Find your target get atleast 2 bolas and throw it at him on land not water make sure you have tranq arrow or if you get lucky you can knock it out with your fists and throw fish meat prime fish meat any meat will work kibble too keep narcotics with you just Incase or narcoberries to keep it knocked out
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!
