Seen today in Etruria
that grey thing is a Heron, or as a little child that was passing said ‘an evil heron’! It really did look prehistoric.
At Etruria on the Cauldon branch of the canal. The bird walked along the canal towpath then stood crouched at the side of the water. It was ready to spear into the canal to catch a fish. More intent on staring than wo was watching it. I was amazed to get photos of it.
