Penguin chicks starve in wake of oil spill
Penguin chicks starve in wake of oil spill An oil spill has threatened the largest colony of
the endangered Jackass penguin. Adult penguins have been removed
from Dassen Island which is situated off the west coast of South

the removal of the adults means that their chicks have now begun to
die from starvation. Jackass pengiuns are found only off the coast
of southern Africa. 4 JULY 2000
