    Notes Clear blue sky, initailly the morning was cool, from a clear sky night with no wind. Little to no wind till about 10h00. Slight SE breeze for duration of the count. It is felt that Thursday and early Friday morning which had an almost gale force SE wind blowing continuously, was the contributing factor to so few birds present at Zandvlei. By 11h00 it was probably 25 degees C with slight SE breeze. The estauary mouth was closed. Note that no count took place in the Marina da Gama channels. The water inflow under the railway bridge was 1 metre per 20 seconds. The water was still very turbid at the confluence at the railway bridge. In the vlei main body the visiblity was very good. The preceding days SE wind may have influenced the clarity of the water from the wave action generated. The most observed birds in the air were the African Darters. There were very few birds on the water and in the air as per the photos. A Black Sparrowhawk was seen carrying a part catch of something and was flying west across the Westlake Wetlands at about 25 metres high, with an adult Fish Eagle as an escort keeping pace and an even distance towards Pollsmoor area. Unusual behaviour not seen before.
