Cape Peninsula 2

Eighteen days later, the first bird of the group was seen arriving at Mercury island off Luderitz, over 1 000 kilometres away. The same bird was spotted on Robben Island – less than 10 kilometres from the Cape Town – four days after being released from Derdesteen Beach. Given this confirmed sighting, it would mean that his actual swimming time from the Western Cape coast to Luderitz was an incredible 14 days, over which he averaged 72.7km per day.
