斑胸草雀从视频演示中学习觅食的社会信息。直播对观众行为的影响与现场演示相同。无声视频对观察者行为的影响与现场演示相同。观察人士没有用声音复制这段视频。当有一只雄性诱饵出现时，观察者不会模仿。从经验丰富的演示者到naïve观察者的信息传递通常取决于演示者的特征，如熟悉度、成功或支配地位。演示者是否注意和/或与观察者互动也会影响观察者对社会信息的获取或使用。在这里，我们首先使用视频演示范例来测试视频演示是否与在斑胸草雀中使用现场演示具有相同的效果，其次，测试演示者和观察者之间的视觉和声音交互对观察者使用社会信息的重要性。我们发现，雌性斑胸草雀会模仿它们在直播视频中看到的雄性示威者的新食物选择，而当它们在同一视频的回放中看到它们时，它们不会始终复制示威者的食物选择。尽管天真的观察者在没有声音的情况下复制了演示者的声音，因为他们从播放的视频中复制了声音，但女性并没有复制视频中提供的视觉信息与看不到的活的男性的声音信息不匹配的地方。综上所述，这些结果表明，视频演示是测试社会信息传递的一种有用的方法，至少在觅食环境中是这样，但更重要的是，社会信息的使用根据观察者和演示者之间的声音互动或缺乏声音互动而变化。
Zebra finches learn social information about foraging from video demonstrators. Live streaming has the same effect on observers’ behaviour as live demonstration. Silent video has the same effect on observers’ behaviour as live demonstration. Observers did not copy the video with sound. Observers did not copy when there was a decoy male present. The transmission of information from an experienced demonstrator to a naïve observer often depends on characteristics of the demonstrator, such as familiarity, success or dominance status. Whether or not the demonstrator pays attention to and/or interacts with the observer may also affect social information acquisition or use by the observer. Here we used a video-demonstrator paradigm first to test whether video demonstrators have the same effect as using live demonstrators in zebra finches, and second, to test the importance of visual and vocal interactions between the demonstrator and observer on social information use by the observer. We found that female zebra finches copied novel food choices of male demonstrators they saw via live-streaming video while they did not consistently copy from the demonstrators when they were seen in playbacks of the same videos. Although naive observers copied in the absence of vocalizations by the demonstrator, as they copied from playback of videos with the sound off, females did not copy where there was a mis-match between the visual information provided by the video and vocal information from a live male that was out of sight. Taken together these results suggest that video demonstration is a useful methodology for testing social information transfer, at least in a foraging context, but more importantly, that social information use varies according to the vocal interactions, or lack thereof, between the observer and the demonstrator.
