Tame a tapejera and then sit on one of the passenger seats and whistle it up( need to be flying off the ground). Find the queztal once you get next to it whistle passive and continue this process until you knock it out! Good luck taming!!!
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 manage to knock a quetzal out, try starve taming. If you never tried starve taming it’s just leaving a Dino’s hunger go to half way or lower and then you start feeding. I’ve done this many times and it’s very useful taming trick.
