Henderson says there are a couple of theories as to why this happens, but he believes the best one is the blue color is a way to distinguish robin eggs from other bird eggs. For example, cowbirds don’t make their own nests, so they lay their eggs in the nests of other birds.

So, when the mom and dad robins see the blue eggs rather than the cowbird’s speckled eggs, they know they are theirs to feed and protect.
