People say they are a difficult solo take but I just got myself one solo. Was on a griffin and kept shooting It down. What’s great about the griffin is that you can also live left and right. Just followed it around until it fell. Thankfully mine fell on a high mountain and it was ok. Super easy, just watch out because if it is going to drop in a dangerous spot....well there goes all ur trans darts
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.
To solo tame, grapple to an argentavis, and be ready to set your argentavis to passive and attack my target on command. Just maintain a process of having your argentavis chase the quetzal, when you get close enough set it passive, then fire a tranq dart/arrow. This is a long process, but it is by far the easiest way to solo tame, unless you already have a quetzal.
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. Upvote if you agree.
