Why are African penguins endangered?

They are listed on the IUCN Red List as "vulnerable" with population trend decreasing. The listed status is not "endangered" at this time. But to try to answer your question. This penguin is listed because it is suffering a rapid decline in it's population. The 21st century started with a tenth of the population that the 20th century started with. This is believed to be due to massive commerical fisheries causing shifts in types, and amounts of prey available to the penguins in their range. Plus, changes in their enviroment, such as water temperature fluctuations, and overall weather changes. Also, two wide spread oil spills in 1994, and 2000 affected over 40 percent of the population of the African Penguins, killing at least 30,000 penguins, that were accounted for. Then of course, the disturbance that man brings to their nesting sites, along with the harvesting of their eggs.
