First time seeing one ever:
Aww it's so cute and fluffy, it's just sleeping... Oh wait, what's it doing. It's waking up? Uhh, why are it's eyes-. OH MY GOD, HELP, THIS THING IS NOT CUTE, ITS A BLOODTHIRSTY KILLER DEAR GOD!!!

Whoever tames one of these with punching,and cooked fish meat, is a real man.

So yea I was in the cliffs enjoying the peaceful views and watching my ankly to be tame. The night settled in so as standard standing torch was at the ready. All of a sudden I hear my argentavis screeching turns round to see this son of a bitch holding the bird in its mouth and shaking me to my core. As always I tried to remain calm when ark is just arking with you. Equipped my sword light disappears and I'm frantically slashing and hacking one of these buggers. Eventually the beast drops my bird has a slither of health and a sabertooth bitch slaps my argy. R.I.P sir flattery

While it's asleep, draw a mustache on its face and run for life :D
