Following the completion of the bait drop on Gough Island in August this year, things started to look good for the island and its wildlife, especially its breeding seabirds, with no signs of introduced House Mice that had been wreaking devastation among both surface-nesting and burrowing seabird chicks.  Critically Endangered and near endemic Tristan Albatrosses Diomedea dabbenena had stopped having their chicks eaten alive in two study colonies, winter-breeding Endangered and endemic Atlantic Petrels Pterodroma incerta had done well (breeding success of 63%) after years of very low success due to mice predation, and the land birds taken into temporary captivity to avoid non-target poisoning had all been successfully released back into the wild.

Sad news then to read this week that a trail camera has picked up the image of a surviving mouse, putting the whole eradication attempt into jeopardy., A press release by the UK’s Gough Island Restoration Programme (GIRP) follows in its entirety.

“Today, Tuesday 14 December, the Gough Island Restoration Team is devastated to report that following the mouse eradication attempt earlier this year, a single mouse has been spotted via monitoring equipment on the island.

We are deeply upset by this news and know that the many people who supported us in our endeavour to restore the island will be equally saddened. It matters because the removal of every mouse from Gough Island was necessary to prevent the loss of more than 2 million seabird chicks and eggs each year and to protect endangered species like the Tristan albatross from extinction.

Beccy Speight, chief executive of the RSPB said: “This was one of the most ambitious island restoration programmes ever attempted, bringing together experts from around the world to protect globally endangered seabirds in what many would consider one of the most remote and difficult to reach locations on Earth. With over a decade of planning and given the logistics involved, this has been the conservation equivalent of landing on the Moon.

“We needed to take this urgent action to save millions of eggs and chicks from predation, prevent extinctions and to undo the damage caused by mice which humans unwittingly allowed onto the island in the past. We are confident that through this partnership we put everything in place to give the project the best chance of being successful. Although only one mouse has been sighted so far, unfortunately experience would tell us that it is unlikely to be the only one.

“Although it appears we have fallen short of our target, it is too early to know what this means or just how much time we might have bought the seabirds of Gough. We are continuing to monitor the island and assess the situation. The situation at Gough and threat to the unique seabirds of this island only serve to underline the importance of effective biosecurity measures on currently predator-free islands to prevent invasive species arriving in the first place and devastating native wildlife, and the need for island restoration projects to protect affected species from extinction.”

More details come from GIRP Programme Executive, Andrew Callender:

“The RSPB Overwintering Team has been monitoring for signs of mice since the eradication team demobilised off Gough Island in mid-August.  We are deeply concerned to report that on 11th December, a single mouse was recorded on one of the camera traps around 260 meters from Base – the team retrieved this camera on December 13th.  There has to date been no other sign of mouse activity.  We will continue to gather what evidence we can to ascertain the scale of survival and any breeding activity and are responding accordingly."

ACAP Latest News will continue to report on developments on Gough Island as further information comes to hand.

Light Pollution to be the focus for World Migratory Bird Day in 2022

WMBD2022

World Migratory Bird Day (WMBD) is an annual awareness-raising campaign highlighting the need for the conservation of migratory birds and their habitats.  It has a global outreach and is an effective tool to help raise global awareness of the threats faced by migratory birds, their ecological importance, and the need for international cooperation to conserve them. The day is celebrated twice a year, on the second Saturdays of May and October.  World Migratory Bird Day for 2022 will have the theme of Light Pollution.

“Artificial light is increasing globally by at least two per cent per year and it is known to adversely affect many bird species.  Light pollution is a significant threat to migratory birds, causing disorientation when they fly at night, leading to collisions with buildings, perturbing their internal clocks, or interfering with their ability to undertake long-distance migrations.

Solutions to light pollution are readily available. For instance, more and more cities in the world are taking measures to dim building lights during migration phases in spring and autumn. Best practice guidelines are also being developed under the Convention on Migratory Species to address this growing issue and ensure that action is taken globally to help birds migrate safely.”

