In learning a bit more about why the eggs are blue I read in Science Daily that "The blue colour in robin eggs is due to biliverdin, a pigment deposited on the eggshell when the female lays the eggs. There is some evidence that higher biliverdin levels indicate a healthier female and brighter blue eggs. Eggs laid by a healthier female seemed to encourage males to take more interest in their young."
Hopefully everyone will realize that I mean no harm and that my presence doesn't distract the males from noticing the gorgeous color of these eggs!
