Every year on 19 June, World Albatross Day raises awareness of one of the world’s most remarkable seabird groups and the challenges they face in an increasingly changing environment. With their extraordinary wingspans, ocean-crossing migrations and critical role in Southern Ocean ecosystems, albatrosses are among the most iconic ambassadors of the Antarctic and sub-Antarctic regions.
For South Africa, Marion Island in the Prince Edward Islands archipelago is one of the world’s most important breeding sites for albatrosses. The island supports breeding populations of Wandering, Grey-headed, Indian Yellow-nosed, Sooty and Light-mantled Albatrosses, making it a globally significant refuge for these majestic seabirds. Protecting these species is central to the South African National Antarctic Programme’s (SANAP) vision to understand, develop and conserve the Antarctic and Southern Ocean environment for present and future generations.
Through SANAP-supported research, South African scientists are advancing our understanding of how environmental change is affecting seabirds and the ecosystems on which they depend. Professor Susan Cunningham of the University of Cape Town leads research investigating the on-island impacts of climate change on the Southern Ocean’s iconic seabirds. Her work examines how changing temperatures, rainfall patterns and ecosystem dynamics influence breeding success, behaviour and long-term population trends of seabirds, including albatrosses.
Complementing this work, Azwianewi Benedict Makhado of the Department of Forestry, Fisheries and the Environment (DFFE) is investigating the interactive effects of multiple stressors and environmental change on seabird breeding performance. This research seeks to understand how climate variability, food availability and other environmental pressures combine to affect breeding success and population resilience in seabird species that depend on the Southern Ocean.
A major conservation milestone for albatrosses and other seabirds has been the implementation of the Mouse-Free Marion Project. Introduced house mice have caused severe impacts on Marion Island’s bird populations, attacking chicks and threatening the survival of several seabird species, including albatrosses. The ambitious eradication initiative aims to remove invasive mice from the island and restore the ecological balance of this globally important seabird sanctuary. A successful mouse eradication programme will significantly improve breeding success and long-term survival prospects for albatrosses and many other native species.
The conservation of albatrosses extends far beyond Marion Island. These birds spend most of their lives traversing vast oceanic distances, linking continents and ecosystems across the Southern Ocean. Their health and survival provide valuable insights into the condition of marine ecosystems and the impacts of environmental change. On this World Albatross Day, SANAP celebrates the dedication of researchers, conservation practitioners and support teams working to safeguard these magnificent birds. Through science, collaboration and conservation action, SANAP continues to contribute to a future where albatrosses can thrive in healthy Southern Ocean ecosystems.
As we commemorate World Albatross Day 2026, we are reminded that protecting albatrosses means protecting the Southern Ocean itself—an ocean that sustains biodiversity, regulates the global climate and connects us all.

Macaroni Penguin: The Macaroni penguin is one of the most abundant penguin species studied within SANAP-supported regions, including Marion Island. Recognisable by its striking yellow-orange crest, this species forms vast breeding colonies that can number in the millions, offering researchers unique opportunities to study population dynamics and ecosystem interactions. Feeding primarily on krill and small marine organisms, macaroni penguins are also impressive divers, capable of reaching depths of up to 100 metres. SANAP researchers monitor their breeding success and foraging behaviour to better understand the health of subantarctic marine ecosystems.
Emperor Penguin: The Emperor penguin, the largest of all penguin species, is a true symbol of Antarctic resilience. Although primarily found on mainland Antarctica rather than Marion or Gough Island, SANAP-affiliated research contributes to broader Antarctic ecosystem studies that include this iconic species. Adapted to survive extreme temperatures as low as −60°C, emperor penguins exhibit remarkable breeding behaviour, with males incubating eggs on their feet during the harsh winter months. Their ability to dive to depths exceeding 500 metres continues to fascinate scientists studying physiological adaptation and survival in extreme environments.
King Penguin: The King penguin is a prominent feature of Marion Island’s wildlife and a key focus of SANAP research. With their distinctive orange neck patches and large body size, king penguins form dense breeding colonies that provide valuable data on population trends and climate variability. Notably, they have the longest breeding cycle of any penguin species, lasting over a year, which makes them particularly sensitive to environmental changes. Researchers on Marion Island closely track their foraging patterns and breeding success to assess shifts in ocean conditions and prey availability.
Rockhopper Penguin:The Rockhopper penguin, known for its energetic movements and spiky yellow crest, is a charismatic species found on Marion Island and other subantarctic locations. Its name comes from its habit of hopping across rocky terrain, often breeding on steep slopes that challenge both the birds and the researchers studying them. SANAP teams monitor their populations closely, as rockhopper penguins are considered vulnerable to environmental pressures. Their diet of krill, squid, and crustaceans links them directly to ocean health, making them important indicators in marine research.
Adélie Penguin: The Adélie penguin is a classic Antarctic species commonly found along the icy coastline. While not resident on Marion or Gough Island, it remains an important part of SANAP’s broader Antarctic research scope. Easily identified by the white ring around its eye, the Adélie penguin builds pebble nests on rocky ground and relies heavily on krill as a food source. Long-term monitoring of Adélie populations helps scientists understand the impacts of sea ice changes and climate variability on Antarctic ecosystems.
The accompanying infographic can also serve as a useful educational tool for learners, helping children engage with these remarkable species in their school projects.

