Eastern Bluebird (Juvenile male)

This juvenile male has more brown on the neck than the other females, and less body blue than the other males. In the picture where it's flying, there is more blue on the tail/back than the females usually. I think he might actually be a juvenile male, or just be changing feather color a bit from the winter and be a female? Not really sure. There is another little bird in the picture on the left side. I'll work on that ID.
