When I approached the loch this morning, I spotted 2 heron on the rooftops. When I went into the park they flew down, to be joined by another 2. I had taken less fish but had enough. The heron that met me were, the little female (pictured), the original young one, the nervy one (who was still a bit nervous) and hyde.I managed to feed them all although it was half rations today. I noticed that all the gulls had gone which probably confirms my theory that they were the problem.
