Radar shows Hawaiian Petrels and Newell's Shearwaters on the island of Kaua‘i are on the way down

André Raine (Kaua‘i Endangered Seabird Recovery Project, Hanapēpē, Kaua‘i, Hawaii, USA) and colleagues have published in the journal The Condor: Ornithological Applications on population changes in globally Vulnerable Hawaiian Petrels Pterodroma sandwichensis and globally Endangered Newell's Shearwaters Puffinus newelli on the Hawaiian island of Kauai.

The paper’s abstract follows:

“The island of Kaua‘i, Hawaii, USA, holds a large breeding populations of the endangered Hawaiian Petrel (Pterodroma sandwichensis) and a majority of the world population of the threatened Newell's Shearwater (Puffinus newelli). We evaluated island-wide population trends of both species. For Newell's Shearwaters, we considered radar counts at 13 sites between 1993 and 2013 and annual island-wide tallies of fledglings retrieved after being grounded by light attraction in 1979–2015 (Save Our Shearwaters [SOS] program). For Hawaiian Petrels, we considered radar counts alone. Radar data indicated a 78% decline overall in numbers of Hawaiian Petrels (at an average rate of ∼6% per year) and a 94% decline overall in numbers of Newell's Shearwaters (at an average rate of ∼13% per year) during the survey period. Most (92%) radar sites showed significant declines of Newell's Shearwaters across the entire survey period, as did 62% of sites for Hawaiian Petrels. The SOS recovery effort collected 30,522 Newell's Shearwater fledglings between 1979 and 2015. When we compared this dataset in pre- and post-Hurricane Iniki (September 1992) periods, we found a significant downward trend after Hurricane Iniki, similar to the trend seen in the radar data. The large-scale declines found in this study are not surprising, considering the significant threats facing both species on Kaua‘i, which include powerline collisions, light attraction, introduced predators, and habitat modification—threats which were potentially exacerbated after Hurricane Iniki. Improved conservation initiatives and an increased understanding of the various threats facing the 2 species are key to reversing these declines.”

Read all about it! Documents for ACAP’s meetings in New Zealand next month are now on line

ACAP will hold the 10th Meeting of its Advisory Committee in Wellington, New Zealand next month, preceded by meetings of its Seabird Bycatch Working Group (SBWG8) and Population and Conservation Status Working Group (PaCSWG4).

Meeting Documents (available in the three ACAP languages of English, French and Spanish) and Information Papers (available in their submitted language only) are now publicly available on this website. To access them click on documents on the home page bar and then open Advisory Committee and Working Groups. Most documents may be read in their entirety but some have been password-restricted by their submitting Parties and only their abstracts are in the public domain.

Want to know what the 13 ACAP Parties have been up to of late in conserving albatrosses and petrels? Then consult their 2017 Implementation Reports to the advisory committee here.

Provisional agendas and meeting schedules are also available for consultation on this web site at the above links.

Several social events are planned for the ACAP meetings next month in Wellington, New Zealand

Next month the 10th Meeting of ACAP’s Advisory Committee will be hosted by New Zealand in the capital city of Wellington. The meeting will be preceded by meetings of two of its three working groups. A number of social events have been planned for the two weeks of meetings as set out in the meetings’ third circular and summarised below.

AC10 will kick off with New Zealand hosting an evening welcome event on Monday 11 September in the Museum of New Zealand Te Papa Tongarewa. This event will include the Seabird Smart Award for 2017 presentation by Southern Seabirds Solutions.

The next evening the Royal Forest & Bird Protection Society of New Zealand (a BirdLife national partner) has invited delegates and attendees to drinks and a light meal to celebrate New Zealand’s role as seabird capital of the world. The reception will be held in Forest & Bird’s national office in Wellington.

New Zealand will also be hosting a field trip to Zealandia - “the world’s first fully-fenced urban ecosanctuary” - for all AC10 delegates on Thursday 14 September. Visits to the collections at the Te Papa will also be arranged. A six-hour pelagic trip to the Cook Strait, separating New Zealand’s North and South Islands, has been scheduled for up to 20 delegates on Sunday 10 September. This trip will be weather dependent and ACAP’s Information Officer hopes the sea will be forgiving enough for him to enjoy fully the planned on-board barbecue lunch.

In addition, ACAP will hold a Pterodroma Workshop on Saturday 9 September. Persons wishing to attend the workshop should register by 25 August.  For the workshop agenda and the registration form click here.

A discussion on the plight of the globally Vulnerable Antipodean Albatross Diomedea antipodensis, endemic to New Zealand, will be conducted in the meetings’ margins as time permits.

Combating avian pox: insecticide spraying improves breeding success of Shy Albatrosses

Rachael Alderman (Department of Primary Industries, Parks, Water and Environment, Hobart, Tasmania, Australia) and Alistair Hobday have published in the journal Deep Sea Research Part II: Topical Studies in Oceanography on using an insecticide to combat avian pox in the Shy Albatross Thalassarche cauta. Survival of sprayed chicks was significantly higher than of those in control areas.

The paper’s abstract follows:

“Conservation of marine species typically focuses on monitoring and mitigating demonstrated stressors where possible. Evidence is accumulating that some species will be negatively affected in the future by climate change and that reduction of existing stressors may not be sufficient to offset these impacts. Recent work suggests the shy albatross (Thalassarche cauta) will be adversely affected by projected changes in environmental conditions under plausible climate change scenarios. Furthermore, modelling shows that elimination of the principal present-day threat to albatrosses, fisheries bycatch, an achievable and critical priority, may not be sufficient to reverse projected population declines due to climate impacts, which cannot be directly eliminated. Here, a case study is presented in which a range of intervention options, in preparation for predicted climate change impacts, are identified and evaluated. A suite of 24 plausible climate adaptation options is first assessed using a semi-quantitative cost–benefit–risk tool, leading to a relative ranking of actions. Of these options, increasing chick survival via reduction of disease prevalence through control of vectors, was selected for field trials. Avian insecticide was applied to chicks’ mid-way through their development and the effect on subsequent survival was evaluated. Survival of treated chicks after six weeks was significantly higher (92.7%) than those in control areas (82.1%). This approach shows that options to enhance albatross populations exist and we argue that testing interventions prior to serious impacts can formalise institutional processes and allow refinement of actions that offer some chance of mitigating the impacts of climate change on iconic marine species.”

"Just like a red balloon": surgery removes ingested plastic from a translocated Laysan Albatross chick

Lindsay Young of Pacific Rim Conservation has reported on a successful operation to remove a piece of ingested plastic and pieces of a red balloon from a Laysan Albatross Phoebastria immutabilis chick.  The bird was being hand-reared at the James Campbell National Wildlife Reserve on the Hawaiian island of Oahu as part of an attempt to create a new colony not subject to predicted sea-level rise.

The translocated chick, which was underweight when collected was failing to thrive and gain mass, but after removal of the foreign items went on to fledge successfully (although still underweight); read her illustrated account here.  A video clip taken during an endoscopy that followed an ultrasound scan of the albatross reveals the offending items.

Meanwhile, over in Australia, a balloon and a plastic spoon have been removed from the stomach of a Southern Giant Petrel Macronectes giganteus in a similar operation (click here).  In both cases the ballons were coloured red, suggesting a preference for items of that colour -as has been suggested for North Pacific albatrosses swallowing cigarette lighters.  Seems the lyrics of the "Red Balloon" song by Charli XCX need a rewrite:

"If you got troubles, let 'em go
Let 'em soar so high, high into the sky
Just like a red balloon

Ah ooh!
Don't let your worries get to you
Let 'em float on by, high into the sky
Just like a red balloon"
