Stellars Jays (blue/blue gray with black heads) and Cardinals (males red females brownish) are very similar in appearance to Blue Jays.
One of Blue Jays adaptations are they have wings to fly in the sky. Another adaptation, is blur jays are blue, so they can camouflages in the sky so the animals that eat them, won't see the the blue jay.
Jays are larger, and have more white and gray coloration, and have a crest. They are in the family Corvidae, with crows and ravens. The bluebirds are a deeper blue, and are thrushes, family Turdidae.

All animals and birds go through this process. So yes, jays hit puberty.
Blue jays can be tame, but your best chance of taming one is raising it from the time it is a nestling/fledgling. I had a pet blue jay when I was a kid, but that's because I played mama for him when he was a baby and hand fed him.
