该课题组收集了1万多个社区观察结果，并对近10万次发声进行了人工智能分析，发现鸟类的行为在很大程度上受到了这几分钟意想不到的下午黑暗的影响。超过一半的野生鸟类改变了它们的生物节律，许多在日食之后会发出黎明的合唱。这个自然实验强调了光在塑造动物行为方面的力量：即使“夜晚”持续不到4分钟，它们的行为也会随之发生变化。
据悉，2024年4月8日，一次日全食打乱了北美鸟类春季繁殖前的明暗周期。

Abstract: On 8 April 2024, a total solar eclipse disrupted light-dark cycles for North American birds during the lead-up to spring reproduction. Compiling more than 10,000 community observations and artificial intelligence analyses of nearly 100,000 vocalizations, we found that bird behavior was substantially affected by these few minutes of unexpected afternoon darkness. More than half of wild bird species changed their biological rhythms, with many producing a dawn chorus in the aftermath of the eclipse. This natural experiment underscores the power of light in structuring animal behavior: Even when “night” lasts for just 4 minutes, robust behavioral changes ensue.
