Amid the previous a very long while, the predicament of the red squirrel has developed particularly concerning, driving the Red Squirrel Survival Trust to extend that the species could go wiped out in the U.K. inside the following decade if numbers don’t turn around.
To make sense of how dim squirrels are outcompeting their British cousins, University of Exeter squirrel conduct master Pizza Ka Yee Chow examined the jittery followed rodents at both her college grounds and on the Isle of Arran, off Scotland’s West Coast.
