SINGLE PLAYER TAMING - Grab a high level Argy with high stamina and a lot of grappling hooks, use your spyglass to look at the quetz and press attack, until you get close. When you get near the quetz, press U to stop it attacking, jump off your bird and shoot it with the grappling hook, make your bird attack the quetz, then switch to a second Xbow or long rifle with tranqs, aim for the head when you get close, and if your argy gets too close, simply press U! Rinse and repeat, it may take some time to get used to doing the grappling hook to the argue, but after that, it's easy! Good luck, happy taming!!
1) Get a good Argy
2) Find a quetz
3) Jump off the Argy and shoot it with a grappling hook
4) use the spyglass to attack the Quetzal
5) when you get close, press U to stop the Argy hurting the Quetz
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.
