Normally, there is a blizzard of activity in the yard as squirrels scurry about pestering the cardinals at the bird feeder and digging in my plants. One afternoon, the movement all stopped and one little squirrel suddenly froze on the side of the oak tree.
So, I went to see what was going on.
Here is what was going on. Apparently, this guy stopped in for a break and terrified the squirrels. He sat in the tree for about a half an hour, and that frozen squirrel never moved the whole time.
