I was delighted to learn that crows have a long longevity. I have one famil that comes to my feeder on a regular basis and brings its young to it every spring. The one crow has developed a dime sized white spot on it'a
right wing. I did not know that the babies have blue eyes. So pleased to learn about the leg bands. I have photographs of several birds with various leg bands and wondered about them. One had 3 leg bands. Thank you for the information.
