An exceptionally mild winter in many parts of the world appears to be contributing to squirrels gaining inordinate weight in both Europe and North America.
The warm weather has meant the trees still have an abundant feast of nuts and seeds, which the squirrels have been taking advantage of.
Squirrels do not hibernate, so to survive the harsh winter, they fill up with reserves at the end of the year to accumulate fat.
Iolo Williams, a BBC presenter and wildlife expert, explained how this weather has led squirrels to have an extra thick layer of fat this winter.
