The intelligence of squirrels is evident in their intricate food storage and retrieval strategies. They engage in deceptive caching, where they pretend to bury food to throw off potential thieves, indicating an understanding of other minds. Their spatial memory, crucial for locating thousands of hidden caches, is remarkably advanced.

13. Bees
