    Notes Comments: (including any factors that might have affected the results, e.g. rain, wind, water level, disturbance, threats, etc. Also include any other information related to the species observed, breeding information, counts, etc.) A sunny clear sky with a gentle SE wind blowing. On the Thursday night and early Friday morning preceding the count it had rained. It was hoped this change in weather would increase the species and numbers but did not seem to have an influence. The inflow speed of the Westlake and Keysers Rivers into Zandvlei at the railway bridge was measured at 1 metre per 10 seconds. The estuary mouth was open. On the main water body there were not many birds to be seen. The Marina north and south sections were counted and helped boost the species and numbers as this is where many birds were sheltering out of the wind based on the count. Usually there are hundreds of Coots on the mainwater body at this time of the year. Very few to be seen, they were in the Marina canals. The Egyptain Geese were in the Caravan Park sheltering out of the wind too. The water level was quite low with much of the sand bar exposed down to the the second bend from the mouth. The Caspian Tern figures were back and up to the Jan 2012 count. A side observation I have never seen Boswell Circus at Zandvlei before. The operation was setup in the braai area on the western shore which falls under the City's Parks Dept.
