As fall settles in, this wildlife spy wonders about animals who dig in for the season — or all winter. People aren’t the only creatures who adjust their surroundings to their needs. Shelter is essential for survival, and some critters aren’t leaving it up to chance.
Animals dig out dens or burrows for several reasons, but they all boil down to one common factor: They’re staying in one place for a while and need shelter. An underground residence makes good sense; dirt is a good insulator, keeping temperatures cooler in summer and warmer in winter than open air.
