This is a very good point, but what alternative line in the sand do you draw? I would personally set the bar pretty high to showing purposeful control of behavior that is not the direct result of an evolved organism or species survival instinct, i.e., eating, fighting, fleeing, and mating doesn't count. Resourceful looking for food could count, as could certain camouflage maneuvers during flight, or multi-member hunting and defense, and all tool use. Definitely deception to win mates
