If you have an Argentavis then just pick it up and drop that lil’ doggy in the taming pen and make love to it with your tranq arrows. If you don’t have an Argentavis then use bolas or bear traps for ez KO. Although be careful because there is ALWAYS more than one! - Gabriel
These things are great scouts and have amazing damage for their size. Be careful when taming. Try to trap them so they cant hit you or escape when taming. Always make sure you have stamina on them as they dont move fast when winded.
