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.
Put ramps and some ceilings on a raft. Wait for it to stop on the water and start paddling around. Drive he raft directly towards it while it's facing u. Scoop it up and trank it. You have to remember not to move the raft once it's unconscious or it will slide off ðŸ‘
If you can get the bird on the water near a raft, (it doesn’t matter what kind) the birds swim in circles, and can climb up on your boat. Bola it and knock it out, and then you can drive out to sea to catch prime fish and not loose your tame! (Recommended: put a preserving bin on your boat. You can store the meat in in and use it when the bird is hungry enough.)
Was taming a 150 while also gaming a 150 megladon. Thought I had enough narcos for the bird while I went to get a saddle. When I came back it was gone. Lesson learned, no double tame because this bird takes a long time and needs several narcos. Also use prime fish if you have it.
