    Notes The weather was not ideal for bird counting. The sky was cloudless and sunny with a howling cold SE wind, blowing at what was reported to be 65kmp. The estuary had waves generated by the wind and its level was full. Sheltered in the Promenade Road reed pond were a pair of Cape Teals and a Little Egret. It was surprising there were not more species in there, as it was wind free. It was full moon to day. There was no water flow at the railway bridge, the surface water was being blown back into the confluence of the Keysers and Westlake River. The NW bank of the scout basin was being eroded by the wave action of the high water level. A note about the colour of the water in the upper reaches, it was a pale greenish colour suggesting it was almost pure sea water captured by the opening and closing of the estaury mouth. It would be interesting to see the salinity reading. The night heron roost and the northern canals of the Marina were not counted due to the strength of the wind for canoeing.
