If you want to tame one set a tamed Tapejara to follow you but you have to be off your tame first then find change seats a quetzal set it to attack the quetzal and shoot some tranqs and you can set your Tapejara to follow you when you are of it and when you fly it it will stay in the air so it is a easy way to kill alpha’s.
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
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.
