I keep rediscovering the same thing: no matter what you see in the “bird book” or online, birds, even of the same species or from the same nest don’t look quite the same. The last Blue Jay I drew had a big black face, but this one only had a small black patch around each eye and a lot less black striping in his wings. Some Blue Jays are a brighter blue. Others are closer to gray-blue. They are as unique in their own way as we are in ours.
The males and females look the same, as do the young ones who are miniatures of their parents. Some are much bluer than others. I enjoy their company. They are funny and lively.
