Idk why everyone makes this so complicated with all the grappling stuff all you have to do is,

1. Get or use a tapejara that’s a low level with a couple levels into movement speed

2. Get a rifle or crossbow with either darts or tranqs

3. Find a quetzal and then go to the back of your tapejara and set to attack the quetzal

(Since quetzals have high health and ur using a low level tapejara you can actually leave the tapejara to attack the quetzal, it’ll be fine)

4. Knock It out, not over water, and put whatever you want into it and ban you have a quetzal

Btw, you don’t need to worry about the tapejara’s stamina, it doesn’t decrease while you sit in the back seat

Guys this is the ersieht was to tame a quetzal. All you need is a tapejara.

1) Whisle your Tapejara to follow you

2) Ride you Tapejara and surch for a quetzal

3) When you found a quetzal, go an the back of the Tapejara (dont forget that you have to make the follow whisle on Tapejara, otherwise the will Flyer to the ground)

4) Make the attack whisle while you are on the Tapejata's back, so your tapejara will follow the quetzal.

5) Just shoot the quetzal with tranq darts/arrow and make the passive whisle on the Tapejara when he is too close to the Quetzal.

6) Repeat that till the quetzal gets knocked out and enjoy your quetzal taming.

TIPP: They spawn near the Obelisk and fly trought the whole map after spawning. GOOD LUCK!
