Squirrel Grooming

I have a lot of large oak trees on my property and a rather large population of squirrels inhabiting the area. I love to practice my skills by shooting them and ocassionally come up with a gem. I was in my house, heard some squirrel sounds emanating from the backyard, and when I went to investigate, I found these two chasing each other around. I decided to get my camera, and was rewarded by a series of shots, this one being an example. I have never seen squirrels relating in this close a manner - just romping around with each other. Another shot I have in this series shows the bottom squirrel with his eyes almost completely shut as if just absolutely enjoying this experience. It was tough deciding which to post, but I went with the one with eyes open.

The photo was shot with a Canon 70D and Canon 100-400 L lens at 170mm.
