Urban Wildlife

My friend and neighbor, Warren, had me over for drinks and dinner the other night.  It was a gorgeous evening so we started by having cocktails in his backyard.  He showed me all of his new flowers and then headed inside to freshen up his drink.  As I was standing in the yard I had a distinct feeling that someone was watching me.  I checked at eye-level in every direction but couldn't spot anyone.  I decided to look up.  There on his roof was what looked like a squirrel's head.  It didn't move, so at first I thought maybe it was ornamental.  Then after a few moments it gave itself away by twitching its head but then became very still again.  I slowly got out my camera and shot the picture you see above.  When Warren came back out I told him to look up.  He did.  He smiled and asked if I could snap a picture.  I told him I already had.
