Some of the most attractive birds seen in North America fall into this category, such as the bluebird and the bunting families. The male Eastern Bluebird, the Indigo or Lazuli Buntings are examples of beautiful looking Blue Birds.
Blue and green are created by pigments known as the biliverdin and the zinc chelates. According to the North American Bluebird Society, in 5-9% of reported nest observations, bluebirds laid clutches in which the eggs were a uniform, lighter color â white, pale pink or pale blue. It was once believed that laying white eggs was a genetic trait â like blue eyes and brown eyes in humans.
