A GUIDE TO AGING BALD EAGLES

So very curious about the Bald Eagle that I photographed last week, a quick google search led to some very handy images and websites. I’m still not sure exactly how old is the one that I have been seeing but after searching, I’d say it was three and half years old. Bald Eagles don’t gain their pure white heads and tails, intensely yellow eyes, and overall dark brown plumage until they are five years old.

A side note- You can’t tell the difference between male and female unless side by side; the females are slightly larger.

These were the most helpful websites for aging Bald Eagles:

How to Age and Identify a Juvenile and Sub-Adult Bald Eagle

Several years ago, a juvenile Bald Eagle was at Niles Pond. After looking through the images, I would think it was a Basic II Plumage, about two and half years old, when the photos were taken.
