The COVID-19 pandemic resulted in extraordinary declines in human mobility, which, in turn, may affect wildlife. Using records of more than 4.3 million birds observed by volunteers from March to May 2017–2020 across Canada and the United States, we found that counts of 66 (80%) of 82 focal bird species changed in pandemic-altered areas, usually increasing in comparison to prepandemic abundances in urban habitat, near major roads and airports, and in counties where lockdowns were more pronounced or occurred at the same time as peak bird migration. Our results indicate that human activity affects many of North America’s birds and suggest that we could make urban spaces more attractive to birds by reducing traffic and mitigating the disturbance from human transportation after we emerge from the pandemic.

COVID-19 期间人类活动减少改变了整个北美的鸟类土地利用

COVID-19 大流行导致人类流动性显着下降，进而可能影响野生动物。利用志愿者在 2017 年 3 月至 2020 年 5 月期间在加拿大和美国观察到的超过 430 万只鸟类的记录，我们发现在大流行改变的地区，82 种重点鸟类中有 66 种（80%）发生了变化，通常在与大流行前城市栖息地、主要道路和机场附近以及封锁更为明显或与鸟类迁徙高峰同时发生的县的丰度相比。我们的研究结果表明，人类活动影响了北美的许多鸟类，并表明我们可以在我们摆脱大流行后通过减少交通和减轻人类交通的干扰来使城市空间对鸟类更具吸引力。
