On 19th of June, the world comes together to celebrate World Albatross Day, an annual event dedicated to raising awareness about these magnificent seabirds and the conservation challenges they face. World Albatross Day serves as a crucial platform to educate and inspire action to protect these iconic ocean wanderers. With their graceful flight and important ecological role, albatrosses deserve our attention and concerted efforts for their survival.
South Africa is a long-standing Party to the International Agreement on the Conservation of Albatrosses and Petrels (ACAP). The agreement was brought into existence on 1 February 2004. The day also falls on the date of the signing of the Agreement 22 years ago. ACAP has chosen the theme “Plastic Pollution” to mark the fourth World Albatross Day, to be celebrated on 19 June 2023. This follows the inaugural theme “Eradicating Island Pests” in 2020, “Ensuring Albatross-friendly Fisheries” in 2021, and “Climate Change” last year in 2022.
Albatrosses close to home
Multiple species of albatross are found across the Southern Ocean. This includes Antarctic, sub-Antarctic and subtropical waters. These albatrosses breed on sub-Antarctic and Antarctic islands including South Africa’s sub-Antarctic Marion Island. Marion Island holds significant breeding populations of four albatross species – the Wandering Diomedea exulans, Grey-headed, Light-mantled Phoebetria palpebrata and Sooty Phoebetria fusca. In addition to this, two other species of albatrosses have been seen ashore on Marion Island – Black-browed and Indian Yellow-nosed Thalassarche carteri. To read more about the “other” two species of albatrosses recorded from Marion Island as uncovered by one of our researchers Kim Stevens, click here.
The Challenges Facing Albatrosses
Albatrosses face a range of challenges that threaten their survival. One of the most pressing issues is longline fishing, where albatrosses can become accidentally caught on fishing hooks, leading to injury or death. Pollution, habitat destruction, climate change, and invasive species on breeding islands also pose significant risks to their populations. World Albatross Day sheds light on these challenges and promotes measures to mitigate their impact. The pressing threats to Albatrosses in the Southern Ocean include invasive species on breeding islands, most notably, the house mice on Marion Island. Introduced to Marion Island by sealers in the early 19th century, the house mice have been inflicting devastating impacts on the ecology of the island, including killing its native seabirds.
Conservation Efforts and Awareness
The Mouse-Free Marion Project is a registered non-profit company in South Africa, established to eradicate the invasive albatross-killing mice on Marion Island. The project was initiated by BirdLife South Africa and the South African Department of Forestry, Fisheries and the Environment (DFFE). Upon successful completion, the project will restore the critical breeding habitat of over two million seabirds, many globally threatened, and improve the island’s resilience to a warming climate. For more information or to support the project please visit mousefreemarion.org.
May 2023: Barbara Creecy, Minister of Forestry, Fisheries, Forestry and the Environment, confirms government support for the Mouse-Free Marion Project in her budget speech.
What can you do?
In keeping with this year’s theme for World Albatross Day “Plastic Pollution”, as an individual you can participate by reducing plastic pollution, organising or joining local beach cleanups, where you can help remove litter and prevent it from reaching the oceans, including minimising the use of single-use plastics. Education plays a vital role in driving positive change for albatross conservation. Increase your understanding of albatross biology, their unique adaptations, the threats they face, and the ecological importance they hold in marine ecosystems by reading some of these selected publications here. By raising awareness and fostering partnerships, we can work collectively to safeguard albatross populations and their habitats.
Let us unite in our efforts to protect these majestic ocean wanderers and ensure a future where albatrosses continue to grace our oceans for generations to come.

The Mouse-Free Marion Project is a partnership between the Department of Forestry Fisheries and the Environment (DFFE) and BirdLife South Africa, working towards an operation to eradicate invasive mice from Marion Island.
The mice, which were introduced accidentally some 200 years ago, have caused great harm to the ecology of Marion Island. They feed on indigenous invertebrates, damage vegetation, and have more recently started eating seabird chicks. As a result, the mice are considered to be a major pest to the island. If they are not removed, the ecosystem of the island will continue to deteriorate, and they will likely cause most of the seabirds on the island to become locally extinct. These seabirds will be lost to the island forever.
In order to monitor how the island recovers after the mice have been removed, we are collecting data on aspects of the island that we expect to improve once the mice are gone. These include the vegetation and invertebrates. Colleagues working on other projects are collecting similar data on seabirds.
The reason why it is important to collect this data before the eradication operation is so that we can compare and monitor how the island changes (improves) as a result of the eradication operation – comparing the island’s vegetation and invertebrate features before and after the operation.
More about your plans for this takeover?
The project will make use of data that have already been collected over many years, primarily through the various long-term monitoring projects that have been undertaken at Marion Island over many years. The focus of our work currently is to fill some pre-eradication (baseline) data on vegetation and invertebrates. This particular work was initiated during the 2022/23 period, and will continue in 2023/24. The takeover period will be used to provide training and orientation to the new Marion80 overwintering team member (Camilla Smyth) and for the current Marion79 Mouse-Free Marion overwintering team member (Elsa van Ginkel) to hand over the field-work responsibilities to Camilla.
The work includes standard invertebrate and vegetation survey techniques to establish a baseline that can be used to monitor how these ecological parameters change following the eradication of invasive mice. These surveys will repeat and build on historical surveys that have been undertaken on the island previously.
We will also be undertaking further bait trials and weather monitoring to help inform the planning of the baiting operation.

