Bird Eggs

The coloration of wild birds’ eggs is for protective purposes.  Eggs often blend in with the colors around the nest so any enemy cannot spot them easily.  Ground nesters, such as plovers and terns, nearly always lay spotted, dull-colored eggs.

These eggs are almost invisible against the ground on which they lie, while tree nesters often lay bluish or greenish eggs.  These are less visible in the uneven light in foliage.  Eggs laid in dark holes, such as those of the woodpecker, are pure white. Tucked out of sight, they have no need for camouflage. – Dick Rogers
