Standoff

I was on my lunch walk and saw my hawk friend on a tree about 5 feet from the sidewalk.  It took me a couple of minutes to see the squirrel on the same limb, staring him down.  They stayed that way for at least 5 minutes with me clicking away, when suddenly the hawk turned his back to me and fluffed his wings.  I thought he was going to fly away, but he turned to his left and started running towards the squirrel.
I know I should let nature take its course, but I couldn’t - I yelled at the hawk and it flew off to a nearby tree and when I didn’t leave, it flew off.  I was feeling pretty good about the situation until the squirrel I had helped ran down the tree and started barking at me like I had chased his lunch away.
