Smart bird

It seems that magpies understand mirrors:

Magpies can recognize themselves in a mirror, highlighting the mental skills of some birds and confounding the notion that self-awareness is the exclusive preserve of humans and a few higher mammals.

It had been thought only chimpanzees, dolphins and elephants shared the human ability to recognize their own bodies in a mirror.

But German scientists reported on Tuesday that magpies -- a species with a brain structure very different from mammals -- could also identify themselves.

Not smart enough to leave harmless humans walking under their nest alone, though.
