    Notes "The preceding days have been warm, clear and with little wind. Perfect autumn days. Today it wass clear, sunny with no wind and cool air temparatures before and just after sun rise. It warmed to mid 20's while we were counting. The main waterbody is full. There was not very much bird activity to be seen in the air over the Zandvlei and surrounding areas. There has been no rainfall this month after the highest rainfall in March for the Zandvlei area in 18 years, by the rainfall data collectors. A highlight here was a Hottentot Teal, a species long last seen here. We saw a Tropical Tent-web Spider in its nest (Araneidae: Cyrtophora citricola) and a Cape Rain Spider (Sparassidae: Palystes castaneus) a new nest, which is late in the season. They must know something or are taking advantage of the prevailing weather conditions. There are not any visible flying or crawlings insects to be seen. No dragonflies along the waters edge. The swale along side the railway near the railway bridge is visible after about 40 years being concealed by overgrown vegetation. It is interesting to note that the water level in the swale is at the same level as the water flowing under the railway bridge. The phragmites reed shoots are pushing up after the 2nd week since the fire on Easter Friday. Due to helpers being unavailable there were no counts done today for the northern and southern Marina canals or the night heron canals. "
