This morning a Sandwich Tern flew down-river, past the Deep Pit, where three Common Terns were displaying. A Kingfisher was on the river and a Treecreeper was seen hopping about on the path, picking up food items. The Grasshopper Warbler was reeling on the Deep Pit bank, overlooking the river and a Bittern was seen, flying between reed beds on the Slurry Lagoon. PS.
