Genetic study confirms two White-chinned Petrel subspecies

Kalinka Rexer-Huber (Department of Zoology, University of Otago, Dunedin, New Zealand) and colleagues have published in the journal Molecular Ecology on genetic structure of the ACAP-listed and globally Vulnerable White‐chinned Petrel Procellaria aequinoctialis.

The paper’s abstract follows:

“The Southern Ocean represents a continuous stretch of circumpolar marine habitat, but the potential physical and ecological drivers of evolutionary genetic differentiation across this vast ecosystem remain unclear. We tested for genetic structure across the full circumpolar range of the white‐chinned petrel (Procellaria aequinoctialis) to unravel the potential drivers of population differentiation and test alternative population differentiation hypotheses. Following range‐wide comprehensive sampling, we applied genomic (genotyping‐by‐sequencing or GBS; 60,709 loci) and standard mitochondrial‐marker approaches (cytochrome b and 1st domain of control region) to quantify genetic diversity within and among island populations, test for isolation by distance, and quantify the number of genetic clusters using neutral and outlier (non‐neutral) loci. Our results supported the multi‐region hypothesis, with a range of analyses showing clear three‐region genetic population structure, split by ocean basin, within two evolutionary units. The most significant differentiation between these regions confirmed previous work distinguishing New Zealand and nominate subspecies. Although there was little evidence of structure within the island groups of the Indian or Atlantic oceans, a small set of highly‐discriminatory outlier loci could assign petrels to ocean basin and potentially to island group, though the latter needs further verification. Genomic data hold the key to revealing substantial regional genetic structure within wide‐ranging circumpolar species previously assumed to be panmictic.”Kalinka Rexer-Huber holds a White-chinned Petrel on New Zealand's Adams Island in the Auckland Island Group, photograph by Graham Parker

“Albatrosses are magnificent and unique birds”. The Convention on Migratory Species’ Acting Executive Secretary, Amy Fraenkel supports Word Albatross Day

In May this year Ms Amy Fraenkel took over the reins as Acting Executive Secretary of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), following the untimely passing of the previous Executive Secretary in January.   It was discussions held at Conferences of the Parties to the Convention on Migratory Species in the 1990s that led the way for the signing of the Albatross and Petrel Agreement (ACAP) in June 2001.  ACAP is one of seven “daughter” Agreements of the CMS Family.  

Fitting then that Ms Fraenkel has written to ACAP Latest News in support of the inauguration of a World Albatross Day on 19 June next year, noting that albatrosses are “flagship species” offered protection under the CMS (where they are all listed on its Appendices).  The Acting Executive Secretary’s statement follows:

“Albatrosses are magnificent and unique birds, and are flagship species protected under the Convention on Migratory Species.  World Albatross Day provides an excellent opportunity to raise awareness of these beautiful birds and the threats that they face – including being caught in fishing operations, plastic pollution, climate change and invasive predator species.”

In response, ACAP's Executive Secretary, Christine Bogle and the Chair of its Advisory Committee, Nathan Walker have expressed their appreciation of the CMS Acting Executive Secretary’s support towards the Agreement's efforts to inaugurate World Albatross Day next June.

Moving out of harm’s way: an Antipodean Albatross chick gets a helping hand during the “Million Dollar Mouse” eradication project

One member of the “Million Dollar Mouse” field team on New Zealand’s Antipodes Island aimed at eradicating House Mice Mus musculus in 2016 was Keith Springer, with the dual roles of Operational Advisor and Safety Officer.  Keith had previously managed a similar successful eradication exercise on Australia’s Macquarie Island so was well fitted for these roles.

Keith writes to ACAP Latest News with a special memory of his time on the island:

“We were about to change the orientation of the flight line for baiting the Antipodes, due to a wind change, and this chick [of a globally Endangered Antipodean Albatross Diomedea antipodensis] on its nest would have been nearly under the helicopter as it hovered to pick up a load of bait.  So we moved the chick and put it into an empty bait pod strewn with tussock - out of the wind and the noise and the proximate human activity.  When we opened the pod at the end of the day to return it to its nest it was fast asleep.”

More information on the incident comes from the Department of Conservation’s Project Report written after completion of the eradication attempt as precised here: “Bait pods were positioned  … to avoid as far as practicable, impacts on Antipodean Albatross chicks on nests at the time.  Seven albatross chicks were on nests within 50 m of active areas at the bait-loading site, exposed to the greatest amount of low-altitude helicopter activity.  When exposed [to strong rotor wash], chicks stayed sitting on the nest, tucking their head down or under their wing without obvious alarm.  In most cases the response was like that observed during frequent stormy conditions.  On two occasions an albatross chick was uplifted from its nest during loading as the wind direction and limited number of remaining bait pods meant the position of helicopter would have directed severe rotor wash towards it.  The chick was placed in an empty wooden pod lined with tussock and enclosed for up to three hours.  It was asleep when retrieved from the pod on the first occasion and again seemed settled on the second occasion.  It [was] transferred back to its nest each time without any issues and fledged in February 2017.”

