Following on from two recent posts to ACAP Latest News of albatrosses at sea that had been daubed with paint and had a plastic band wrapped around the bill, Leandro Bugoni (Instituto de Ciências Biológicas, Universidade Federal do Rio Grande - FURG, Brazil) reports to ALN of an adult Atlantic Yellow-nosed Albatross Thalassarche chlororhynchos (globally Endangered) with a long packing strap (as commonly used to secure boxes of fish or squid bait) tightly knotted around its left leg.

The bird was spotted at sea on 22 February 2006, off southern Brazil (33.95S; 51.45W) by Captain Celso Oliveira of the long liner Ana Amaral I, which was trolling and hand lining for tuna at the time. Attention was then drawn to its ‘unusual long tail feathers’.

Leandro, aboard the long liner sampling birds for his PhD degree, then used a cast net to capture the bird, confirming that the trailing objects were not tail feathers but a white plastic packing strap.

In the hand the bird was active and appeared healthy despite a wound from the strap, suggesting it been knotted around the leg for some time. Following removal of the strap a blood sample was taken for stable isotope analysis and molecular sexing (it was determined to be a male) and moult and mensural data collected. The albatross was banded with CEMAVE/ICMBio U29584 on its right, uninjured leg and then released at sea.

It seems certain the strap had been deliberately tied to the bird’s leg, likely by a fisher for seemingly no purpose other than idle amusement.

Registration and abstract submission are now open for the 14th International Seabird Group Conference to be held in Liverpool, UK, 3-6 September 2018; until 16 March for oral and poster abstracts. Early-bird registration is available until 13 April.

“The conference promises to be an exciting showcase of the latest seabird research, located within the heart of the city of Liverpool, famous for its maritime history and cultural diversity”.

Keynote speakers include Kyle Elliott (“Keeping alight the ocean’s brightest fires of life”; McGill University, Canada), Ana Sanz-Aguillar (“Seabird survival: critical moments and mortality drivers”; Mediterranean Institute for Advanced Studies, Spain), and Thierry Boulinier (“Host-pathogen interactions in space and time: seabirds as key models to address basic and applied issues”; Le centre national de la recherche scientifique, France), whose talks about seabird ecology, physiology and conservation will complement two and a half days of oral and poster presentations.

The conference is being organized by the University of Liverpool. It will be held on the university campus within the city.

The 2018 Red List update process for birds is now under way and BirdLife International’s Red List team has begun posting new topics on the Globally Threatened Bird Forums’ website. There are fora for different categories of birds, including one for seabirds.

Two ACAP-listed albatrosses are currently under review, with information on them available on line, along with requests for comments:

Amsterdam Albatross Diomedea amsterdamensis: downlist from Critically Endangered to Endangered?

Shy Albatross Thalassarche cauta: uplist from Near Threatened to Vulnerable?

Comments on these two albatrosses will be considered in July. Preliminary proposals for changing their category of threat will then be posted. An opportunity to comment further will be given before final recommendations to IUCN are collated. The new and revised species assessments and updated factsheets will be published on the BirdLife International website and incorporated into the 2018 IUCN Red List, currently scheduled for release in November.

“This year, we are also inviting people to send in suggestions for species that may warrant an urgent Red List status change. In order to make sure that there is sufficient time for species to be given a full re-assessment against IUCN Criteria, and to be put through the forum process, the deadline for these submissions is 31 March 2018.”

Greece has expanded its network of marine protected area (MPAs) by adding 32 new sites and extending 63 others to increase protected coverage of its marine waters in the Aegean and Ionian Seas from 6% to 22%. The new sites bring the total protected area in Greek waters to over a million hectares.

“Overlap between the marine network and marine IBAs (Important Bird and Biodiversity Areas identified by BirdLife) has now jumped to 85% - thereby laying the foundation for the protection of over 60-70% of the [Greek] national seabird population, notably including the Audouin’s Gull, the Mediterranean Shag, Scopoli’s Shearwater, Yelkouan Shearwater and the European Storm Petrel.”

Scopoli’s Shearwater Calonectris diomedea (globally Least Concern) and Yelkouan Shearwater Puffinus yelkouan (globally Vulnerable) have been identified as potential candidates for ACAP listing.  Both species breed on Greek islands.
