13-liners love short grassy areas, and adopt cemeteries readily. As the animals are colonial and dig extensive underground labyrinths, their presence doesn't always sit well with cemetery managers and they sometimes are eradicated. I hope that doesn't happen here.
Thirteen-lined Ground Squirrels are no dummies. They thrive in the warmth of spring, summer, and fall. If things get too hot above ground, a cool subterranean retreat is never more than a few paces away. Come the cold, ice, and snow of winter, the squirrels go underground and sleep right through the whole mess. Not a bad gig!
