I often find them in a groups of two on Craggs island
Quetzal
The Quetzal is a giant pterosaur and powerful aerial hauler. Its platform saddle can serve as a mobile base for transport and field operations.

How ARK players tame and knock out the Quetzal: what to feed it, what to knock it out with, and how to keep it safe.
If you have a griffin before quetz,sit on your griffin and just follow the quetz,knock out the quetz with tranq darts,and then do starve taming,thats how I tamed our quetzal,it was actually pretty chill for my first time taming it.
