Magpie Recognizes Self

So does the magpie "think" or have a "mind"?

That's amazing, birds with personal identities. I think it suggests some rational faculty.
1.) Bird Moves in front of mirror
2.) Bird sees reflection
3.) Bird notices abnormality with sight(doubt it knows it's a sticker)
4.) Bird REACTS to abnormality.

I wouldn't say thoughts are EXACTLY reactions, but what would that be? A feeling is a reaction to stimuli right?, haha maybe the sticker made it's eyes hurt...idk what else it could be classified as besides a primitive thought process.

Yes, they also can identify abnormalities on others. They attract themselves by various colours, songs or behaviour. Is interresting which kind of species invented these characteristics.

Next to come, magpies get rights and their first order of business is to change their name since they find magpie to be derogatory. They would much rather prefer to be called Vanities.

Hahah touche Political Correctness, man's way of saying NO to nature.

It depends upon what you mean by those terms. But speaking loosely, the answer is obviously yes. You know it thinks and has a mind the same way you know other people think and have minds, by judging their behavior. Of course, by judging its behavior, you will probably come to the conclusion that the bird's mind is different from the average adult human mind, but that is a different issue.
