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 …

Birds are the only living amniotes with coloured eggs,,–, which have long been considered
to be an avian innovation,. A recent study has demonstrated the presence of both red-brown …

Coevolutionary arms races are a powerful force driving evolution, adaptation, and
diversification. They can generate phenotypic polymorphisms that render it harder for a …

Arms races between avian brood parasites and their hosts often result in parasitic mimicry of
host eggs, to evade rejection. Once egg mimicry has evolved, host defences could escalate …

Current research into the evolution and adaptive function of avian eggshell pigmentation,
including maculation, has focused mostly on signalling‐based and structural function …

The avian embryo's development is influenced by both the amount and the wavelength of
the light that passes through the eggshell. Commercial poultry breeders use light of specific …

The vibrant colors of many birds' eggs, particularly those that are blue to blue-green, are
extraordinary in that they are striking traits present in hundreds of species that have …

Avian eggs are at risk of microbial infection prior to and during incubation. A large number of
defence mechanisms have evolved in response to the severe costs imposed by these …

The colourful appearance of bird eggshells has long fascinated biologists and considerable
research effort has focused on the structure and biochemistry of the avian eggshell matrix …
