Bears roam the streets of Italy, and herds of goats pop up in Welsh towns. In Israel, a wild jackal was spotted on a trail in Tel Aviv. This is what happened around the world in early 2020, when lockdowns were imposed around the world due to Corona 19. As the number of people decreased, the exotic scenery of wild animals that came down to the villages where people live received great attention every time.
Did real animals move more comfortably during Corona 19? On the 8th (local time), in the American scientific journal Science, the movement of terrestrial mammals was actually tracked. research results published
This study, in which 175 experts, including a research team from Radbau University in the Netherlands, participated, in Brazil, Norway, Kenya, Asia, and other countries. GPS data from 2,300 terrestrial mammals of 40 species, including bears, deer, and elephants, were used.
The research team explained, “In 2020, when the pandemic was declared, many animals around the world tended to move farther than before and move comfortably.” In particular, as a result of analyzing the travel distance for 10 days when strict lockdown measures were imposed, it was found that it increased by 73% compared to the same period last year.
Brown bears in the Italian Alps are known for their timid nature, but they have shown bold behavior, such as raiding chicken coops and looting garbage cans. It was analyzed that pumas in California also walked in the middle of the streets as they moved closer to the city center when the San Francisco Bay Area was blocked.
During this period, the amount of movement per hour of terrestrial mammals decreased by 12%. This was also interpreted as the basis that the animals went ‘comfortably’. “Because humans who frighten animals have disappeared.”
Radboud University ecologist Marley Tucker, who led the study, said: “It is clear that we are influencing animal behavior. What is surprising is that small changes in our behavior can be quite positive (for wildlife).”
It was also noteworthy that these behavioral changes appeared in a very short period of time. digNada University of Alberta professor Colin Cassady St. Clair (not a participant in the study) said, “This characteristic means that many wildlife species are quite sensitive to human activity.”
However, the reduced human intervention has not only worked positively for wildlife. The WP made the announcement, citing examples such as the halting of work by researchers who had been removing invasive rats to preserve seabirds on Gough Island in the South Atlantic Ocean during the pandemic. In addition, on the island of Stora Calso in Sweden, the number of white-tailed eagles increased sevenfold as tourists disappeared, threatening seabirds.
