Alerion is a heraldic and mythological bird traditionally depicted as a disarmed eagle. Originally used as a heraldic term for a mature or young eaglet, it later evolved into a symbol with unique visual features such as a bulb-shaped head and an abstract winged oval representation. In medieval bestiaries, it is noted for its rarity and an unusual reproductive cycle, laying eggs every 60 years followed by the parents drowning themselves.
