Applications are sought for project funding that will assist the Agreement on the Conservation of Albatrosses and Petrels (ACAP) meet its objective of achieving and maintaining a favourable conservation status for albatrosses and petrels. Total funding of approximately AUD 120 000 is available for allocation.

Applications must be submitted on an ACAP Small Grants Application Form, also available from this website via the home page. When assessing project applications, preference will be given to projects that address elements of the Advisory Committee Work Programme (see Annex 4, AC10 Report) and any research priorities identified by the AC Working Groups (see AC10 Docs 11 Rev 1, 12 and 13 Rev 1). Innovative proposals making a substantive contribution to the Agreement’s objective will also be considered.

Applicants are encouraged to contact the relevant Working Group Convenors or the Advisory Committee Chair (click here to access names) to discuss the development and relevance of their application to ensure it addresses the requirements of the AC Work Programme.

Applications opened on 15 December 2017 and will close on 23 February 2018.

As agreed by AC10, applications will only be accepted from ACAP Parties. Completed applications (in any of the three Agreement languages – English, French or Spanish) are to be submitted to relevant ACAP National Contact Points, who will then forward them to the ACAP Secretariat by the 23 February deadline.

Applicants will be advised of the outcome of their applications by 15 June 2018.

It’s currently fledging time until the end of the month for ACAP-listed Westland Petrels Procellaria westlandica (globally Endangered and nationally a Naturally Uncommon Endemic) on New Zealand’s South Island from their only known breeding site at Punakaiki.

Similar to many burrowing procellariiforms that breed in the vicinity of human habitation the fledglings are at risk from becoming disoriented by night lights, resulting in groundings, collisions with power lines and vehicles (click here).

A recent posting by the Westland Petrel Conservation Trust to its Facebook Page shows the problem persists as quoted here:

“A recent night patrol of State Highway 6 adjacent to the petrel colony netted four grounded Westland Petrel fledglings at risk of being run over. Two appeared to have crashed after being disoriented by streetlights near the Punakaiki River Bridge, and the other two probably struck power lines near the Nikau Scenic Reserve a few kilometres south. Looks like they're keen to be on their way to the launching site and thrown off the cliff - this time with no glitch. Two others, also picked up near the Nikau Reserve, were not so lucky and died from their injuries.”

The four fledglings are boxed ready for release

Daniel Oro and Tim Guilford have published a letter in the journal Science arguing that more needs to be done to conserve the ACAP-listed and Critically Endangered Balearic Shearwater Puffinus mauretanicus.

The species breeds only on Spain’s Balearic Islands in the Western Mediterranean, its non-breeding distribution extends into the North Atlantic. It is at risk from fisheries bycatch, predators and disturbance at breeding sites and fall out from artificial lighting. The letter considers that the European Commission should help Spain conserve its endemic seabird.

Kalinka Rexer-Huber (Department of Zoology, Otago University, Dunedin, New Zealand) has been awarded a PhD for her study of the ACAP-listed White-chinned Petrel Procellaria aequinoctialis following field work conducted on New Zealand’s sub-Antarctic Auckland and Campbell Islands.

The thesis abstract follows:

“Albatrosses and petrels are a group of oceanic seabirds that spend most of their lives at sea. The Southern Ocean, which rings Antarctica in a continuous belt of wind and currents, supports most of the world’s albatrosses and petrels. The conservation status of many oceanic seabirds has deteriorated dramatically over the last two decades, due to mortality from incidental bycatch in fisheries and depredation by introduced mammals at breeding sites. Globally, seabird bycatch is highest in Southern Ocean waters and introduced mammals occur on a third of sub-polar and high-latitude seabird islands.

The seabird species most frequently killed in Southern Hemisphere fisheries bycatch is the white-chinned petrel Procellaria aequinoctialis. Almost three decades after substantial white-chinned petrel mortality in fisheries was first recorded, capture rates remain high despite substantial global efforts to reduce bycatch rates. Population impacts are exacerbated by introduced mammals at some breeding sites, yet some island populations are still virtually unstudied. White-chinned petrels breed on eight subantarctic island groups around the Southern Ocean. Key steps toward targeted conservation are obtaining robust estimates of abundance and at-sea distribution, and defining the scale of genetic conservation units within the species. Population-level questions in these key areas limit the ability to gauge the impact of current threats locally and around the Southern Ocean, and hinder informed conservation, management action and policy development.

This thesis broadly asks at what scale(s) processes affect species distribution, abundance and connectivity in the Southern Ocean ecosystem, with the white-chinned petrel as the focal species. It evaluates status and connectedness of white-chinned petrels breeding on subantarctic islands around the Southern Ocean via three broad approaches:

- Population size estimates for the Auckland Island and Campbell Island breeding populations, the last two island groups lacking estimates of white-chinned petrel numbers (Chapter 2);

- Tracking devices follow the at-sea movements and distribution of 150 white-chinned petrels year-round, from all major breeding islands (Chapter 3); and

- Molecular genetics tests connectedness within the white-chinned petrel metapopulation, using sequences from mitochondrial and nuclear genes as well as genomic data from every island population (Chapter 4).

This thesis provides the first robust population size estimates for white-chinned petrels at the Auckland Island and Campbell Island groups, including 11 islands (Chapter 2). Burrow numbers were sampled widely to capture spatial variability (33–241 randomised sampling sites per island). Estimated burrow numbers were corrected with detection rates and occupancy rates to estimate numbers of breeding birds. The Auckland Island group has an estimated 186,000 (95% CI: 136,000–237,000) white-chinned petrel breeding pairs, and the breeding population of the Campbell group is estimated ~ 22,000 (15,000–29,000) pairs. The New Zealand region supports almost a third of white-chinned petrels globally, substantially more than suspected. Importantly, the estimates establish repeatable population baselines. Tracking data from all major island populations except Campbell Island were analysed together, giving the first metapopulation-scale picture of the at-sea distribution of adult white-chinned petrels (Chapter 3). The movements of 150 adult petrels (9–33 petrels per island group) were tracked for an average of 369 days with light-level geolocation GLS loggers. Quantitative density estimates for white-chinned petrels show key global density hotspots (off South America, New Zealand, and southern Africa). Island population-specific distributions highlight areas used only by adults from a given island population. Island-specific distributions also show spatial segregation between island populations varying across the year to an extent unusual for seabirds, so the implications for resource partitioning are explored (Chapter 3). Using comprehensive sampling from every island population, high-resolution genomic data (60,709 genotyping-by-sequencing loci) was compared with data from widely-used mitochondrial genes (entire cytochrome b gene and the highly variable 1st domain of control region) (Chapter 4). Genomic data revealed genetic structure in white-chinned petrels at very fine scale (among islands) and at broad oceanic scales (between Atlantic and Indian Ocean regions) that was not detected in analyses of single genes. Three ocean-basin scale evolutionarily significant units, ESUs, were identified. There is promise that some island populations are sufficiently unique to link mortality in a specific fishery to a given island (Chapter 4). The results of the thesis are synthesised (Chapter 5) to explore the implications for conservation and the broader biogeographic context.”

In 2014 ACAP made a grant to New Zealand’s National Institute of Water and Atmospheric Research (NIWA) to undertake a population estimate of the Whie-chinned Petrel Procellaria aequinoctialis on Disappointment Island, Auckland Islands. The field work was carried out over the 2014/15 summer by Kalinka Rexer-Huber click here).