All seven chicks within the load site were alive at the completion of operations and six of the seven (86%) fledged successfully in early 2017.  Outside the load site the fledging rate of chicks alive at the time of bait sowing was 90%; this difference is not statistically significant.

Let’s hope the chick survives it juvenile years at sea and in a few years returns to Antipodes to commence breeding on a now mouse-free island, to be identified by the band placed on it as a chick.

Next year the inaugural World Albatross Day on 19 June will have the theme “Eradicating Island Pests”.  The success on Antipodes in eradicating House Mice points the way to more eradication efforts that World Albatross Day will attempt to highlight and celebrate.

Short-tailed Albatrosses not doing badly among decreases in breeding seabirds in Japan

Masayuki Senzaki (Center for Environmental Biology and Ecosystem Studies, Tsukuba City, Japan) and colleagues have published in the journal Bird Conservation International on population changes in breeding seabirds in Japan, including of ACAP-listed albatrosses.

The paper’s summary follows:

“Global seabird populations are in decline, with nearly half of all seabird species currently in an extinction crisis.  Understanding long-term seabird population trends is an essential first step to inform conservation actions.  In this study, we assembled historical breeding records of seabirds throughout the Japanese archipelago and quantified the long-term population trends of 10 major breeding seabird species using a hierarchical Bayesian state-space model.  The model revealed that six species had increasing or no detectable trends (Short-tailed Albatross Phoebastria albatrus, Leach’s Storm Petrel Oceanodroma leucorhoa, Pelagic Cormorant Phalacrocorax pelagicus, Japanese Cormorant Phalacrocorax capillatus, Spectacled Guillemot Cepphus carbo, and Rhinoceros Auklet Cerorhinca monocerata).  However, decreasing trends were found not only in nationally threatened species (Common Murre Uria aalge, and Tufted Puffin Fratercula cirrhata) but also common species that are often described as abundant (Black-tailed Gull Larus crassirostris and Slaty-backed Gull Larus schistisagus).  These declining species have declined to 3–35% of baseline levels over the past 30 years.  This study provides the first evidence of long-term declines in common and widespread seabirds in Japan.”

In the service of conservation: support for World Albatross Day comes from five wildlife artists

Five artists who have depicted albatrosses in their outputs come together to support next year’s inaugural World Albatross Day on 19 June.  Examples of their works and their statements in support of World Albatross Day follow.

Kitty Harvill

 

“I fell in love with Wisdom, the 68-year old Midway Laysan Albatross, while creating illustrations for the book by the same name.  She’s well named, and has much to teach us as conservationists and activists battling for the survival of our planet - patience, perseverance and setting an example by making waves that will carry forward, further than we might ever have dreamed.” - Kitty Harvill, Brazil, Signature Member, Artists for Conservation; Co-founder, ABUN - Artists & Biologists Unite for Nature; illustrator, Wisdom: the Midway Albatross: Surviving the Japanese Tsunami and other Disasters for over 60 Years.

Caren Loebel-Fried

 

“The albatross has long been my muse.  Traveller of vast distances on long, thin, glider wings, passionate dancer, exuberant vocalizer, so committed to a mate and a youngster.  I’ve been lucky to know albatrosses, but their lives are mostly hidden from us humans.  Our lack of awareness makes them even more vulnerable than they already are.  World Albatross Day, a yearly celebration of these incredible creatures, brings the albatross into our lives, and knowledge can spark the desire to protect our natural world.” - Caren Loebel-Fried, Hawaii, USA, artist, naturalist, and author of children's books, including A Perfect Day for an Albatross.

 

 

 

 

 

 

Gavin Mouldey

"Although albatross don’t frequent the coast where I live and work, seabirds and the sounds of waves are ever present.  Toroa in Māori means ‘albatross’, and is also the given name of the 500th chick hatched at the Taiaroa Head Royal Albatross Colony. The six months spent researching, drawing and painting the book Toroa’s Journey left me in awe of this amazingly resilient individual and his species’ ability to overcome natural challenges. There were also many moments of sadness and frustration over the less natural challenges they face." - Gavin Mouldey, Kapiti Coast, New Zealand, illustrator, Toroa's Journey.

 

Jamie Watts

 

 

“Albatrosses remain under serious threat, although heroic efforts from a few have slowed the impact of fisheries on some populations.  World Albatross Day aims to celebrate the exquisite beauty of these animals, and remind us to work harder to bring them back from the brink.” - Jamie Watts, UK, illustrator, lecturer and expedition guide.

Leigh Wolfaardt

 

 

 

 

 

 

 

“Albatrosses are truly magnificent creatures, an absolute wonder and delight to observe in flight, gliding effortlessly above the waves.  They are a never-ending source of inspiration for my art.  World Albatross Day provides an important opportunity to promote awareness of these wonderful, but highly threatened, denizens of the oceans and skies.” – Leigh Wolfaardt, South Africa, artist and illustrator.