Westland Petrels for release

Light pollution affects ACAP-listed species and other procellariiform seabirds in two main ways: during breeding on land and at sea.  On-land threats are related to breeding adults and especially fledglings becoming disoriented and falling to the ground (where they are at risk of being run over on roads or being killed by domestic or feral cats and other predators) or being killed by collisions with overhead wires when traversing from breeding site to the shore in the vicinity of well-lit areas.  Such events can happen on foggy nights and are related to phases of the moon.  ACAP-listed species known to be at risk are the Westland Petrel Procellaria westlandica, the Pink-footed Shearwater Ardenna creatopus and the Balearic Shearwater Puffinus mauretanicus.  Other procellariiform species seriously affected include Newell’s Puffinus newelli and Wedge-tailed Ardenna pacifica Shearwaters and Hawaiian Petrels Pterodroma sandwichensis on inhabited Hawaiian islands and Hutton’s Shearwater Puffinus huttoni that breeds inland on New Zealand’s South Island. Searching on these species’ names will lead to several news posts on the subject of light pollution on this website.

At-sea threats relate to bright deck lighting at night attracting mainly the smaller procellariiform birds on fishing, expedition and cruise vessels, primarily in the Southern Ocean and especially during calm, foggy conditions in the vicinity of breeding islands (click here for an example).

Featuring ACAP-listed species and their photographers: the Shy Albatross by Kris Carlyon

NOTE:  This post continues an occasional series that features photographs of the 31 ACAP-listed species, along with information from and about their photographers.  Here, Kris Carlyon, Section Head, Wildlife Health and Marine with the Department of Natural Resources and Environment Tasmania (NRE Tas), writes about the population research he has been involved with over the past 11 years on the globally Near Threatened Shy Albatross Thalassarche cauta, endemic to Tasmania, Australia.

The long-term (now in its 42nd season) monitoring programme on Shy Albatrosses was instigated by Nigel Brothers in 1980/81.  Since then, there have been numerous contributions and collaborations from a range of government and university personnel (hence the attached publication list from several researchers).

1. Albatross Island

I first visited 18-ha Albatross Island in the Bass Strait north-west of Tasmania, one of just three global breeding colonies for this species, in 2010.  This was my first field trip in my shiny new role with DPIPWE’s Marine Conservation Program (now NRE Tas) and set the tone for what has been an incredibly rewarding decade contributing to the long-term monitoring of Shy Albatrosses.  None of the three breeding islands is easy to visit.  However, access to Albatross Island in Tasmania’s north-west is relatively straightforward compared to the imposing rock pyramids of Pedra Branca and the Mewstone off the southern Tasmanian coastline, and it is here that the bulk of our monitoring efforts is undertaken.  Aerial photography provides an option for the regular monitoring of the two south coast colonies.

A 90-minute boat ride through the Hunter Island Group, followed by an intense offloading of the field team and a mountain of gear, heralds the start of one of two main monitoring trips to Albatross Island each year.  Watching the boat retreat into the agitated waters of the Bass Strait, leaving us to a week or more of living and working amongst these amazing birds, is a perpetual highlight.  A lengthy gear shuffle sees us set up camp in the huge sea cave at the north of the island, all the while welcomed by continuous chatter from the albatross colony above and barks from the island’s increasing fur seal Arctocephalus spp. residents; both species on the long road of recovery after sealers heavily exploited both the seal and albatross populations in the early 1800s.  As darkness falls and we eat dinner under torchlight, masses of Fairy Prions Pachyptila turtur return to the cave and commence their nightly and sometimes deafening chorus that continues unbroken until dawn.  I don’t sleep better anywhere else.

The rest of the trip is a happy routine of long days amongst the wind and the birds.  On a good evening, some cheap wine amongst the tussock grass, watching curious albatross or an occasional White-bellied Sea Eagle Haliaeetus leucogaster glide overhead, is a great way to recover from hours of clambering over rough ground and dodging sharp beaks.  As the sun sinks below the waves of the western Bass Strait, evenings also offer the best light for photography and the addictive but unending pursuit of trying to capture a good image of these beautiful birds.

Our long-term population monitoring, including tracking and diet studies and investigation of climate-change impacts, tells the story of gradual colony recovery.  But these birds continue to face significant threats.  Like most procellariforms, the impacts from fisheries bycatch mortality and environmental change at breeding sites and foraging areas due to a changing climate are an increasing concern for the Shy Albatross.  Our precious trips to these island outposts certainly have a sobering serious purpose and become only more important as the impacts of global heating become more apparent.  Documenting population trends is now coupled with testing of climate adaptation tools to help ensure intervention options are available if needed.

And, in the background, we continue to raise public awareness of our unique Tasmanian resident.  For this, a single photograph can prove invaluable.
