Yes, it’s time for another heron ( I really can’t get enough of these magnificent birds). One at my local lake.  Little different because, despite it being a wet summer with tons of rain, this year were have a lot of weed (green algae) in the shallows and this seems to be obscuring small fry min the shallows.  Heron answer. follow them and set up a watch on a couple of stakes.  It seems to be working for this one who has made them its own for the past week or so.
