 John Dickens (British Antarctic Survey, Cambridge, United Kingdom) and colleagues have published open access in the journal Frontiers in Marine Science on using drones (UAVs) in monitoring albatrosses, penguins and seals on sub-Antarctic islands in the South Atlantic.  “A total of nine islands, historically recorded as breeding sites for wandering albatross, were surveyed with 144 fledglings and 48 adults identified from the aerial imagery”.

The paper’s abstract follows:

“Many remote islands present barriers to effective wildlife monitoring in terms of challenging terrain and frequency of visits. The sub-Antarctic islands of South Georgia and the South Sandwich Islands are home to globally significant populations of seabirds and marine mammals. South Georgia hosts the largest breeding populations of Antarctic fur seals, southern elephant seals and king penguins as well as significant populations of wandering, black-browed and grey-headed albatross. The island also holds important populations of macaroni and gentoo penguins. The South Sandwich Islands host the world’s largest colony of chinstrap penguins in addition to major populations of Adélie and macaroni penguins. A marine protected area was created around these islands in 2012 but monitoring populations of marine predators remains a challenge, particularly as these species breed over large areas in remote and often inaccessible locations. During the 2019/20 austral summer, we trialled the use of an unoccupied aerial vehicle (UAV; drone) to monitor populations of seals, penguins nd albatross and here we report our initial findings, including considerations about the advantages and limitations of the methodology. Three extensive southern elephant seal breeding sites were surveyed with complete counts made around the peak pupping date, two of these sites were last surveyed 24 years ago. A total of nine islands, historically recorded as breeding sites for wandering albatross, were surveyed with 144 fledglings and 48 adults identified from the aerial imagery. The UAV was effective at surveying populations of penguins that nest on flat, open terrain, such as Adélie and chinstrap penguin colonies at the South Sandwich Islands, and an extensive king penguin colony on South Georgia, but proved ineffective for monitoring macaroni penguins nesting in tussock habitat on South Georgia as individuals were obscured or hidden by vegetation. Overall, we show that UAV surveys can allow regular and accurate monitoring of these important wildlife populations.”

Marine ornithologists and conservationists around the world are supporting the Mouse-Free Marion Project

To date, 813 sponsors have funded 2260 hectares towards the eradication of Marion Island’s albatross-killing mice with donations exceeding two and a quarter million South African Rands.  Whereas this represents a larger area than that of New Zealand’s Antipodes, the most recent sub-Antarctic island to be rid of its introduced mice, at some 30 000 ha Marion will be the largest island by far where a mouse eradication will be attempted in a single operation.  So there’s a long way still to go before the projected 2023 eradication will be fully funded!

The majority of the sponsorships has come from within South Africa.  However, a so far small but a growing number has come from outside the country, showing that the eradication of the island’s mice and the plight of its embattled albatrosses and petrels has struck a chord worldwide.  Among this international fraternity are researchers and conservationists who have worked with albatrosses and their petrel kin.  The Mouse-Free Marion Project is most grateful for their support and reached out to seven of these generous people to learn more about what motivated them to donate.

Christine Bogle, a New Zealander currently based in Australia, is the ACAP Executive Secretary.  She wrote in an ACAP media release last year: “The inaugural World Albatross Day comes at a time when the world has been turned upside down by a global pandemic.  I hope this crisis reminds us how much we must treasure the natural environment of which we are custodians. To paraphrase the words of Sir Geoffrey Palmer (former New Zealand Prime Minister), who in May 1990 was speaking about whales, if we allow albatrosses to become extinct, how can we imagine ourselves capable of solving the many other environmental problems the world faces?”

“Nobody wants to kill a magnificent 50-year-old albatross and yet hundreds are killed every day just to put fish on your plate” is the view of Australian Nigel Brothers, Seabird Consultant with Humane Society International who has worked with seabirds and their introduced (but now eradicated) predators on Macquarie Island.  He currently serves as an expert member on ACAP’s Seabird Bycatch Working Group.  Read more about Nigel’s support of the MFM Project here.

 Jaimie Cleeland (photograph at top) conducted her PhD research on Macquarie Island’s albatrosses ovrer 2011 to 2014, followed by a year on Gough Island working with the Critically Endangered Tristan Albatross Diomedea dabbenena.  Currently with the Australian Antarctic Division, she writes: “Albatrosses are long lived, have a prolonged juvenile stage, breed infrequently and have strong pair bonds which they can maintain for life.  This slow life cycle makes them vulnerable to threats such as industrial fishing, invasive predators and marine pollution”.

Chris Robertson QSM*, a now-retired New Zealander biologist, is a doyen of albatross research, well known to marine ornithologists.  He writes “After more than 50 years working with the albatross kingdom in the field, upon the autopsy table, and in more than 70 museum collections, I am continually surprised at the steady advances in our understanding of the species uniqueness and behaviour of these pre-eminent avian marine travellers and predators.  I have been privileged to assist in New Zealand’s improving fisheries bycatch mitigation and successful introduced mammal removals from islands.  All albatross islands are the necessary breeding places which will ensure their survival.  Any project which cleans their habitat and reduces their mortality on land or at sea, deserves all our unconditional support”.

“Albatrosses are one of the pinnacles of evolution in harnessing the winds to search much of the world’s oceans for food.  Sadly, human activities are putting them at risk of extinction” is the considered view of Mark Tasker, retired Head of Marine Advice, Joint Nature Conservation Committee, United Kingdom; past Chair and Vice Chair of ACAP’s Advisory Committee; and currently Convenor of the ACAP Taxonomy Working Group.  Read about Mark’s generous 25-ha sponsorship here.

