The Albatross Task Force’s latest annual report describes mitigation progress in Argentina, Chile, Namibia and Peru

Oli Yates, BirdLife International‘s Albatross Task Force Programme Manager writes to ACAP Latest News with news of the task force:

“It has been a busy year for the Albatross Task Force (ATF), and our teams have made good progress in achieving their objectives towards reducing the bycatch of vulnerable seabirds in some of the world’s most deadly fisheries.  The annual progress report just released gives a full update country by country, but I would like to highlight a few of the major successes of the year.

I’m happy to say that 8/10 of our high-priority fisheries now have regulations to protect seabirds, following an announcement from Argentina that seabird regulations are to be introduced by May 2018 that will require trawlers to use bird-scaring lines. The benefit for seabirds in Argentina will be huge, as the main trawl fleet is responsible for the death of 13 500 Black-browed Albatrosses Thalassarche melanophris a year, an impact we expect to reduce by over 85% based on experimental results.

Across the Atlantic in Namibia, since regulations came into force there, 100% of trawl and demersal longline vessels have now been provisioned with bird-scaring lines, constructed through our collaboration with a local women’s group [Meme Itumbapo]. By next year we hope to show that Namibia has achieved significant bycatch reductions as we have previously documented in South Africa. This will be a major win, as our estimates for the two Namibian fleets suggest in excess of 25 000 seabirds were previously killed annually. 

Our work in small-scale fisheries has also leapt forward over the last 12 months; in Chile we have shown that modifications to purse-seine net design has the potential to reduce shearwater bycatch massively, and in Peru trials of net lights have virtually eliminated bycatch of not only seabirds, but also turtles and marine mammals. This is all hugely exciting as no mitigation measures previously existed for these types of fisheries.

All of these successes have only been possible due to the collaborative efforts between our in-country partners, the Royal Society for the Preservation of Birds and BirdLife International, plus generous funding from RSPB membership, external sponsors and many kind individual donations. We are extremely thankful for the continued support we receive, without which we would not be able to keep up the fight to save the albatross.”

ACAP attends the 21st Session of the Indian Ocean Tuna Commission in Indonesia

The 21st Session of the Indian Ocean Tuna Commission (IOTC) was held in Yogyakarta, Indonesia, from 22-26 May. The Albatross and Petrel Agreement was represented by Anton Wolfaardt, Convenor of its Seabird Bycatch Working Group.

Previously, the IOTC’s Working Party on Ecosystems and Bycatch (WPEB) recommended at its 12th Meeting held in September 2016 that when the IOTC Seabird Conservation and Management Measure (Resolution 12/06 On Reducing the Incidental Bycatch of Seabirds in Longline Fisheries of 2006) is next reviewed, the line-weighting specifications be updated to conform with the latest ACAP advice.

It further recommended that the two hook-shielding devices recommended by ACAP as best-practice measures be incorporated into a revised IOTC Seabird Conservation and Management Measure as additional mitigation options for use in IOTC fisheries operating south of 25°S (the area of application of Resolution 12/06).  These recommendations were subsequently endorsed at the 19th Session of the IOTC’s Scientific Committee in December 2016.

On the basis of IOTC’s scientific support for ACAP’s best-practice advice, some IOTC Contracting Parties were considering drafting a proposal to update Resolution 12/06 to bring it closer to the current ACAP advice. Later in the year, Parties decided they needed more time to discuss the proposal further with their relevant country agencies, and intend to continue working towards a proposal in 2017, for submission to the 2018 IOTC Commission meeting.

ACAP will continue to work with its Parties, IOTC Contracting Parties, and other RFMOs, to help support the adoption and implementation of seabird bycatch mitigation measures that are informed by ACAP’s best-practice advice.

Makers of bird-scaring lines get to see the albatrosses they work to save

For five years or so members of the Ocean View Association for Persons with Disabilities (OVAPD) in the southern part of the Cape Peninsula have been making bird-scaring lines for South African long liners and trawlers (click here).

