In the coastal Welsh town of Llandudno, usually timid mountain goats have ventured into the empty streets to take a look around. They've become an online favorite thanks to Twitter posts by video producer Andrew Stuart. "There's hardly anyone around to scare them or anything … they just don't really care and are eating whatever they can," he said. The UK has been on lockdown since March 23.

In Nara, Japan's first permanent capital, deer are considered "messengers of the gods" and have been designated national treasures. More than 1,000 regularly wander through the city's central park, and visitors are encouraged to feed them sugar-free wheat crackers. But with tourists staying away during the outbreak, some curious deer have been quietly investigating nearby shops and restaurants.

Thousands of macaques that roam the streets of Lopburi in Thailand haven't been so polite. Usually well-fed by tourists, the monkeys have been finding snacks hard to come by during the pandemic. They've even engaged in intertribal warfare over scraps, fighting in the streets and historic temples. Thailand, the first country outside China to confirm a COVID-19 case, saw 39 million tourists in 2019.

This young puma was recently found stalking through the empty streets of downtown Santiago, Chile, followed soon after by two more. The animals live in the nearby Andes Mountains and have increasingly been spotted in the locked down capital, home to about 6 million people. "There's no people, there's no noise, so they dare to explore a little more," said a regional official.

India, home to 1.3 billion people — around 17% of the world population — began its ongoing lockdown on March 24. Most flights have been suspended, and these stray dogs have taken advantage of the abandoned arrivals area at the Kolkata airport. There are tens of millions of strays roving the country's streets and slums; a law has made it illegal to kill or maim the animals.

Strays are also common in Istanbul — the city on the Bosporus has about 15 million inhabitants, but counts more than 200,000 free roaming cats and dogs. Local authorities regularly provide food and checkups for the animals, and that hasn't let up during the pandemic. Animal rights activists have said pets are increasingly being abandoned, amid false reports they can pass the virus on to humans.

Venice, usually a popular tourist destination, has seen dramatic changes during the outbreak which has brought Italy to near collapse. The northern city is normally swamped with visitors, but canals have emptied during the country's strict lockdown measures. Without the constant passage of boat taxis and gondolas the muddied waters have settled, and seabirds and fish are once again visible.

The United States, the new epicenter of the pandemic, has been gradually imposing varying degrees of lockdown measures across the country. In Chicago, the Shedd Aquarium has closed its doors to the public until at least April 30. In the absence of visitors, the center's rockhopper penguins have been allowed out to explore.
