Squirrel squabble

Nibbles has been visiting our garden for a couple of years now. He was happily burying his nuts, amongst my new planter and enjoying a sip of water from the fountain, until a new, young whipper snapper turned up!
Well that was it, Nibbles chased him around, up the tree, down the tree, over the fence. 
For now, the new one ( only young) has left but I have a feeling , he'll be back. So we will name him Arnie ( he's a bit skinny)
