Sounds about right. It reminds me of a story about a beehive where scientists placed food directly above the hive. Usually when a bee finds food, he goes back to the hive and does a figure 8 where he wiggles through the center pointing in the direction of the food. The bee accomplishes this by using the sun to navigate. The sun's ultraviolet rays penetrate the hive and it's visible to the bees inside. Well, when the food was straight up from the hive, the bee had no way of communicating this to the other bees, so it just danced around haphazardly.
