Well, usually sheep don't look frightening - but those did when I climbed those slopes. It wouldn't be funny up there on a steep slope if those horns were to connect with your body.
Okay, those aren't the sheep as most people know them; they're wild sheep, or mufflons. They aren't "wild" here of course, as there shouldn't be any real wild sheep in Austria anymore, but they're used for those steep slopes as our domestic sheep don't like to climb slopes like that regularly.
