Below the High Water Mark Challenge

Just to clear up some rules for this competition which you have hopefully started already, please note. Birds can be included if seen below and/or beyond the high water mark, but not around lagoons. Thus a bird seen flying over a bay, for instance, can be included even if it is not a pelagic species. Birds on offshore rocks can also be included, however, these must be within 50 km of the SA coastline.
