African penguin Reproduction: The Egg


African penguins reproduce by laying eggs. The female penguin will lay two eggs about three to four days apart. Eggs are produced usually after three weeks of nest building and many successful occurrences of copulation. Post copulation, internal fertilization occurs. As the egg travels down the female reproductive tract it builds the albumen (egg white), yolk sac, yolk membrane, shell membrane and shell. The egg is then passed out through the female’s cloaca. The yolk sac is the main food supply for the developing embryo and includes protein, fat and minerals.-Pamela Schaller

African penguin Conservation: Uplisted to Endangered by the IUCN


It is official, according the IUCN website the African penguin has been uplisted to Endangered A2ace+3ce+4ace ver 3.1. This is due to a very rapid decline in the population for the varied reasons listed in our previous blog posts. The population is now at 52,000 mature individuals. Some of the main Conservation Actions include: Monitor population trends, continue/maintain SANCCOB oil spill rehabilitation centers, initiate research into the impacts of fishing and predation, management of purse-seine fisheries, determine source of and prevent chronic oil spills, investigate reintroduction and translocation techniques and several more. You can follow this link directly to their African penguin information.-Pamela Schaller  IUCN Redlist
