Good job a $$££ human ££$$ caused this incident, what on Earth would they do if 'the damage' was done by seals or other such preditors...or even by disease!
In 1979, this disease caused the deaths of about
5000 Cape Cormorant Phalacrocorax capensis chicks and 100
Bank Cormorant P. neglectus chicks at Mercury Island, Namibia

If I may be allowed to refer to the first post in this thread;
Hundred of nests of the most endangered seabirds – Bank Cormorant, African Penguin and Cape Gannet – were destroyed. This amounted to the killing of around 600 incubated eggs and chicks.
It's the old human/nature 'who does the most damage' argument again, only nature isn't much of a $$££ giver in the courts!
p.s. Don't miss the bit in the article that mentions that increased scientific research leads to the introduction of disease to remote locations.
