| Brief_description |
| Counts are done from the "shacks" on the Vlaminkvlei side, or alternatively from the fish factory on the Port Owen side. Counts are conducted during the last two hours of daylite. During this time, the numbers of mainly Cape and White-breasted Cormorants that come in from the ocean to roost on the mainland are recorded. The main roosting sites for these species are the Cerebos saltworks, up to 15 000 birds, as well as possibly the Kliphoek saltworks. Figures indicate numbers of cormorants peaking during winter months with a peak of 36 230 Cape Cormorants recorded during August 2007. The Lower Berg River System serves as a major night roost site for various species of waterbirds. |
