LTS: "...much more acrobatic ..." Obvoiusly, you've never seen them in action. I've had them hover about a foot in front of me (perhaps looking at their reflection in my sunglasses) and just that is impressive. When they start fighting it's amazing. Your eyes can barely follow them. And, watching them beat up on a cat is unreal. A pair will fly in figure eights at right angles and, when the cat is distracted by one, the other will peck the cat on the top of the head. I watched one of my cats hug the ground under such an attack for about two minutes before making a run for it. She licked a bunch of blood off her paw that day. And she avoided that lilac bush for the rest of the summer.
