Hazlenuts

We've had squirrels in the garden for years. We can go for months without seeing them, then they never seem to be away from us. 
I bought a bag of hazelnuts and spread them around the patio and on top of the hot tub. Today, one squrrel singlehandedly took them all, we watched him collect them one by one and then run off and bury them. It took him hours, hope he remembers where he left them!
