Congratulations Gina! Your spotting has been chosen for Project Noah Fact of the Day: "Egg hunts and the decoration of eggs are popular Easter traditions. Some eggs are in no need of painting though! Check out the blue eggs of the American robin. The striking blue color of robins’ eggs comes from a pigment called biliverdin. This pigment is produced from a shell gland and is thought to be an indicator of female fitness. Female robins with higher levels of biliverdin produce more brightly colored eggs. In turn, male robins have been shown to take better care of newly-hatched birds born from brightly colored eggs. This suggests that males use egg color as an indication of the healthiness of their mate.
