Lower lvl, 5-20 1,4 franks from the crossbow, with a bolla. Down for the count. I found cooking meat, not all at once, but batch by batch, tamed quickly. Kill n cook, the way to a Dino's heartstomach 😂
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!
