    Notes "Thank you to Gasan Moses who counted the southern Marina canals today by canoe. We found the pair of Water Thick-knees again in their secluded area. There was a mobbing by gulls and cormorants moving about the vlei indicating shoals of fish being chased. Luckily we did not have to count hundreds of coots this quarter. The pond weed has not come back yet, and this is probably due to the high salinity throughout the main waterbody and the Marina canals and even into the Rutter Road Pond. Felicity found a turquoise egg with a broken shell and a chick inside. It looked like it had been broken open by a bird, probably to eat or to prevent the hatching. The water level was very low as it was low tide, which just started to ripple into the estuary as we finshed counting at 11h15. The water flow towards the mouth was also measured at 1 metre per 6 seconds near the Thesens bridge. By then the sky had cleared to bright sunshine with a strong SW wind blowing. A month ago A Familiar Chat made an appearance in the new nursery at ""The Lookout"" offices. This species was last recorded in 1975 at Zandvlei."
