What is the bird Phoenix?

A phoenix is a legendary bird that sets itself on fire and rebirth from its ashes. Some people believe that there can only be one phoenix at a time. It looks like a bird on fire.

It is a fantastic creature from the Ancient Greek Mythology. It is a symbol of rebirth, reconstruction, of perpetual renewal. It never dies; when it is getting to old, it sets itself on fire and gets reborn as a "chick".
