Also gryphon, griffon.

Mythical creature with the head, beak, wings, front legs, and front talons of an eagle and the body, hind legs, and tail of a lion.

Fiercely territorial, only mated pairs are typically found sharing their range (and pairs stay mated until the death of one. They are fiercely committed creatures, and many do not ever take a second mate). They are fierce beasts when angered, but loyal, peaceful and deeply deeply wise animals.
