If you find an injured owl:
Note your exact location so the owl can be released back where it came from. Contact a licensed wildlife rehabilitation specialist to get correct advice and immediate assistance.
Minimize stress for the owl. If you can catch it, toss a towel or sweater over it and get it in a cardboard box or pet carrier. It should have room to be comfortable but not so much it can panic and injure itself. If you can’t catch it, keep people and animals away until help can come.
Do not give food or water! If you feed them the wrong thing or give them water improperly, you can accidentally kill them. It can also cause problems if they require anesthesia once help arrives, complicating procedures and costing valuable time.
If it is a baby owl, and it looks safe and uninjured, leave it be. Time on the ground is part of their growing up. They can fly to some extent and climb trees. If animals or people are nearby, put it up on a branch so it’s safe. If it’s injured, follow the above advice.

This sneaky little lady has been living inside a Shoprite store in Thokoza for the last few weeks. She was a difficult customer, had all her hiding spots well mapped out, just in case some owl rescuers came knocking. That's Jacob in the photo, he's their security gent who offered a great deal of help in rescuing her. We don't often tag company rescues anymore, but we know Shoprite South Africa loves owls
Most animals will try to avoid fighting whenever possible. If they don't feel in danger, they will click their beak or puff up like a cat, but fighting is generally a last resort, as if they are hurt, they won't be able to hunt and won't survive. The risk is generally too high, so getting away is a much better option whenever possible. Once this guy is grabbed and sees the man isn't going to eat him, it's still unhappy, but it's not going to be as fearful.
I don't have any actual stats on bite strength, but owls' primary weapons are their feet. The feet are much more powerful and have those razor sharp talons. By securing the feet, he's taking away the biggest immediate danger to himself. It also minimizes the movement the owl can do, keeping it from hurting itself.
I just took a look at the burrito owl video again. It's mostly talons and just a bit of nibbling. :)
Thanks for the info.
I just made a new post for you that has a great foot attack.
