The most scared I have ever been was about five or so years back I was deer hunting in west texas it was one of those cold days but the sun was warm I was half asleep and an 6" tall barn owl flew into the stand with me we fought to a draw after a couple of minutes and i backed out of the tower blind and let him have it. Yes you guessed it I was the loser a 280lbs man got whooped by a 6" tall barn owl
The sound a owl or any other bird of prey makes when they are trying to scare something is no joke. It will send tingles up your spine like nothing else will. Luckily my sister does wild animal rehab (tree hugger) but I went over and she had an owl in a dog carrier with something broke. But when you got near it would do a screeching hiss sound! But I learned that means they are scared if not they attack real quite. But it will scare the poop out of the biggest man!
