When it lands bola it so it can’t fly off. Use tranq darts because arrows may kill it, but a club works for low level birds. Very slow tame with raw fish, so either make pego kibble or use prime fish, which can be gathered from a saber tooth salmon with a sickle. If you can’t get one to land, you can try to shoot it midair with the darts or the bola, but they move in odd patterns sometimes, and may fall in the water. If you kill all the fish near it it will decide to land. After you get your first, prime fish will come easy for the higher level ones.
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.
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.
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)
