As a result of egg and guano harvesting, oil spill pollution, and the impact of commercial fishing on prey sources, the status of the African penguin underwent a dramatic decline in the 20th century. The population of the species in the wild, which breeds in South Africa and Namibia, is estimated at less than 10 percent of the 1.5 million individuals that existed in 1910.
