为控制2019冠状病毒病（COVID-19）大流行而采取的行动显著减少了机动车交通，可能减轻依赖声音生存和繁殖的动物的听觉压力。在这里，通过比较最近全州范围内关闭之前和期间整个旧金山弗朗西斯科湾区的音景和歌曲，我们评估了一种常见的鸣禽是否响应地利用了新清空的声学空间。我们发现，在城市地区的噪音水平大大降低，在20世纪50年代中期的交通特征关闭。我们还表明，鸟类的反应是以较低的振幅产生更高性能的歌曲，有效地最大限度地提高通信距离和显着性。这些发现表明，行为特征可以迅速改变，以应对新的有利条件，这表明对长期存在的人为压力，如噪音污染的内在弹性。
Actions taken to control the coronavirus disease 2019 (COVID-19) pandemic have conspicuously reduced motor vehicle traffic, potentially alleviating auditory pressures on animals that rely on sound for survival and reproduction. Here, by comparing soundscapes and songs across the San Francisco Bay Area before and during the recent statewide shutdown, we evaluated whether a common songbird responsively exploited newly emptied acoustic space. We show that noise levels in urban areas were substantially lower during the shutdown, characteristic of traffic in the mid-1950s. We also show that birds responded by producing higher performance songs at lower amplitudes, effectively maximizing communication distance and salience. These findings illustrate that behavioral traits can change rapidly in response to newly favorable conditions, indicating an inherent resilience to long-standing anthropogenic pressures such as noise pollution.
