Robin Egg Blue

There is nothing so lovely as a robin egg - seen here in our kolkwitzia (beauty bush) by the front of the house. It may not have been the best place to make this nest though, as it is right near the hose spicket, and every time I turn the water on, the robin screeches and flies off in a panic. Luckily it has been wet enough, I haven't had to water much.

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!
