蜜蜂摇摆舞的一个奇怪的特点是对附近食物来源的方向指示不精确。关于这种不精确性的功能的一个假设是，它用于将新兵散布在某个区域，因此是对蜜蜂食物来源的典型空间配置的适应，即，大片大片的花朵。我们报告一个实验，测试这个调谐错误的假设。我们测量了摇摆舞广告的巢址（通常是一个树洞，因此目标，几乎是一个点）的方向指示的精度，并将其与广告的食物来源（通常是一个花补丁，因此目标，覆盖一个区域）的舞蹈。舞蹈的精度为附近的巢址显着高于舞蹈的等距馈线。用四个菌落证明了四次。因此，我们的证据支持的假设，在附近的食物来源的方向指示的精度水平被调整到其最佳值，而不是在其最大值。
A curious feature of the honeybee's waggle dance is the imprecision in the direction indication for nearby food sources. One hypothesis for the function of this imprecision is that it serves to spread recruits over a certain area and thus is an adaptation to the typical spatial configuration of the bees' food sources, i.e., flowers in sizable patches. We report an experiment that tests this tuned-error hypothesis. We measured the precision of direction indication in waggle dances advertising a nest site (typically a tree cavity, hence a target that is almost a point) and compared it with that of dances advertising a food source (typically a flower patch, hence a target that covers an area). The precision of dances for a nearby nest site was significantly higher than that of dances for an equidistant feeder. This was demonstrated four times with four colonies. Our evidence therefore supports the hypothesis that the level of precision in the direction indication for nearby food sources is tuned to its optimum without being at its maximum.
