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.)
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.
