蝙蝠学习新的声音猎物线索一样快，从异种。向他人学习可以使个人迅速适应环境变化。虽然同种往往是可靠的模型，具有类似的资源需求的异种可能是合适的替代品时，同种很少或不熟悉最近的变化，资源的可用性。我们测试是否Trachops dangersus，拾荒蝙蝠，本地化的猎物使用他们的交配电话，可以了解新的猎物同种和同域蝙蝠Lophostoma silviculum。具体来说，我们比较了幼稚T。通过试错或社会促进，从受过训练的同种或异种个体中学习不熟悉的音调。T.这一新奇的线索是从L.像从同种种中一样迅速地从森林中消失。这是蝙蝠对一种新的声音线索进行社会学习的第一次证明，并表明异源学习可能发生在自然界中。我们建议，基于集群的社会学习可能有助于蝙蝠了解不熟悉的猎物，并促进其适应性辐射。
Bats learn about novel acoustic prey cues as quickly from heterospecifics as from conspecifics. Learning from others allows individuals to adapt rapidly to environmental change. Although conspecifics tend to be reliable models, heterospecifics with similar resource requirements may be suitable surrogates when conspecifics are few or unfamiliar with recent changes in resource availability. We tested whether Trachops cirrhosus, a gleaning bat that localizes prey using their mating calls, can learn about novel prey from conspecifics and the sympatric bat Lophostoma silvicolum. Specifically, we compared the rate for naïve T. cirrhosus to learn an unfamiliar tone from either a trained conspecific or heterospecific alone through trial and error or through social facilitation. T. cirrhosus learned this novel cue from L. silvicolum as quickly as from conspecifics. This is the first demonstration of social learning of a novel acoustic cue in bats and suggests that heterospecific learning may occur in nature. We propose that auditory-based social learning may help bats learn about unfamiliar prey and facilitate their adaptive radiation.