World Wetlands Day, is celebrated every year on 02 February. On this day, in 1971, the Convention on Wetlands of International Importance (Ramsar Convention) was signed in Ramsar, Iran.
World Wetlands Day is celebrated to to “raise awareness and understanding of what wetlands are and how we can contribute towards restoring them through making conscious choices, becoming persuasive voices and taking bold actions” (read more here).
What is a wetland?
A wetland is defined as the land which is transitional between terrestrial and aquatic systems where the water table is usually at or near the
surface, or the land is periodically covered with shallow water, and which land in normal circumstances supports or would support vegetation typically adapted to life in saturated soil (1).
Why is wetland restoration so important? Listed below are a few benefits of wetland restoration:
- Enhanced biodiversity
- Improve water supply
- Store carbon
- Reduced impacts from flooding
- Improve livelihoods
- Enhance well–being
- Protection of agricultural resources (1; 2)
Is your role in wetland restoration important?
Yes! Our individual and collective actions have an impact (1).
What can you as individual do to help protect and preserve wetlands?
- Participate in programs that help protect and restore wetlands.
- Report illegal actions such as unauthorized wetland fill or dredging activities to government authorities
- Pick up litter and dispose in appropriate trash containers. Keep surface areas that wash into storm drains clean from pet waste, toxic chemicals, fertilizers and motor oil, which can eventually reach and impair our wetlands.
- Use native species when planting trees, shrubs and flowers to preserve the ecological balance of local wetlands.
- Avoid wetland when you are expanding your house.
- Use phosphate-free laundry and dishwasher detergents. Phosphates encourage algae growth, which can suffocate aquatic life.
- Use non-toxic products for household cleaning and lawn and garden care. Never spray lawn and garden chemicals outside on a windy day or on a day that it might rain and wash the chemicals into waterways.
- Enjoy the scenic and recreational opportunities wetlands offer, while preserving their integrity for future generations by minimizing the use of heavy equipment and staying in designated visitor areas where available (3).
Did you know that the South African Prince Edward Islands (Prince Edward Island and Marion Island) is declared as Wetland of International Importance?
The Prince Edward Islands was declared Wetland of International Importance: Ramsar Site No.1688, on 22 May 2007. The conservation and management of this site falls within the responsibility of the Directorate: Southern Oceans and Antarctic Support of the Department of Forestry, Fisheries and the Environment.

Ecosystem processes are changing worldwide, especially with the impacts of invasive species being exacerbated by climate change. 
This is particularly obvious in the Southern Ocean where a warmer and dryer environment allows the proliferation of species once limited by the cold climate. South African Special Nature Reserve, Marion Island is no exception. A recent proliferation of invasive House Mouse attacks on endangered breeding seabirds suggests a profound alteration of the natural ecosystem. This has led to the planned eradication of mice at Marion Island in winter 2023.
For the next three years, the new SANAP project co-led by Dr Maëlle Connan (Research Fellow in the Marine Apex Predator Research Unit, Nelson Mandela University) and Prof. Peter Ryan (director of the FitzPatrick Institute of African Ornithology – University of Cape Town) will focus on three data deficient species of avian scavengers: Black-faced Sheathbill, Kelp Gull and Brown Skua.
By focusing on these three species and some of their prey, the project intends first to fill identified scientific gaps that are crucial for best planning of the mouse eradication. Second, these three scavengers will be used as indicators of recovery of the terrestrial ecosystem post-eradication by establishing baselines for the scavenger guild and their prey against which the impact of a successful mouse eradication can be measured in years to come. (Above: Left – Maelle Connan, Right – Peter Ryan)

An important aspect of the project will entail conducting regular censuses and seasonal round island counts in addition to behavioural observations of the focal scavenger species. Indeed, the three species to be studied are at the top of the terrestrial food chain, and thus can be used as indicators of recovery of the island biota post-eradication.
On one hand, Black-faced Sheathbills and Kelp Gulls used to predate on terrestrial invertebrates, at least seasonally, but this behaviour has decreased in sheathbills as invertebrate populations have collapsed through mouse predation. There are no recent data for Kelp Gulls. On the other hand, many pairs of Brown Skuas predate mainly on burrowing petrels, thus will inform on the recovery of these nocturnal species from mouse predation. The skua data will be complemented by the implementation of an automated acoustic monitoring to detect the presence and coarse distribution of the most elusive and cryptic nocturnal species which are notoriously difficult to study. (Left – Eleanor Weideman in the field on Marion Island.)
Data obtained during the project will be swiftly shared to the Mouse-Free Marion programme manager Dr Anton Wolfaardt, to ensure updated information is available for the best planning of the mouse eradication.

