Gray squirrels are ""scatter hoarders,"" collecting and burying one nut at a time throughout home ranges up to 7 acres in size.
It's impossible for them to keep an eye on all their caches at once. Other gray squirrels, as well as other animals such as blue jays, take advantage of these widely dispersed stashes to score a free meal. By some estimates, certain squirrels may lose as much as 25 percent of their cached food to thieving members of their own species. That amounts to a lot of nuts--mature squirrels eat as much as two pounds of nuts weekly and hide thousands throughout the year, particularly in late summer and early fall.
