    Notes To carry on the raptor sightings a Peregrin Falcon came over the yacht club basin and the Harrier Hawk was seen twice more patrolling around trees in the suburb nearby. The Water Thick knees have moved to the Caravan Park as there is too much activity at the Scout Base at this time of the year. The rehabilitated seasonal wetland opposite The Outlook offices and next to the railway line, is in its 3 winter and is looking established and very good habitat for waterbirds and other associated creatures. African Sacred Ibis were feeding in it today. There are major gabion walls being installed below the Thesens bridge and above the Royal Road bridge to protect the sand banks eroding from the in and out flows of the estuary near the mouth. Then an unusual activity in a Norfolk Pine tree on the corner of Axminster and Royal Roads. We counted 6 nests being built by 12 Grey Herons and there could have been more, as sticks were being carried into the tree by circling birds using the air up draft off the flats next door. This must be desperate measures and are the birds trying to tell us something about the impact the burgenning numbers of humans choosing the suitable deminishing Cape Town habitats to make their homes in. The Night Heron roost in the Nature Reserve was decimated by fire wood cutters in January 2023 and they had to disperse after 23 years at their roost. See the photos of the exposed sand banks and the interesting path the water has chosen to flow through the "cookie cutter" as it was dredged deeper last year
