The life of a squirrel

I have a yard full of squirrels and I cannot figure out their philosophy on life. We sat here one day and watched one particular squirrel. He came down along the wooden fence with a nut in his mouth. We watched as he scurried along the back yard. He would stop and look up, still holding his hickory nut. He would glance furtively around, looking for spies. He would run a few more feet, stop, and repeat the process. After three or four minutes of this procedure, he would dig a small hole and bury the nut. He then ran around the yard to various spots. He would stop and sniff around. Then he would run back, get the nut and take it to the new spot and bury it. How crazy is that? Apparently, eating a lot of nuts will make a squirrel nuts. He repeated this about four or five times, burying the nut, digging up the nut, over and over. Then he dug it up and ran up on the patio, climbed in my petunia bed and buried it there as it's final resting place. Then he left. He is back this morning. Only this time, he is outside my window on the ledge, eating the bird seed that has fallen from my bird feeder. I slowly opened the blind as to not scare him off. He tried to climb up the window screen. Guess I have a new pet. I think I'll buy a bag of unsalted, shelled nuts and make his job a little easier this winter. Think I'll name him Sammy. Stay tuned for more of his antics as winter progresses.
