Greater honeyguides (Indicator indicator) lead human honey-hunters to wild bees' nests, in a rare example of a mutualistic foraging partnership between humans and free-living wild animals. We show experimentally that a specialized vocal sound made by Mozambican honey-hunters seeking bees' nests elicits elevated cooperative behavior from honeyguides. The production of this sound increased the probability of being guided by a honeyguide from about 33 to 66% and the overall probability of thus finding a bees' nest from 17 to 54%, as compared with other animal or human sounds of similar amplitude. These results provide experimental evidence that a wild animal in a natural setting responds adaptively to a human signal of cooperation.
大拟啄木鸟（Indicator indicator）引导人类猎蜜者找到野生蜜蜂的巢穴，这是人类与自由生活的野生动物之间互惠觅食伙伴关系的一个罕见例子。我们通过实验表明，莫桑比克猎蜜者寻找蜂巢时发出的一种特殊叫声会引起蜜导鸟的合作行为增加。与其他类似幅度的动物或人类声音相比，这种声音的发出使被蜜导鸟引导的概率从约 33%增加到 66%，而总体上找到蜂巢的概率从 17%增加到 54%。这些结果提供了实验证据，证明在自然环境中，野生动物会对人类合作的信号做出适应性反应。
