In my mind, there are few animals are majestic as bird of prey and among them the eagles are kings and queens. There are plenty of reasons why all sorts of eagle have been chosen in heraldry. The eagle with its keen eyes symbolized perspicacity, courage, strength and immortality, but is also considered "king of the skies" and messenger of the highest gods. Mythologically, it has been connected with Zeus/Jupiter and with Odin – the most powerful of the gods.
