An interesting study published in Behavioral Ecology and Sociobiology, recently posted on sciencedaily.com, theorizes that the brightness of the color of robins eggs may determine the male robin's level of care for their young. The article noted that healthier female robins tend lay brighter pigmented eggs, which signals the likelihood of healthier offspring. Males were observed to feed hatchlings from brightly colored eggs more food.
Will I inadvertently skip over the white Whoppers Robin Eggs in search of a brightly colored egg when I eat them next year? I don't discriminate between chocolate covered malt balls.
