Closest relatives are humboldt and magellanic penguins found in southern south america and the Galapagos penguin found in the pacific ocean near the equator
Ancestors
Likely a flightened bird
Black stripes
Black spots on chest
Pink glands above eye (becomes pinker as it gets hotter)
26.5-27.5 inches tall
4.4-11 pounds
Beaks are 20-30 centimeters
Males are bigger than females
Males have bigger beaks
Average lifespan is 20 years
Flat sandy areas
Costal areas
Offshore islands
Sparse vegitation growth
steep/rocky sites
They compete on land with cape fur seals, gannets. cormorants and other sea birds
5-20 degrees celcius
41-60 degrees farnehieght
South-western coast of Africa
Live in colonies on 24 islands between Nambia and Algoa Bay
No they are not invasive
Diet consists of pilchards, round herrings, anchovies, horse mackerel, and other shoaling pelagic fish. The birds will also consume squid and crustaceans.
1 pound of fish per day
They hunt in groups of by themselves
Their diet differs from region to region but it mainly consists of small fish
They live in large packs
They are a food source for sharks and seals and also act as predators to small fish such as anchovies and sardines
Groups consits of both males and females who are ready to breed
Individual's that make up the groups are breeding pairs
African penguins communicate with one another through vocalizations and body language. Each individual has its own unique vocalization that distinguishes it from the others.
Once yearly
They're monogamous (breed with one partner for their entire life) unless breeding has failed for some reason, then they will take another partner
May-August
Complex courtship displays performed by male and female; includes behaviors such as bowing and embracing.
1-2 eggs
They only mate with 1 person for the rest of there lives
Stages of Devlopment:
Egg
Hatchling
Chick
Juvenile
Adult
3-8 years to reach sexual maturity
The first moult occurs after 14 days followed by a second moult at 40–60 days, and juvenile plumage develops at 70–80 days. The chicks are fully fledged after 70–90 days. The fledgling juveniles will go out to sea on their own and return to their colony of birth after about 12– 22 months to moult into their adult plumage.
Males have slightly thicker beaks comapred to females
Predators:
Mongoose
Genets
Leopards
Carcals
Domestic cats
Sea birds also steal eggs and kill baby penguins
Diseases:
Aspergillosis
Avian malaria
They can also die from:
Increasing shipping traffic
Oil spills
Pollution
Climate change
Extreme weather events
Inter-species:
Kelp Gulls
Large herones
Rats
African Ibises
African penguins also compete on land with Cape fur seals, gannets, cormorants and other sea birds for breeding space.
Listed as endangered
The global population is estimated at 18,500 pairs, with 13,200 in South Africa and ~ 5 300 in Namibia
The current driver of there population decline is food avalibility
Humans cause a threat to African Penguins due to exessive fishing of the Penguins prey, oil pollution and entanglement of fishing gear
The population of African penguins has declined over 95% since pre-industrial times and its estimated that the species will go extinct by 2026 if current climate change and human activity trends continue.
Humans and African Penguins have been interacting since 1979
Things being done to help:
Hand-rearing-chicks- They rescue orphaned chicks, which are then hand-reared and released back into the wild when they reach fledgling age.
Formal protection of breeding colonies by converting areas with known breeding sites into nature reserves and national parks
Prohibiting the collection of guano and eggs
Establishing marine protected areas where fishing is prohibited
Ongoing research to monitor population trends in relation to prey availability and disease outbreaks
Active management of population sizes of predators
Artificial care of abandoned chicks
Providing artificial nests
Rehabilitating sick birds.
