To Tame find one that is alone and bola it then tranq the thing with arrows or club and just give it raw meat and go and repeat it to others and on your way back to base make the ones still alive follow you.
These things are OP! If you tame a high level one they make an amazing shoulder pet (surpassed only by ferox I would say). Mine does like 250 dmg a bite and it works well if you have an aviary of them. If this helps, please up!!
