So there's a couple breeds that have blue eggs, and you can buy them at Whole Foods, actually.

Daniel Hanley, an evolutionary ecologist at Long Island University,

who has a very specific reason for caring about the color of his eggs.

I'm always thinking about eggs. It's one of the tools that I used to understand ecological and evolutionary processes.

So I study the function and evolution of natural colors, and the main system I use are birds' eggs.

Unlike white supermarket eggs, most bird eggs are colored various shades of bluish green or brown,

due to two characteristic pigments birds produce. And by examining the egg colors of 634 species

from around the world, Hanley and his colleagues found a curious pattern.

and those colors should give some type of adaptive benefit for those parents to be off of their

eggs for a slightly longer period of time.
