If you don't have argentavis tame now.it is easy to tame but don't do mistake like me.iam going south zone to North zone for tame and when I was reached north i see one mountain and that mountain have so many argy when I hit one with tranquiliser arrow so he get to me and hit me so my pteranodon goes for a fight and kill argy next day I found a beutiful argy and I tame it. One advise when you go to tame argy don't set your dino at passive because if you set on passive your dino will kill argy like me
