Résumé :	The world population of the African Penguin (Spheniscus demersus), a vulnerable species confined to South Africa and Namibia, is estimated to be 180 000 birds; 10 000 were oiled in the "Apollo Sea" spill in June 1994. Of the 5000 penguins that survived to be cleaned and released, 4076 were fitted with flipper bands. Over the following five years, the resightings database of these birds grew to 40 000 records, relating to 2961 inviduals, 73% of the number banded. Using an average survival rate for African Penguins of 85%, it was estimated that about half the birds remaining alive at the start of each of five successive years were resighted within it. The results indicate that the cleaning techniques for oiled African Penguins are successful, and that the survival rates of these birds do not differ from those of normal penguins.
