Cougars are recolonising the mid-western United States, according to scientists, reversing 100 years of decline. The population of big cats, also known as American mountain lions, has rocketed in these states, from less than a hundred in 1990 to about 30,000 today.
Michelle LaRue from the University of Minnesota said that the midwest population of cougars had been "effectively zero" two decades ago. "That's why this is so exciting," she said. "We have hard evidence that the western population has spread."
The cougars are one of my must-sees everytime I visit the Zoo, simply because they are so beautiful.
I thought we needed something happy-making today.
