If you miss all your bolas picking up the eggs won’t help they fly in circles when attacking to get keratin if your scared of bugs like me slaughter carbon Emmy’s with raptors then pounce attack that gets more keratin from my experience hope this helps
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!
