The colour of the tinamou’s eggs is due to the interplay between pigment coloration and what is known as nanostructure coloration. Eggs normally get their hue from a naturally-occurring chemical (pigment) that gives them a flat color. Underneath their iridescent coating, tinamou’s eggs are a regular old shade of blue.
Can birds lay different colored eggs?
Most cavity nesting birds lay all white eggs, whereas most other birds lay pigmented eggs. Another reason for pigmented eggs is to recognize parasitism via egg dumping by other bird species that have laid eggs into their nest in hopes that the host will raise their young.
Why are tinamou eggs shiny?
They determined that an extremely smooth cuticle produces the glossy appearance of tinamou eggshells. The cuticle is composed of calcium carbonate, calcium phosphate and, potentially, organic compounds such as proteins and pigments. This suggests that color comes from both iridescence and pigments.

Do any animals lay purple eggs?
No chickens lay colored eggs that are a true purple. Eggs have a protective layer on their outside called “the bloom,” which helps eggs stay fresh and bacteria free.
