Maybe too lazy to kill quetz and leave render? Go to red obelisk. Fly away, Tidy Save which removes all dinos out of render except tames. Then go to the sand area near red obelisk and wait for a quetzal to spawn. And thats how i tamed a 140 female quetzal, it was soo worth it! Also i realized that quetzals speed limit without ascendant creatures unlock is 200.0% By the way i tamed the 140 quetzal on a griffin with a journeyman crossbow with tranq arrows, it took over 100 arrows.

If you have any dodo arrows, make a trap (tutorials on YouTube) the shoot the quetzal with the dodo arrows. The quetzal will get triggered at you and lead it to the trap.

If you drop a quetzal due to knockout, and it lands next to a giga...just know, the quetzal belong to the giga. Now you get to watch your would be quetzal get eaten by a giga. Now you can go home and cry.

The fun way is to jump off and grapple to your argie and whistle it to attack and since argies are slow it won’t catch up in time so tranq till it goes out also bring parachutes and consider liking so more people will know
