Birds in the Bunker

This is an accidental backblip as I have just discovered it on my compact camera as I was checking it before going on holiday soon.

Taken during a game of golf a couple of weeks ago we were approaching the 10th green and were confronted by a large flock of rooks on the green, in the bunkers and generally all around and when we started putting we found large holes on the green where they had been probing with their powerful beaks. 

We often see them on the golf course, usually on the fairways, as there are many nests in the trees beside the course but I have never seen quite so many of them and particularly not damaging the greens like that.
