This squirrel has been a resident in the trees behind our house for five years. He’s feisty and acts like the backyard, our deck and everywhere else he travels is under his dominion. In this encounter I had my feet up on the railing and he squared off staring at me. It became pretty clear that he was impatiently waiting for me to put my feet down so he could pass. I obliged, but snapped off a couple of frames before removing the barricade. He chirped as he ran by and kept up the chatter as he climbed up a tree. I thought a simple thank you would have sufficed!
