The signal detection problem of aposematic prey revisited: integrating prior social and personal experience

Data collected during three separate experiments using the \"novel world\" (Alatalo & Mappes, Nature 1996) approach to test how social information changes predator discrimination of novel aposematic prey from a cryptic palatable alternative. Experiments were conducted with great tits (Parus major), captured from the wild and released afterwards, at the University of Jyväskylä Research Station, Konnevesi, Finland (62.6° N, 26.3° E) during three winters (2013-2014, 2016-2017, 2017-2018). Social information was provided by video playback of a demonstrator (adult male) showing an aversive behavioural response to a novel prey signal before observers (juveniles, adults, males, females) searched for prey signals against a background in either an aviary or in a \"miniature novel world\" in an experimental holding box.本数据集采集自三项独立实验，实验采用“新奇世界（novel world）”范式（Alatalo & Mappes, 《Nature》 1996），旨在探究社会信息如何改变捕食者对新奇警戒色猎物与隐蔽可口对照猎物的辨别能力。实验以大山雀（Parus major）为受试动物，所有个体均从野外捕获，实验结束后放归原地；实验场地位于芬兰孔内韦西于韦斯屈莱大学研究站（北纬62.6°，东经26.3°），实验时段涵盖三个冬季：2013-2014年、2016-2017年及2017-2018年。实验所使用的社会信息由演示者（成年雄性个体）的视频回放提供：演示者会先对新奇猎物信号表现出厌恶行为反应，随后观察者（包括幼鸟、成鸟、雄性及雌性个体）将在两种场景下搜寻猎物信号——分别为大型鸟舍，或是实验饲养箱内的“微型新奇世界”背景环境。