Guardians of the Sub-Antarctic: The Prince Edward Islands — comprising Marion Island and Prince Edward Island — are globally significant biodiversity hotspots, they host thriving populations of seabirds and marine mammals, including King, Macaroni, Gentoo, and Rockhopper penguins, several Albatross and Petrel species, Southern Elephant seals and Antarctic Fur seals and Killer whales. SANAP-supported researchers monitor wildlife populations to detect changes linked to climate variability, ocean conditions, and human impacts. Long-term datasets collected over decades allow scientists to track breeding success, foraging behaviour, migration patterns, and survival rates.
These islands are also a Special Nature Reserve — South Africa’s highest level of environmental protection — ensuring strict conservation management. Ongoing efforts include the monitoring ecosystem health, studying predator-prey relationships, investigate the effects of climate change on sub-Antarctic food webs and managing invasive species. The eradication of invasive species and strict biosecurity controls are among conservation projects that protect these fragile ecosystems from human-introduced threats.

19 June 2025 marks World Albatross Day, a global celebration of these magnificent seabirds whose wide wingspans and far-ranging flight paths have long captured the imagination of sailors, scientists, and nature lovers alike. For South Africa, and particularly for the South African National Antarctic Programme (SANAP), this day highlights not only the beauty and ecological importance of albatrosses—but also the urgent need to protect them.
At the heart of SANAP’s commitment to seabird conservation is ongoing research and monitoring on Marion Island, one of the two Prince Edward Islands in the Southern Ocean. Marion Island is home to several albatross species, including the iconic Wandering Albatross, known for having the largest wingspan of any bird in the world. These seabirds are critical indicators of ocean health, and their survival is closely linked to the stability of sub-Antarctic ecosystems.
SANAP scientists have been conducting long-term ecological studies on albatross population trends, breeding behaviour, and foraging ecology, using tracking devices and direct observation to better understand how climate change, ocean dynamics, and human activities are impacting these vulnerable birds.
A major step in protecting Marion Island’s seabirds is the Mouse-Free Marion Project—a large-scale conservation effort aimed at eradicating invasive house mice that prey on albatross chicks and other native birds. These mice, unintentionally introduced by humans, have developed aggressive predatory behaviours that threaten the survival of not only the Wandering Albatross but also Grey-headed, Sooty, and Light-mantled Albatrosses, as well as burrowing petrels and other island species. The Mouse-Free Marion project represents one of the most important island restoration initiatives globally, and a critical investment in the long-term survival of South Africa’s seabird populations. Success will mean a safer future for generations of albatrosses nesting on this remote and windswept island.
This World Albatross Day, we celebrate the tireless work of scientists, conservationists, and partners who are helping to give these majestic ocean wanderers a fighting chance. Let’s continue to raise awareness and support efforts to keep the skies above the Southern Ocean filled with soaring wings.

Every year on April 25th, we celebrate International Penguin Day—a global reminder of the unique role penguins plays in our planet’s ecosystems. These birds are not just symbols of the icy South—they are indicators of ocean health and climate change. From the sub-Antarctic islands to the Antarctic continent itself, penguins serve as sentinels of the sea, helping scientists track environmental shifts that affect us all.
South Africa plays a vital role in this mission through its National Antarctic Programme (SANAP), which supports long-term ecological research at key sites such as Gough Island, Marion Island, and Antarctica. These research stations are crucial hubs for studying penguin populations like the Northern Rockhopper on Gough Island and the Macaroni penguins on Marion Island. Scientists monitor breeding patterns, foraging behaviour, and survival rates—data that provide early warnings about oceanic changes. In Antarctica, SANAP researchers study Adélie and Emperor penguins, whose survival is intimately tied to the health of sea ice and krill populations.
By investing in these research efforts, South Africa not only contributes to global conservation science but also highlights the importance of protecting our shared polar heritage. This International Penguin Day let’s celebrate the science that keeps these beloved birds waddling into the future.
