Imagine you're a bee. Buzz, buzz, you're looking for flowers. Good for you. Now, as you might imagine, there are competing bees afoot--naturally you're not the only species looking for pollen and nectar. Let's say you've found a nice cluster of flowers, a good source of food. You might imagine that with competing bees--eavesdroppers--around, it is best to communicate quietly. In many cases, you would be right. But that's not always true. Sometimes it is best to conspicuously communicate the location of a food source to your friends, eavesdroppers be damned!
