Feeding frenzy

Fellow blippers and friends ChrisA and IAE made a little detour to visit me on their way home from a holiday in Scotland.  We had a walk at Port Carlisle where the tide had just started to go out and we spent ages watching this feeding frenzy.  There were seven herons who were eating fish after fish, three egrits and lots of black headed gulls.  I've not seen this before despite it being a regular walk for me.