This year a number of association members got to see albatrosses and other seabirds at sea for the first time on an ocean-going cruise south of Cape Town organized by BirdLife South Africa as part of its 2017 AGM “Flock at Sea”.  BirdLife South Africa reports:

“When the members of the Ocean View Association for Persons with Disabilities (OVAPD) boarded the MSC Sinfonia, the joy and excitement on their faces was heart-warming. Until now the closest they had got to an albatross was the stuffed Wandering Albatross that the Albatross Task Force keeps for educational purposes. Not only was this the first time that many of them would be going out into the open ocean, but it was their first opportunity to see the birds that their bird-scaring lines are instrumental in protecting.

'A Sooty Albatross to the right!' the seabird guide shouted. There it was, the first albatross sighting for the team. Describing the experience, Ronald Stevens [of OVAPD] said, 'To see a live albatross is the most amazing thing, and for us to know that we help save them is wonderful.'

The proudest moment for the OVAPD team came when they were invited onto the stage at the start of the Albatross Task Force lecture describing the success that bird-scaring lines have had in reducing seabird bycatch. This was the formal recognition of their important contribution to seabird conservation.”

Farther north in southern Africa bird-scaring lines for use on fishing vessels in Namibia are manufactured by the Meme Itumbapo Women’s Group, made up of hitherto unemployed women working from their headquarters “Bird’s Paradise,” in Walvis Bay (click here and here).

A plastic spoon and a balloon are successfully removed from a Southern Giant Petrel

Wildbase Hospital, attached to Massey University, is New Zealand's only dedicated wildlife hospital, treating numbers of birds, including those listed as globally threatened.

Recently (11 June), the hospital received an ACAP-listed Southern Giant Petrel Macronectes giganteus, thought to be a juvenile by its uniform brown plumage, that had been found in a distressed state “floundering in the sea” by surfers at Castlecliff, on the west coast of New Zealand’s North Island.  Wildbase Co-director Brett Gartrell said an initial X-ray showed nothing wrong. A flexible fibre-optic gastroscope was then fed into the bird’s stomach under general anaesthesia then found that plastic items were causing the distress (click here).

The plastic items the petrel had swallowed are displayed

“X-rays, which are taken from every bird who enters the hospital, cannot detect latex or plastic in the animal's stomach and is often only found during a post mortem examination.  The plastic can sit in an animal’s stomach preventing other food from being digested, can cause irritation to the stomach’s lining, gastric ulcers, or in rare cases can move into the intestines and cause more serious obstructions.  [It] can cause ulcers of the gut and erode the stomach."

The plastic items were removed from the bird's stomach (see the video) and the bird is now recovering at Wildbase.  “We pulled out a whole spoon, pink balloon and some sharp unidentifiable plastic.  The team was very excited to remove the contents from the stomach, but the sad thing is that many animals who swallow plastic will die before they make it to us.”

Short-tailed Shearwaters fly to Bouvetøya, 2000 km west of their known range in the Southern Ocean

Peter Ryan (FitzPatrick Institute, University of Cape Town, South Africa) and colleagues have published in the journal Polar Biology on the distribution of the Short-tailed Shearwater Ardenna tenuirostris in the Southern Ocean.

The paper’s abstract follows:

“Short-tailed Shearwaters Ardenna tenuirostris are transequatorial migrants that breed at islands in southern Australia and spend the austral winter in the North Pacific. Adults feeding chicks undertake long foraging trips into Antarctic waters (to 70°S) across a broad longitudinal range (mainly 55–180°E). In mid-March 2017, we observed thousands of shearwaters in the vicinity of Bouvetøya (from 55°S 0°E to 50°S 8°E). These observations occurred more than 2000 km west of the documented range of this species, and raise the possibility that some Short-tailed Shearwaters migrate to the North Atlantic Ocean. Further observations are needed to determine whether this is a regular behaviour that has been overlooked in the past due to confusion with Sooty Shearwaters A. grisea, or whether 2017 was an unusual year for Short-tailed Shearwaters.”
