Macaroni penguins have evolved to cope with the highly variable conditions of the Southern Ocean. However, changes in prey supply and patchiness potentially associated with changes in climate and krill fishing activity may be occurring too rapidly for the penguins to adapt. We use a stochastic dynamic programming model to examine how changes in both the mean and patchiness of krill supply may affect the foraging decisions, and therefore breeding success, of female macaroni penguins at South… 

Inter-population segregation in the wintering areas of macaroni penguins

It is concluded that inter-annual fidelity in winter habitat provides evidence of highly favourable and predictable foraging areas, while the distinct inter-colony distributions suggest very heterogeneous distribution of profitable feeding areas for this species in the southern Indian Ocean.

Climate variability and multi-scale assessment of the krill preyscape near the north Antarctic Peninsula

It is found that across years, krill abundance and variability are correlated with seasonally averaged measures of El Niño-Southern Oscillation at lags of approximately 2–2.5 years, which may correspond to strong reproduction and recruitment events.

Foraging behaviour and population dynamics of northern gannets over a period of environmental change

Gannets were also flexible within breeding seasons in the foraging and parental effort they expended, suggesting that the chick’s requirements also contribute to adults’ foraging behaviour, and support models of foraging based on competition for prey around seabird colonies.

Diving patterns of female macaroni penguins breeding on Marion Island, South Africa

Investigating the diving behaviour and diet of female macaroni penguins feeding small chicks on Marion Island, South Africa, confirmed the behavioural flexibility of these birds reported from other breeding localities and suggests that at least some prey are caught during shallow dives.

A Space Oddity: Geographic and Specific Modulation of Migration in Eudyptes Penguins

The results show that inter-breeding migration patterns in sibling penguin species depend primarily on the site of origin and secondly on the species, supporting the hypothesis that migration behaviour is affected by the intrinsic characteristics of each site.

Behavioural switching in a central place forager: patterns of diving behaviour in the macaroni penguin (Eudyptes chrysolophus)

Diver data is taken from 103 breeding macaroni penguins at Bird Island, South Georgia, and a hidden markov model (HMM) is applied, which is a machine-learning technique that seeks to identify the underlying states of a system from observable outputs, to determine classes of behaviour from repetitive dives.

Repeated Vessel Interactions and Climate- or Fishery-Driven Changes in Prey Density Limit Energy Acquisition by Foraging Blue Whales

Blue whale survival and fitness are highly contingent on successful food intake during an intense feeding season. Factors affecting time spent at the surface or at depth in a prey patch are likely to

Predator–prey interactions and climate change

Climate change will affect species more through shifts in ecosystem functioning than by its direct effect (Rand and Tscharntke, 2007; Tylianakis et al. 2008), and complex networks of biotic interactions include compensatory mechanisms that may buffer the effects of climate change on species.



Weight loss during breeding is adaptive for female macaroni penguins, Eudyptes chrysolophus

Natural selection should produce females that sacrifice their own condition to meet the increasing demands of their chicks, and it is predicted that females will endure the cost of travelling further from the nest to obtain a more predictable meal of krill.

Diet and reproductive success of Adélie and chinstrap penguins: linking response of predators to prey population dynamics

The diet and reproductive performance of two sympatric penguin species were studied at Signy Island, South Orkney Islands and suggested that the abundance of krill may have fallen below the level required to support normal breeding success of penguins sometime before or during the 2000 breeding season.

Are penguins and seals in competition for Antarctic krill at South Georgia?

The hypothesis that the increased fur seal population at South Georgia may have resulted in greater competition for the prey of macaroni penguins, leading to the decline in their population is tested.

Foraging performance and reproductive success of Humboldt penguins in relation to prey availability

It is concluded that due to physiological and morphological constraints the penguins at Pan de Azucar could not increase diving effort to compensate for lower prey availability, but took extended foraging trips instead, resulting in less chick growth and lower reproductive success.

Diet, provisioning and productivity responses of marine predators to differences in availability of Antarctic krill

The results show a coherent, though complex, pattern of within and between species similarities and differences that mainly reflect the degree of dependence on krill, the feasibility of taking alternative prey and constraints on trip duration and/or meal size imposed by foraging adaptations.

Seasonal and interannual variation in foraging range and habitat of macaroni penguins Eudyptes chrysolophus at South Georgia

In marine ecosystems, characterisation of the foraging areas and habitats of predators is a key factor in interpreting their ecological role, We studied the foraging areas of the macaroni penguin


The chick-rearing period of both Macaroni Penguins Eudyptes chrysolophus and Rockhopper Penguins E. chrysocome at Marion Island was 70 days and chicks of both species each received approximately 30 meals, each meal representing one parental foraging trip.

Increases in Antarctic penguin populations: reduced competition with whales or a loss of sea ice due to environmental warming?

There is a need to pay close attention to environmental data in the management of Southern Ocean resources given the complexity of relating biological changes to ecological perturbations.

Provisioning behaviour of macaroni penguins Eudyptes chrysolophus

It is shown that Macaroni Penguins Eudyptes chrysolophus have clear sex-specific differences in provisioning behaviour, which appears to relate to a threshold rate governing whether or not chicks survive.

A Predator's Perspective on Causal Links Between Climate Change, Physical Forcing and Ecosystem Response

It is proposed that krill longevity should be incorporated into models that seek to identify and understand causal links between climate change, physical forcing and ecosystem response in the western Antarctic Peninsula region.
