Endangered Penguins

Many penguins are endangered, or at risk of dying out completely. Endangered penguins face the threat of extinction for several different reasons. One major threat to penguins is pollution. Pollution can kill food sources, which causes penguins to die out. Oil spills also also harmful to penguins. Some penguins live in the forest, so deforestation, or clearing out trees, is another cause of endangerment.
Icebergs are another threat to penguins. These large blocks of ice can block routes to food, making it difficult for penguins and their chicks to survive. Sometimes, other birds try to eat penguin eggs. Only about 90% of penguins' eggs actually hatch, and those chicks can be at risk if they have to survive extreme weather conditions as well as predators.
Penguins that are currently or have in the past been considered endangered include galapagos, african, chinstrap, king, macaroni, magellanic and rockhopper penguins. The yellow-eyed penguin is considered a vulnerable species, because it has experienced a 40% decrease in population in the last 40 years.

Threats to Penguins Habitat

Penguin habitats continue to change, as they have for the past century. Scientists believe that global warming is responsible for many of these changes, leading to conditions that threaten penguins and their habitats. Rising temperatures in colder areas lead to less ice on which penguins can live. Increased heat in temperate climates leads to more deaths among penguins. Melting sea ice and warming waters lead to starvation, due to disappearance of the cold water species on which penguins feed. The stresses affecting penguin habitats may also prevent penguins from reproducing, leading to smaller penguin populations.
