For benjamin1: the blue color of robins’ eggs comes from a pigment called biliverdin. This pigment is made the female robin. Female robins with higher levels of this pigment produce more brightly colored eggs. In turn, male robins seem to take better care of newly-hatched birds born from brightly colored eggs.
