Wait for one to land, and throw a bola at it. It should go down in 1-3 tranq arrows if it’s not a high level. If you don’t have tranq arrows you might be able to hit it with a club if it doesn’t get out of the bola. Shouldn’t need more than 20 meat but you will need a lot of narco berries. Around 50 were used for my level 48
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!
