The COVID-19 pandemic has changed life as we knew it just a few weeks ago. Millions of people worldwide are now under mandatory or voluntary lockdowns. All public attractions, including museums and aquariums, are shuttered, and the usually crowded streets of popular tourist destinations are desolate. An unanticipated silver lining during these challenging times for humans is that many of the Earth's other inhabitants are finally getting a chance to leave their normal habitats and roam freely.
