I recommend taming up one of these. A high level one is really fast for flying.
All you need is a bola and a bow.
Bola the flying reptile, and shoot it until its unconscious.
When it does, I recommend giving it Raw Prime Meat.
Then just wait untill it's tamed. Remember to give it
narcotics, or it'll wake up!
When knocking pteranodons out, be sure to have a bola, it doesn't take many tranq arrows to knock it out. Once it is down, put spike walls up around it (with a little space so you can go in and out) so it doesn't lose taming efficiency or die.
To kill pretty much anything on these birds, tame a high level, then pump stam to 3k, then the remainder in melee. Barrel roll into alphas etc. But keep eye on Stam. Never regen Stan on ground, know your ledges!
