The partners take it in turns to incubate
their eggs and to feed their young. Historically they nested by burrowing into guano (bird droppings), but since the removal
of guano (for fertilizer) they have taken to nesting in sand or
under bushes.
Unlike many other types of birds, African Penguins breed all year round (but mostly mostly from February to May).
The females lay two eggs (although it is not common for both
chicks to survive), after which the incubation period is from 38 to 42
days. The male & female penguins share the incubation duties
equally. Each inclubation shift is typically two and half days
(depending on the availability of food).
