This was a picture of Wilbur from a few years ago.
This is Wilbur now . . well, last night.
He moved just as I took the picture but can you see that he’s lighter?
Rebecca (I think it was) commented that she didn’t know birds got gray so I googled it. I found that they technically do not get gray, but lose pigment in their feathers as they get older. Isn’t that kinda what happens to us? It’s actually very similar so . . call it what you like, Wilbur is getting older and lighter colored.
