蜜蜂觅食沟通的方向和距离的食物来源和新的巢址巢伴侣通过一种象征性的舞蹈语言。有趣的是，舞者传递方向信息的精确度与到广告食物源的距离呈负相关。“调谐误差”假说表明，殖民地受益于这种不精确性，因为它分散新兵在一个固定大小的补丁，而不管距离广告网站。另一种调谐误差假说是，舞者在身体上无法对附近的源进行非常精确的舞蹈。在这里，我们通过研究在相对较短的距离内随着觅食距离的增加而舞蹈精确度的变化，同时控制环境影响，重新审视了调谐误差假设。我们发现，蜜蜂确实增加了他们的舞蹈精度与觅食距离的增加。然而，我们也表明，舞蹈进行的蜂群侦察机附近（30英寸）的巢址，在那里可能没有好处的不精确性，要么没有或只有有限的方向信息。这一结果表明，舞蹈沟通的不精确性主要是由身体限制造成的，当广告网站就在附近时，舞者转身的能力不够快。
Honey bee foragers communicate the direction and distance of both food sources and new nest sites to nest mates by means of a symbolic dance language. Interestingly, the precision by which dancers transfer directional information is negatively correlated with the distance to the advertised food source. The 'tuned-error' hypothesis suggests that colonies benefit from this imprecision as it spreads recruits out over a patch of constant size irrespective of the distance to the advertised site. An alternative to the tuned-error hypothesis is that dancers are physically incapable of dancing with great precision for nearby sources. Here we revisit the tuned-error hypothesis by studying the change in dance precision with increasing foraging distance over relatively short distances while controlling for environmental influences. We show that bees indeed increase their dance precision with the increase in foraging distance. However, we also show that dances performed by swarm-scouts for a nearby (30 in) nest site, where there could be no benefit to imprecision, are either without or with only limited directional information. This result suggests that imprecision in dance communication is caused primarily by physical constraints in the ability of dancers to turn around quickly enough when the advertised site is nearby.
