A pair of Vulnerable Short-tailed Albatrosses Phoebastria albatrus are currently aiming to hatch their third egg on Eastern Island, part of the USA’s Midway Atoll.

Carl Safina, celebrated award-winning author of “Song for the Blue Ocean” (1997), “Eye of the Albatross” (2002) and “The View from Lazy Point” (2011) will give a seminar entitled Eye of the Albatross at the University Hawai'i at Manoa on Oahu, Hawaii on 17 January (click here).

Carl is President of the Blue Ocean Institute which he founded in 2003.

From the lecture’s flyer:

“These immense creatures we call “albatross” are the greatest long-distance wanderers on Earth.  Dr. Carl Safina, President of the Blue Ocean Institute, followed albatrosses to the far corners of the world, including Midway Atoll, in the course of researching his book, Eye of the Albatross.  He shares what their survival teaches us about persistence, hope, and how the oceans are changing.”

In Chile’s western Patagonia huge numbers of fjords and archipelagos make up one of the least populated and explored areas in the World.  Among this complex system lie islands such as Isla Diego de Almagro that are exposed to the severe weather conditions of the Cape Horn current and western drift winds.  The western coastline of the 525-ha island is composed of high cliffs and offshore islets.  Isla Diego de Almagro has been a Chilean National Reserve ("Reserva Nacional Alacalufes") since 1969 and has been identified as an Important Bird Area (IBA) by BirdLife International.

The western coastline of Isla Diego de Almagro

Diego de Almagro was first reported as supporting breeding Near Threatened Black-browed Albatrosses Thalassarche melanophris in January 1984 with abundance estimates of around 15 000 breeding pairs made by the late Gerry Clark’s Totorore Expedition.  This estimate was later confirmed by a count of 15 594 breeding pairs in six colonies scattered along offshore islets and the exposed western-facing cliffs from photographs taken from the yacht Tooluka in September 2001.

An estimated total of 122 920 pairs of Black-browed Albatrosses breed within Chile at six island localities.  Following Islas Diego Ramírez and Ildefonso, Isla Diego de Almagro supports the third largest population in Chile.

The prevailing weather conditions in the region and rugged terrain on Diego de Almagro make it difficult both to undertake aerial photographic surveys and-based monitoring with walking trips of up to 8-10 hours being necessary to visit even the most accessible breeding colonies.

Breeding Black-browed Albatrosses on Diego de Almagro

Trackers deployed on 13 Black-browed Albatrosses on Diego de Almagro during incubation in 2001 confirmed the species’ occurrence along the Chilean continental shelf, overlapping with commercial fisheries in the region.

Diego de Almagro's shoreline contains much washed-up debris from fisheries (e.g. nets, buoys), and plastic artefacts such as lighters, lubricant bottles and bags; the last widely distributed across the island by the dominant windy conditions.  In contrast with more southerly colonies (Isla Diego Ramírez >700 km southward), Diego de Almagro shows signs of invasive rodent presence with House Mouse Mus musculus faeces observed around albatross nests.  In addition, the introduction of alien predators such as domestic dogs and cats via landings made by artisanal fishers on Diego de Almagro remains an ongoing risk (click here).
