Get OUT of my bath!!

I watched this blackbird guard this pool ferociously for a few minutes.  First a pigeon flew down and wandered round the pool being watched closely by the beady eye of the blackbird.. the pigeon decided against having its bath just then and flew off. The Sparrow was braver.  As the blackbird was splashing about it hopped closer and then finally dared to hop into the pool where it sat and the two of them had a stare off!!  l thought the blackbird was going to tolerate the little sparrow sharing the pool but as soon as the sparrow dipped its beak into the water the blackbird pounced.. this is the Exit left (backwards) moment!!
