You have to tame a pego by letting it steal berries from you but to tame the flying pego, you need to knock it out. THEY ARE BASICLY THE SAME ANIMAL! WHY CANT YOU TAME THE FLYING PEGO LIKE A NORMAL PEGO, IT DOES NOT MAKE SENSE!!!
Similarly to real life, these greedy douchebags will try to steal your sandwiches, however if you are drunk enough, you can stay up into the late hours of the evening and have deep insightful conversations with these feathered friends as they simply stare at you in confusion and bark in bird language. In return they will bring you magical fish as a reward.
You have to tame a high level because it would have so little health you would kill it by accident. I would use a long neck to knock it out and probably 10 bolas because they are pretty hard to hit. Up if this helped.
They need to make it so that if you put narcos bio toxin etc in ur last hot bar a lot the icthyornis will eat them and get knocked out(like putting berries in ur last hotbar slot to tame the pego, but instead of taming it will be knocked out)
