adaptation or barriers to
gene flow. The co-occurrence of phenotypic polymorphisms that are restricted within the …

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 …

Avian evolution has generated an impressive array of patterns and colors in the~ 10,000
bird species that exist on Earth. Recently, a number of exciting studies have utilized whole …

Oceanic archipelagos are excellent systems for studying speciation, yet inference of
evolutionary process requires that the colonization history of island organisms be known …

Whole tissue RNASeq is the standard approach for studying gene expression divergence in
evolutionary biology and provides a snapshot of the comprehensive transcriptome for a …

In a hybrid zone between two tropical lekking birds, yellow male plumage of one species
has introgressed asymmetrically replacing white plumage of another via sexual selection …

Coloration traits are central to animal communication; they often govern mate choice,
promote reproductive isolation and catalyse speciation. Specific genetic changes can cause …