Marion Island (29 000 hectares) and Prince Edward (4500 hectares), collectively known as the Prince Edward Islands (PEIs) were annexed by South Africa in December 1947 and January 1948, respectively. Since then, South Africa has maintained a research and weather station on Marion Island, Prince Edward remains uninhabited. The PEIs were declared a Special Nature Reserve in 1995, a Ramsar Wetland Site of International Importance in 2007 and the surrounding waters a Marine Protected Area in 2009. The islands, governed by a suite of national environmental legislation under the Prince Edward Islands Management Plan (which includes a plan for the control and eradication of invasive alien species), are managed by the Oceans and Coasts Branch of the Department of Forestry, Fisheries and the Environment (DFFE) as the designated Management Authority under the National Environmental Management Protected Areas Act 57 of 2003.
The House Mouse Mus musculus (Photo Credit: Stefan Schoombie), inadvertently introduced to Marion Island by sealers in the early 1800s, successfully established on the island. With the human occupation of the island in 1948, four cats were brought to the island to control the mice in and around the station. However, these cats bred on the island, with their offspring becoming feral, and by the 1970s the population had increased to about 2000 individuals that were killing some 450 000 birds per year, mostly chicks of burrow-nesting species.
With South Africa’s successful eradication of the cats in 1991 (confirmed in 1992), until recently the largest island upon which this has been achieved, the mice continued to thrive and over the years have had devastating effects on Marion’s fragile ecosystem by negatively affecting invertebrate densities, impacting on the vegetation by consuming seed loads and preying upon the chicks of burrowing petrels (since the 1980s) and surface-breeding albatrosses (since 2003), with ‘scalpings’ occurring from 2009 and attacks on adult birds recorded more recently in 2019.

Marion Island supports some 25% of the world’s breeding population of Wandering Diomedea exulans, 12% of Sooty Phoebetria fusca and 7% of Grey-headed Thalassarche chrysostoma Albatrosses and smaller percentages of Light-mantled Albatrosses P. palpebrata and Grey Petrels Procellaria cinerea. It is clear something needs to be done or the severe impact of the mice could result in critical impacts on global populations and in the extirpation of up to 18 of the 27 bird species found on Marion within the next 30 to 100 years.

In what would later become a partnership with DFFE, a Feasibility Study and Risk Assessment, undertaken in 2016 by John Parkes on behalf of BirdLife South Africa (BLSA), indicated that eradication was indeed possible. Also funded by BLSA, Draft Project and Operational Plans to eradicate mice on Marion Island were subsequently developed in 2018 by New Zealand eradication expert, Keith Springer, following an island visit. DFFE has been working closely with the UK’s Royal Society for the Protection of Birds (RSPB) over the last few years in support of the Gough Island Restoration Programme (GIRP) which aims to eradicate House Mice on Gough during June to September 2021. For more information and the latest updates on the GIRP, please visit: https://www.goughisland.com
On 12 May 2020, a Memorandum of Understanding (MoU) for the Mouse-Free Marion (MFM) Project was signed between DFFE and BLSA. Subsequently, a MFM Management Committee was established to initiate the development of the project and the two MoU partners are now working closely, together with various experts and institutions (including those involved with successful operations on other islands), on the detailed planning on all operational aspects required for the execution of this complex and costly project.
The MFM Project will make use of internationally agreed best-practice approaches to eradicate mice from the island. The Feasibility Study and draft Project and Operational Plans highlight that the only methodology offering any chance of success on an island of the size and topography of Marion Island is aerial spreading of bait containing a rodenticide with a proven capacity to eradicate mice. 
The systematic aerial sowing of bait will be conducted by GPS-guided helicopters with underslung bait buckets to ensure every single mouse territory is covered. The aerial baiting will be complemented by hand-baiting approaches in and around the base and other infrastructure on the island. If a single pregnant female is not targeted, it could result in the failure of the entire operation, but if it works, Marion Island will be by far the largest island in the world from which House Mice have successfully been eradicated.
Time window trade-offs have been assessed and it has been determined that winter (April/May – August/September) is the optimal period in which to implement an eradication operation. This is the non-breeding period for mice at Marion, when their population size is low and natural food resources are minimal, rendering bait more attractive. A winter-baiting operation also reduces the risks to non-target seabird species on the island, as many are not resident on the island during the winter months.
Currently, the eradication exercise is planned for the austral winter of 2023 and, to review and update the Project and Operational Plans, a Project Manager (Dr Anton Wolfaardt – photo left) and an Operations Manager (Mr Keith Springer – photo right) have been appointed.
A project of this nature requires substantial funding. To date, funds provided and committed are comprised largely of donations, government funding and crowd sourcing to save Marion Island’s seabirds.
