Avian eggs differ so much in their colour and patterning from species to species that any
attempt to account for this diversity might initially seem doomed to failure. Here I present a …

Recent work suggests that the evolution of egg coloration may have been constrained in
three important ways that have not yet been critically synthesized in any review. First, on …

The arms race between brood parasites and their hosts provides a classic model to study
coevolution. Hosts often reject the parasitic egg, and brood parasites should therefore select …

The signaling hypothesis of eggshell coloration in birds is based on the assumption that
females of species with blue-green eggs signal their phenotypic quality to their mates …

Highlights•We examined correlated evolution between nest and egg characteristics in
birds.•The ancestral state of nests was semi-open with nest sites becoming more …

Egg coloration has been hypothesized to reflect female condition. Because of the proposed
physiological costs associated with deposition of biliverdin pigments and because of their …

It has been recently proposed that the blue-green coloration in eggs of many avian species
may constitute a sexually selected female signal. Blue-green color intensity would reflect the …

Eggshell color is an important shell quality trait that influences consumer preference. It is
also of particular importance with respect to sexual signaling and the physiological and …

A recent hypothesis proposes that the bright colors, especially blue and green, of many
avian eggs may function as signals of female or offspring phenotypic quality or condition to …
