do squirrels remember where they bury nuts

Squirrels do remember where they bury many of their nuts, using excellent spatial memory along with other strategies. They organize nuts by type into separate caches and "chunk" these locations to reduce memory load. Studies show squirrels recall their own cache sites even if other squirrels cache nearby, indicating they remember specific locations, not just using smell. They also sometimes revisit caches and rebury nuts to refresh their memory and confuse potential thieves. While squirrels do forget some nuts or abandon some caches, they generally have a purposeful system for caching and recovering nuts rather than burying them randomly or forgetting most of them.
