These are easy without a tent. I've tamed a few dozen on Ragnarok at Viking Bay. Feed them and track it; they don't seem to wander to far. I've gotten to where I can track four at a time.
I just remove everything from my inventory except the spoiled meat and start feeding and running after them. If you time it right you can feed them before they land/take off and run to another one. They touch down twice before landing and leave a cloud of dust every take-off/landing.
Also, they can get into a regular doorway pretty easily. I learned that the hard way running for my life.
