Resting close to the Cormorants but apart from them. I don't think it's a cormorant.
No interactions present.
It is easy to distinguish this from a Shag. Shag has a thinner beak; has a steep forehead which peaks at the front, not at the back as in this bird; and Shag lacks the yellow patch at the base of the beak.

My first thought was that it was a large Cormorant. It looks just like the white-breasted ones we have in Cape Town but my UK refs didn't indicate the option.
This links to some of the SA sightings of the Whitebreasted Cormorant
Sorry, first link didn't work.

Respect to Tony Rebelo. I think he has more badges than I have had hot dinners, truly.
