Recommended to use pteranodon or any other fast bird. Once you have spotted one, build a trap consisting of 4 gates in a line with small gaps so the snow owl can’t fly out. Place one door on the side that is farther away from the bird and leave to other one open. Then take your bird and agro the bird by flying close to it or shooting it. Once it is near the trap dismount and punch it so it attacks you and not the bird. You also wanna make sure your bird is passive for this. Then lure it into the trap and once it’s in put the door on and tranq it. You could then feed it the recommended food and once it done taming you have a snow owl.
