Up in a branch of a fir tree, I hear the whistling call of a squirrel. Well it has nothing to worry about from me. It leaps acrobatically from branch to branch. Then it peers down at me from a higher vantage point.
I think it must be busy gathering nuts for the coming winter, and I’m just a noisy distraction walking past it. But it pauses for a while to watch me pass. It whistles an “all clear” to other squirrels after I have passed.
I hope finds lots of nuts.
