Every year, 1 or 2 herons visit the estuary. If we are lucky, they will stay all winter. If not, they might stay for a few days. Whenever they do visit, it is very special. They are stunning birds. Last weekend a visitor arrived to feed in the shallow tidal waters of the estuary and it has stayed for the week. It sometimes associates with the royal spoonbills but will move east along the mud flats to feed.
