Journal ArticleDOI
No evidence that carotenoid pigments boost either immune or antioxidant defenses in a songbird
Rebecca E. Koch,Andreas N. Kavazis,Dennis Hasselquist,Wendy R. Hood,Yufeng Zhang,Yufeng Zhang,Matthew B. Toomey,Geoffrey E. Hill +7 more
TL;DR: Results add further challenge to the assumption that carotenoids are directly involved in supporting physiological function in vertebrate animals, and suggest that they may play little to no direct role in key physiological processes in birds.
Journal ArticleDOI
Plumage coloration is a sexually selected indicator of male quality
TL;DR: Results of field studies indicate that females prefer to mate with colourful males and that plumage brightness correlates with a male's capactity for parental care and perhaps its genotypic quality.

TL;DR: A roadmap of technological advances and key questions for the future of animal coloration research are provided, to identify hitherto unrecognized challenges for this multi- and interdisciplinary field.
Journal ArticleDOI
Female house finches prefer colourful males: sexual selection for a condition-dependent trait
TL;DR: Male coloration was independent of age, size, dominance, vocal activity and movement rate in these experiments, and females showed no significant association preference for any of these male characters, while paired males were significantly more colourful than males in the population at large.
Journal ArticleDOI
Choosing mates: good genes versus genes that are a good fit
Herman L. Mays,Geoffrey E. Hill +1 more
TL;DR: The interplay between these two contrasting forms of female mate choice presents an exciting empirical and theoretical challenge for evolutionary ecologists.
