Looks like someone needs to put down the acorns.

Thanks to unseasonably warm winter weather, squirrels are fatter than normal this year, says evolutionary ecologist Dr. Andrew G. ­McAdam. Lack of snow makes it easier for them to sniff out food, and they have to expend less energy to keep warm. While they normally might be hunkered in a den this time of year, instead they just keep eating.

Social-media users have delighted in the nutty phenomenon, posting photos of tubby Rocky with hashtags such as #fatsquirrel and #fatsquirrelseason.

McAdam says the squirrels should suffer no ill effects because of the added weight and will naturally lose the extra pounds by spring. If not, “they’ll have to get a gym membership,” he quipped.
