Ever need lots of raw fish. Easy! Instead of swimming around in the water risking getting attacked by megapiranhas, simply make a saddle for your Pelagornis, Ride it into the water, and it one shots every small fish.
Occasionally one will fly away from the sea and onto a hill. But rarely. Try to wind up a bola and throw it at one when it is directly above your raft hit it with a club is ok or tranqs are better. Note: they don’t eat meat but they can eat fish meat and need a few narcotics to tame.
I had a good one of these things and I named it Terrorgornis. I used it to find places I have yet to discover. But after I went to the desert, I got off it and it swam away chased by sharks. Is this normal!?!
You can tame it on primitive plus but you need to make the kibble in a cooking pot. It won't work if you make it in a cauldron. Hopefully that's helpful to those that are trying to make kibble but cannot.
