Ground squirrel tail-flagging appears to operate as a predator-deterrent signal through two distinct mechanisms. Their burrows may contribute to soil aeration, based on similar practiced by round-tailed ground squirrels.

Many ground-squirrel species hibernate for most of the year, spending only 3-4 months above ground in the summer. The large numbers of eyes on the constant look-out, help to detect any possible threats from advancing predators.