Hawaii bans the release of albatross-killing balloons

 Black footed Albatross and balloon

ACAP Latest News has reported on numerous times of albatrosses and petrels ingesting or becoming entangled by helium-filled balloons that had been released in the open air and subsequently returned to earth or sea after bursting (click here).  Unless successfully treated by rehabilitation centres it seems many of the affected birds will have succumbed.   Around the world various NGOs and social media groups have been working assiduously to persuade local, regional or national authorities to ban, or at least limit, the intentional outdoor release of lighter-than-air balloons, with it is fair to say, limited results (for example Balloons Blow and Save Queensland from Balloons).

Significant news then that on 30 June the State of Hawaii banned (as from 1 January 2023, 18 months away) the intentional release of all balloons outside (with the exceptions of hot air, meteorological and research balloons).  “Sea turtles, albatrosses and other marine life that eat squid and jellyfish can mistake balloons in the ocean for food.  This is due to the tentacle like appearance of the plastic ribbons and the balloons which undergo brittle fracture in the air when they burst.  When ingested, balloons become sticky and gooey and are impossible for an animal or bird to move through their digestive system.  Blockages of the gastro-intestinal tract caused by balloons leads the animal or bird to starve to death.  The plastic ribbons attached to balloons are also a danger as they can cause injury or death to marine life that become entangled in them or ingest them” (click here).

It remains to be seen whether Hawaii’s lead will be copied by other states in the USA, or in other parts of the world where balloons have been reported leading to the death of albatrosses and petrels.  However, it seems the pressure groups will continue to work towards more bans.

“Tristan Albatross falling through gaps in protection on High Seas”

Tristan Albatross Michelle Risi Maureen Rousseau

The follows news item is taken in its entirety from BirdLife International’s website.  It has been written by Oli Yates, Head of BirdLife’s Marine Programme.

“With a new protected area and a campaign to remove invasive mice, there have been many recent advances in the conservation of this Critically Endangered albatross. But our work isn’t over yet. Discover the measures in place to safeguard the species – and the gaps that still need to be filled.

The Tristan Albatross Diomedea dabbenena (Critically Endangered) is one of the great albatrosses, ranging widely across the South Atlantic and into the Indian Ocean. These birds feed on fish and squid in surface waters, returning to their nest sites every second year where eggs are laid in January, hatch in March-April and fledge eight to nine months later from around November.

Almost the entire global population of Tristan Albatross nest at Gough Island, an incredibly remote island in the middle of the South Atlantic – the most southerly of the Tristan da Cunha island group, on the very edge of the strong westerly winds known as the ‘roaring forties’. This UNESCO Natural World Heritage site is perfectly placed, if you’re an albatross, with year-round windy conditions, highly productive waters of the Tristan da Cunha Exclusive Economic Zone within immediate reach, and roughly equidistant between the continental shelves of South America and southern Africa.  

The small community at Edinburgh of the Seven Seas, the settlement at Tristan da Cunha,  have recently made a huge contribution to marine conservation by designating a Marine Conservation Zone across almost 700,000 km2 of their Exclusive Economic Zone. This ‘no-take zone’ excludes fishing in most areas, with low-impact sustainable fishing permitted around the islands and seamounts to ensure the islanders can maintain economic and food security. The people of Tristan da Cunha have given the world one the biggest sanctuaries for wildlife.

Gough Island would be the perfect habitat, but for the house mice which were accidentally introduced decades ago by visiting ships. Over time, the mice learned to exploit the young chicks of albatrosses and petrels, which have no natural defence against the mammalian threat. The mice are now estimated to account for the loss of over two million seabird eggs and chicks each year. This ghastly reality has ravaged the Tristan Albatross population, and now recent evidence shows the killer mice are able to devour the adult birds too. An incredible project is underway to eradicate these non-native mice from the island - one of the world's most challenging island restoration projects – which would restore the fortunes of the island's birds.

Increased protection for this Critically Endangered species is coming on in leaps and bounds at the breeding site and its surrounding waters. This improved protection is also reinforced by vital improvements in fishery management in the Benguela Current, where seabird deaths in the Namibian demersal longline fishery have been reduced by 98%, and in the South Africa hake trawl fishery by 90%. That equates to over 30,000 birds saved every year.

Despite these stunning advances, observers on Asian distant water tuna fishing vessels continue to report accidental ‘bycatch’ of Tristan Albatrosses in areas managed by the International Commission for the Conservation of Atlantic Tunas on the High Seas, outside the Tristan Marine Protected Zone.

The RSPB (BirdLife in the UK) runs a monitoring programme for Tristan Albatrosses on Gough Island. Fledgling and adult Tristan Albatrosses receive unique leg rings, so that the population can be monitored and understood over time. In the last year three rings from adult Tristan Albatrosses have been recovered by fisheries observers, indicating fishing vessels are likely not using the seabird bycatch prevention measures they are required to deploy. When used correctly, the mitigation measures (weighting the fishing lines, setting them at night and adding and brightly-coloured ‘bird-scaring lines’), are highly effective at reducing bycatch to negligible levels.

The around 95% of distant water fishing vessels do not carry observers. In order to enforce mandatory conservation measures, we need much stronger monitoring, a greater number of observers and the use of electronic monitoring technology. These remain key pieces of the puzzle to ensure the survival of these magnificent birds.”
