African penguins look much like the Humboldt penguins. African penguins have a broad band of black that is in the shape of an upside-down horseshoe on their fronts. There have black spots scattered over their chest area. They make a loud braying sound that has given them the name the "Jackass penguin". They stand about 27 inches (60 cm tall) and weigh from 7 to 11 lbs. (2.5 to 4 kg).
African penguins live and breed on the coast of South Africa and on the off shore islands. During the 17th and 18th century the African penguin was killed for food and oil. More recently the collection of guano has destroyed nesting areas. At one time the population was estimated to be in the millions. This number has decreased to about 160,000 in 1993.
The African penguin is a protected species, but their habitats continue to be damaged by oil spills from tankers off the Southern coast of Africa. Recently a successful effort has been made to establish new breeding colonies of the African penguins in the area. There are also rescue services to aid penguins that have been harmed by the oil slicks.
The nests are built far apart from other nests. They can be built under bushes or on sandy beaches. Two eggs are usually laid and in years when there is plenty of food both chicks will survive. Incubation takes 38 to 41 days for the the eggs to hatch. This task is shared equally by both parents taking a 1 to 3 day shift. The chicks are kept warm and protected for about 40 days after hatching by both parents. The chicks get their adult feathers when they are 70 to 100 days old. At this time they go to sea and are on their own.
