A replica heron would be the same as a replica duck in the shooting season. Coelacanth is on to it. Put a hollow log up in the tree for a nest, sell your expensive goldfish and restock with el cheepo kingfisher tucka---sit back and enjoy. Many moons ago I was walking along the riverbank and heard scuffling and cheeping from a hollow branch and figured it was a nest. Curious to see what a baby looked like I put my hand in and Mother was there and very unimpressed. They have very strong and sharp beaks---my hand was not in there long.
