Ravens Harassing Bobcat-Part I

Tonight at dusk while watching a family of Common Ravens I have been following for the past 2 weeks, I saw the parents fly from past the safe rock ledge where they had brought the fledglings to spend the night to a tree several hundred feet away while calling repeatedly. They seemed to be directing their attention to something I could not see, then out walked a bobcat. Apparently these very protective raven parents saw this bobcat from hundreds of yards away and flew in to harass it into leaving the area. These raven parents clearly will not allow a threat anywhere near their fledglings (at least the two I could see) which were safely deposited on a ledge several hundred feet from where they began harassing the bobcat.
