Dyer Island, South Africa, supported the largest African penguin Spheniscus demersus colony in 1979 (22 655 breeding pairs), but population dynamics of the species have not followed the trends of adjacent colonies in years of high fish abundance or shifts in prey distribution. Less than 1 500 pairs were breeding on Dyer Island in 2013. Available knowledge on demographic parameters was collated and ecological processes were quantified. Juvenile and adult survival probabilities estimated for… 

A changing distribution of seabirds in South Africa—the possible impact of climate and its consequences

In the southern Benguela ecosystem off South Africa, there were recent shifts to the south and east in the distributions of three forage resources (anchovy, sardine, rock lobster), which probably

Hand-Rearing, Release and Survival of African Penguin Chicks Abandoned Before Independence by Moulting Parents

The feasibility of conservation translocations for the creation of new colonies for this species using hand-reared chicks warrants investigation, and any such programme would be predicated on adequate disease surveillance programmes established to minimise the risk of disease introduction to wild birds.

Intercolony variation in reproductive skipping in the African penguin

Abstract In long‐lived species, reproductive skipping is a common strategy whereby sexually mature animals skip a breeding season, potentially reducing population growth. This may be an adaptive

The Benguela Current is used by c. 82 seabird species, of which seven are endemic to it. Eggs and guano of formerly abundant seabirds were heavily harvested in the 19th and 20th centuries but

Demographic parameters, foraging and responses to environmental variation of little penguins (Eudyptula minor)

Investigation into the demographic parameters, foraging behaviour and relationships with environmental variations in an increasing population of little penguins (Eudyptula minor) at Oamaru, South Island, New Zealand found median lay date, breeding success and the proportion of females double brooding were highly correlated, indicating that high breeding success was attributable to the regular occurrence ofdouble brooding.

Annual variation in recruitment and age-specific survival of Little Penguins, Eudyptula minor

A multi-state capture-mark-recapture model was used to examine survival and recapture probabilities of known age penguins flipper-banded as chicks, and breeding penguins of unknown age banded as adults and detected no significant effect of age on survival.

Food limitation and minimum viable populations of seabirds in the Benguela Current Large Marine Ecosystem

Evidence for food limitation of seabirds that breed in the Benguela Current Large Marine Ecosystem (BCLME) is summarized below. Ecosystem considerations and EAF (ecosystem approach to fisheries)




Both fledging success and immigration of immature birds to the colony were significantly related to the spawner biomass of Cape Anchovy Engraulis capensis, the most important prey item of penguins at the island.

Influence of local and regional prey availability on breeding performance of African penguins Spheniscus demersus

Breeding success and chick-fledging rates increased during the study period and showed positive relationships with local food availability, indexed through the annual industrial catch of anchovy made within 56 km (30 nautical miles) of the colony.


Over a period of 10 years, time elapsed between banding and recovery did not differ significantly between cleaned and non-oiled penguins, as shown by a randomisation test.

Artificial nests enhance the breeding productivity of African Penguins (Spheniscus demersus) on Robben Island, South Africa

An investigation into the effectiveness of providing artificial nests for the endangered African Penguin at a colony on Robben Island, South Africa, supports findings from Namibia, and also supports the continued use of artificial nests as a conservation tool throughout the range of the species.

Trends in numbers of Kelp Gulls Larus dominicanus off western South Africa, 1978–2007

The number of Kelp Gulls Larus dominicanus breeding at 11 islands in South Africa's Western Cape province increased during the period 1978 to 1999–2000 and then decreased and resulted from predation of gull chicks at some colonies by an increased population of Great White Pelicans Pelecanus onocrotalus.

Influence of feeding conditions on breeding of African penguins—importance of adequate local food supplies

Off the coast of South Africa, the 2 most important prey items for African penguins Spheniscus demersus are sardine Sardinops sagax and anchovy Engraulis encrasicolus, species heavily exploited by

African penguins as predators and prey – coping (or not) with change

Stochastic modelling suggests that colonies of 10 000 pairs have a 9% probability of extinction in 100 years, so smaller populations should be regarded as "Vulnerable", however, in a period of prolonged food scarcity off southern Namibia, the regional population decreased from more than 40 000 pairs in 1956 to about 1 500 pairs in 2000, and many colonies numbering less than 1 000 pairs became extinct.

Collapse of South Africa's penguins in the early 21st century

The number of African penguins Spheniscus demersus breeding in South Africa collapsed from about 56 000 pairs in 2001 to some 21 000 pairs in 2009, a loss of 35 000 pairs (>60%) in eight years. This
