The Eleventh Chilean Ornithological Congress (XI Congreso Chileno de Ornitología) was held last week in La Serena, Chile.  At the congress a number of papers was given on the Vulnerable Pink-footed Shearwater Puffinus creatopus (a candidate for listing within the Agreement) as well as on aspects of seabird mortality and mitigation in Chilean fisheries.

Hugh Powell has authored an article on the Near Threatened Laysan Albatross Phoebastria immutabilis in the 2014 Summer Edition of the magazine Living Bird, published by the USA's Cornell Lab of Ornithology.

The illustrated article, also available open-access online, describes the past and current conservation status of the Laysan Albatross and gives information on “How You Can Help”.  This section gives links to websites, covering such matters as recycling plastic items, asking for sustainable seafood in restaurants, visiting a breeding colony or watching albatrosses at sea, reading a children’s book on albatrosses [click here for ACAP’s list] and supporting ACAP (which is described as a “landmark effort [which] coordinates much-needed international collaborations to conserve 30 seabird species”).

The article ends:

“This is where I take inspiration from the albatross, which shows such grace in its mastery of the elements.  Each time we have attempted to address a problem, they have met us halfway.  I stood above the surf at Kilauea Point and watched albatross A081 peeling ribbons off the wind.  Its long, stiff wings curved like blades of grass, and every swoop and rise was the result of imperceptible motions of its wing tips.  This is a bird for which storms are opportunity and still air is an obstruction, I thought.  There is no serenity as absolute as an albatross facing into the wind.”

With thanks to Ed Melvin and Hugh Powell for information.

James Glass (Tristan Fisheries Department, Tristan da Cunha, South Atlantic Ocean) and Peter Ryan (FitzPatrick Institute, University of Cape Town, South Africa) published last year in the African Journal of Marine Science on seabirds coming aboard a rock lobster vessel at night in the waters of Tristan da Cunha in the South Atlantic.  Of ACAP-listed species occurring in Tristan waters only three Spectacled Petrels Procellaria conspicillata were recorded aboard and none died over a three-year period.

The paper’s abstract follows:

“The main impact of the fishery for Tristan rock lobster Jasus tristani on seabirds at the Tristan archipelago and Gough Island is through night strikes, when petrels collide with a ship after being disorientated by its lights.  Tristan fishery observers have kept records of night strikes on the MV Edinburgh since the 2010/2011 fishing season. Over the last three years, 723 seabirds from nine species were recorded coming aboard the fishing vessel, with at least 39 (5.4%) birds dying as a result. Birds killed were broad-billed prions Pachyptila vittata (41%), common diving petrels Pelecanoides urinatrix (23%), and storm petrels (Pelagodroma marina and Fregetta grallaria/tropica 36%).  All these species are listed as Least Concern globally, and the numbers killed per year are <0.1% of the island populations.  The captain and crew of the Edinburgh are aware of the problem posed by deck lights at night, and attempt to keep external lighting to a minimum.  As a result, the numbers of birds coming aboard vessels in this fishery have decreased from an average of 130 birds per night in 1989 to less than two birds per night in 2010–2013.  Currently, most incidents occur during exceptional events when circumstances require deck lights to be lit at night.  Consideration should be given to banning fishing operations at night, at least on misty nights.”

Kate Waterhouse has provided an update on the conservation status of the ACAP-listed and Vulnerable Black Petrel Procellaria parkinsoni in the latest newsletter of the Great Barrier Environmental Trust.  The species breeds only on Great and Little Barrier Islands in New Zealand’s Hauraki Gulf off North Island.  Both island populations are at risk to interactions with fisheries and only Little Barrier is free of introduced predators.

A storm on Great Barrier earlier this year caused damage to the Black Petrel’s breeding sites on the island (click here).
