While they have multiple use as defenders and attackers and even use them to kamikaze to your target, you can also use them to hold your stuff. like food, narcotics, GPS, Bullets, tools, etc... That way a Pegomastax will never steel it from you. And if you carry a high level one (Recomended) they will shred noobs if they ever knock you silly. Just remember to always have them on follow before you put them on your shoulder (pick up) so that way they can't bait them. Also breeding them will make you have an army of flying birds that can even take down Rexs. Hit up-vote so people will know!
It you put them on aggressive and perch em on your shoulder, they warn you of any danger with a scream. Usually it’s a diplo or a compy. If it weren’t for my dimo I would’ve died hundreds of times, he once yelled so I left and the next day i went back and say a giga killing a pack of raptors.
I tamed a lvl 15 female one and named it Nova and she was really good. She killed a whole pack of lvl 20 carbonemys without taking any damage and I didn’t do anything except stand there and watch in shock and awe. This is a MUST tame for everyone who reads this. I was only lvl 10 at the time I tamed it and now I’m lvl 40 and this creature has never failed to impress me.
