The Funniest Thing

I saw the funniest thing this evening when I got home from work. I parked across the street and was walking towards the front door when I saw a bird chasing a squirrel down the sidewalk. Weird. I stopped and watched them for a moment. The bird was flying super low as to taunt the squirrel who attempted to flee up a tree, but being a bird and all, he was able to continue his attack as the squirrel went up and down the trunk. Not sure if they were fighting over something to eat or perhaps territory, but it made me chuckle!
