Red squirrels, like their cousins the grey squirrels, eat a variety of food ranging from eggs raided from birds’ nests to nuts and pine cones. Pine cone seeds from the major part of their diet. These are methodically stripped from the pine cone. The squirrel nibbles out the seeds along on edge, and then, rotating the cone with its front paws, it strips out another line of seeds.
What may surprise you, however, is the amount of pine cones that a squirrel eats. It has been calculated that a single squirrel can eat its way through 40,000 pine cones in a year.
