We have been helplessly watching a very industrious squirrel raiding our walnut tree but his greediness got the best of him. I noticed some unusual green at the base of our very old, damaged apple tree. On closer examination I found walnuts buried in the surrounding fir cone midden and more walnuts in the hollowed out tree. I gather about 15 pounds worth of nuts, leaving some for the squirrel.
Hard-To-Come-By Lifestyle 
How convenient! At first glance I thought those were green apples in the hollowed out tree .
We really appreciate him doing the picking for us but he’s not too happy. Now his stockpiling our hazelnuts.
Unbelievable!
One well prepared squirrel!
