On April 8th 2024, a total solar eclipse disrupted light-dark cycles for North American birds during the lead-up to spring reproduction. Compiling over 10,000 community observations and AI analyses of nearly 100,000 vocalizations, we found that bird behavior was significantly 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 demonstrates the power of technology-enabled and public science projects to understand our natural world. Further, it underscores the power of light in structuring animal behavior: even when 'night' lasts for just four minutes, robust behavioral changes ensue.
2024年4月8日，一次日全食在北美鸟类春季繁殖前夕扰乱了它们的昼夜节律。通过汇总10000多次社区观测数据以及对近100000次鸟鸣进行人工智能分析，我们发现鸟类的行为受到这短短几分钟意外的午后黑暗的显著影响。超过一半的野生鸟类物种改变了它们的生物节律，许多鸟类在日食过后发出了黎明的歌声。这项自然实验展示了技术支持的公众科学项目对于理解我们的自然世界的力量。此外，它凸显了光照在塑造动物行为方面的力量：即使“夜晚”仅持续四分钟，也会引发显著的行为变化。
