EASIEST WAY TO TAME AT ANY LEVEL:
Stock up on trans, 4 - 5 per bird, wait for it to land, walk an aim-able distance away, FIRE AWAY, when it comes close, run towards it while flanking from the side and from behind as it passes, you WILL take a foot or two, so be prepared to have SOME food handy for yourself.
They stay tranqed for a little over 30 minutes. Use that time to starve them whil you hunt some predator or big game to get some prime and VOILA!
I solo play and just tamed 5 Argen in one go. I am going to paint them blue and call them The Blue Angles. 😉
Lure an argie into an enclosure where it cant escape and you can ko it or tranq the argie till the argie starts running away then pull up with a moth and fart on it and then its basically stuck for 30 seconds, easy ko
