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.”

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.

Thirty-six eggs. New Zealand’s mainland Northern Royal Albatrosses start a new breeding season

 Buttons NRA Taiaroa‘Buttons’ (see text) in incubating position

A total of 36 eggs was laid in November to commence the 2021/22 breeding season for New Zealand’s only mainland population of globally Endangered and nationally Naturally Uncommon Northern Royal Albatrosses Diomedea sanfordi on the end of the Otago Peninsula at Pukekura/Taiaroa Head.

Candling of eggs in the closely managed colony has revealed that 33 of the 36 eggs remain viable.  One egg was broken, with its parents then having left the headland for the season.  One pair laid an infertile egg, and one had an early dead embryo. One of the fertile eggs belongs to the male ‘Buttons', colour banded BOR (blue orange red).  “Buttons will be turning 33 early next year - let’s see if he lives as long as his amazing mum Grandma!”  Grandma reached a banded age of 51.5 years and an actual age of at least 60 years, regularly raising chicks until the year she disappeared (click here).

The breeding birds also include OGK and YRK (Orange, Green, Black and Yellow, Red, Black) who are the live-streaming Royal Cam pair for 2021/22, as they were two years’ previously when they fledged a chick named Atawhai (click here).  Successfully breeding Northern Royal Albatrosses take a year off and so only breed every second year.  In addition to the live-streaming service, the Royal Cam pair is on view to the COVID-19-vaccinated public from the Richdale Observatory; its fertile egg was laid on 9 November 2021.

The globally Vulnerable Short-tailed Albatross Phoebastria albatrus pair is back for another breeding season on the USA's Midway Atoll – the sole pair that currently breeds on the North Western Hawaiian island.  Known as George and Geraldine, George was first seen back on Midway’s Sand Island on 20 October this year.  Several days later, Geraldine was photographed together with George.  On 26 October the male was found sitting on their new egg close to last season’s nest site.

They commenced breeding on the island in 2018 after first meeting up on the island in 2016 and have attempted breeding every year since.  So far, they have successfully fledged three chicks.  Read more about their years together here.
