These things spawn in abundance in Crystal Isles. If you're looking for a good one, I suggest you go there.

Best solo method that I've found, by far, is to use a Archaeopteryx with a Tapejara. Once you find a Quetz, jump off and switch to front passenger. Whistle attack while shooting tranqs, then whistle passive once you get too close. I bring Argies and set target and follow distance both to high, make them follow the Tapejara. When you eventually knock the Quetz, whistle the Argies to follow you to defend it wherever it lands. Make sure all the Argies are set to "Only attack conscious".

Any taming food or kibble I bring, I place in the Tapejara and have them set to passive when I land. Once you knock a Quetz out of the sky, you can use crouch to go straight down with the Tapejara so you don't lose where the Quetz lands.

If you are on crystal isles and you want a quetz the easiest way to knock it out is with a griffin because you can use weapons on it and you still have full control

If you're on a cluster bring a snow owl and freeze it mid air and just surround the quetz with gates

Easy af if you have a tribe mate and tapejara just fly up to the quetz and let your probe just tranq is out make sure it’s not over water obviously

Get urself a griffin....tranq the quetz from the back of the griffin....raw mutton works best if you don't have kibble...tada...quetz

If you with tribe mates just get either argy or pteranodon pick up your tribe mate and the tribemate who has been picked up just start tranqin out with any tranq ammo worked for me and now I have 2 high lv quetzals 🙂

Screw flyers nerf, I'm just gonna boost the hell out of a proctodon

Knock out is too easy now that we have the net gun..

All you gotta do it bet it and shoot it’s eye wile it’s down it’ll do like 5-6x the amount of torpor then when it gets out of net just chase it for a bit and keep shooting till it knocks if your using a low tier weapon for tranqing you might need to net it again it used to be you had to chase em and try to bulls eye it’s eye to get the extra torpor but now the net gun makes it to easy you could also just trap it with some Dino gates and if you’ve got a tribe you could all shoot it wile it’s netted and knock it out real quick but careful not to shoot it once it’s out

Use a griffin and just keep pelting it with tranq darts. Once you're out of stamina, switch to the passenger seat (have the griffin on follow) and switch back to your main one once the stamina is full!

Get Griffin

Hold longneck with darts

Find Quetzal

Shoot Quetzal

Feed Quetzal

To tame use a tapejara and use the chair button then shoot the Quatzal then let him run and once he unloads fly to him and he won’t be running away and just keep doing that and you will knock him or her out, they need a LOT of narcotics, hundreds really, and you can search for prime but leave the tapejara and put him on neutral so it can protect the quatzal, the quatzal is also nicknamed “lord of the skies” because he is the only flying Dino that can hold a platform saddle on the island map.

If you see a a lvl 10 or 20, and if you are only on 40 lvl with pterenedon and parachutes, jumb right above quetzal and hit at least 2 arrows each time. It will be k.o. in 10 to 20 arrows for real.

Or you can level up and use grappling hook. Take a pterenedon with low attack and high stamina, put some Wight on pterenedon to make it's speed same as quetzal. (Test it before flying by calling via whistle). Go above quetzal , open parachute and use grappling hook. Set the quetzal as target and you can change arrows to tranq and k.o. quetzal.

Keep your weight low only keep kibbles bio and tranq arrow in inventory and maybe some spikes in pterenedon because it may be slow when it is carrying you but once you choose quetzal as a target it will run neglacting your weight.

It's easier with a tippy or 2 players and another quetzal

In extinction get a snow owl and ice bomb the quetzals back ,it will freeze and fall to the ground then place some stone dinosaur gates and that’s a trapped quetzal

When knocking out a 150, use 80 tranq darts for a regular longneck rifle. Feeding gives 3.4 (No Balm) with prime meat. I didn't look at the time though.

Use a tapejara and have a teammate. Have you or the teammate sit in the front passenger seat while the other person fires tranq arrows or tranq darts

The best way to tame this big boi is with a griffin, whilst e ridding, shoot the mofo.

To tame make sure u have heck ton of ancient amber kill it get implant make red ob trap ressurect boom easy tame

When taming a quetz solo, without quetz, the best way is to guide it towards mountains and get it stuck, sometimes doesnt work though and you have ti deal with the wildlife
