That’s just ridiculous thing I’ve had heard of. Just because your territory is to be defeated from rivals doesn’t mean you can own smaller prey that won’t satisfy your larger appetite. Besides Bibi and other caracals only hunt and devour smaller prey Leopards don’t care to hunt: Rabbits, smaller birds, rodents, bugs and small reptiles. And Africa didn’t catch that birdy. So it’s Bibi’s bird and right to eat.
