Current research into the evolution and adaptive function of avian eggshell pigmentation, including maculation, has focused mostly on signalling‐based and structural function …
There is huge diversity in visual systems and color discrimination abilities, thought to stem from an animal's ecology and life history. Many primate species maintain a polymorphism in …
Many birds lay eggs speckled with black or reddish-brown spots of protoporphyrin pigment, but the function of these spots is debated. Two recent hypotheses have received …
While one has evolved and the other been consciously created, animal and military camouflage are expected to show many similar design principles. Using a unique database …
The outer layer of the eggshell in birds is in many cases covered by pigments that are assumed to be genetically determined traits with a negligible environmental component. To …
Many animals use structural coloration to create bright and conspicuous visual signals. Selection of the size and shape of the optical structures animals use defines both the colour …

Avian eggshell color seems to fulfill multiple functions, some of them being structural and others signaling. In this study, we tested whether or not eggshell coloration may play a role …
The diversity of eggshell colours and patterning across different birds is a fascinating example of the extended avian phenotype. The avian egg's background colours range from …
Numerous animals rely on camouflage for defence. Substantial past work has identified the presence of multiple strategies for concealment, and tested the mechanisms underpinning …
