WHO ARE YOU CALLING FAT?
Wild bears living near US towns and cities are getting fat from eating the left-overs of fast food meals, researchers have found.
High-calorie, high-fat diets have led to record levels of obesity among people and even domestic pets in the US.
Now, a study in Nevada by the Wildlife Conservation Society has found that black bears living near urban areas are picking up the poor eating habits of their human neighbours.
By tagging 59 bears, they found that the animals fell into two distinct groups.
One group, dubbed "country bears", spent nearly all their time in the wild.
The second group, "city bears", virtually lived in urban areas and feasted on the rubbish and left-over food of local people.
Come winter, country bears spent more time in their dens, avoiding the cold and lack of food outside.
But city bears took advantage of the year-round supply of left-overs and kept on eating, the study found.
The end result was that the city-dwelling animals were fatter than the average bear.
A quarter weighed over 400lbs, compared to an average of 220lbs-300lbs. Some weighed between 500lb and 600lbs.
