Just thought I'd update this. I was back at Milne park yesterday and while sitting on a park bench on the beach observerd 5 great egrets, no less than 3 GBH, 2 common terns, 2 belted kingfishers diving for fish (both looked to be females by colouring), a handfull of sandpipers, an assortment of gulls and waterfowls, Canada geese, and watched the (or one of the) osprey fishing (flying from tree to tree, overing, and diving for fish). A good day.
