European Grey Heron

I think this is quite a young Heron as it is not very tall.It seems to have taken over the territory of the more mature bird that was there last year?
   Not far from this spot on the River Avon between Bristol and Bath is quite a large Heronry or Heron Rookery as some call it. Of 6 or 8 nests.
   Proving that there is a large enough food supply.Including some domestic fish ponds no doubt?
   Here it is enjoying a good stretch after long bout of fishing,no doubt.

  Change of camera and lens on this shot too by the way?
