Black-browed Albatross, winning photograph by Rodrigo Tapia Jimenez

The Photography Competition “Albatrosses, their World and Threats” organized as part of the celebrations of World Albatross Day (WAD2020) was well received, with 360 photographs from 91 photographers submitted from all over the world.

Really beautiful and stunning images were submitted.  We appreciate the participation of everyone who shared their photographs and so helped increase awareness of the threats facing albatrosses.

The jury, consisting of Christine Bogle, Pablo Cáceres, Marco Favero, Jim Hurst, Veronica López, Rodrigo Moraga, Tatiana Neves and Michelle Risi, had the difficult task of selecting 20 short-listed images which subsequently went to popular vote via WAD’s Instagram page.  Finally, of the three most highly voted photographs by the public, the jury defined 1st, 2nd and 3rd places, as given below:

1st Place:  Black-browed Albatross Thalassarche melanophris, Drake Passage by Rodrigo Tapia Jimenez @rodrigotapiawildlifephoto

Opinions of the judges:
"By far, this is the one I like most because I think represents in a very best way the life, the habitat, and freedom of the albatross.  As well a very awesome point of view and beautiful light and colours.  Also an excellent description".
"The first-place photo is what I've always wanted to see of an albatross life, what it's like to live and move through the windy oceans. This was also the most difficult shot to get”

2nd Place:  Salvin’s Albatross Thalassarche salvini, Valparaiso, Chile by Eduardo Navarro @edonavarroce

Opinions of the judges:
"Perfect moment. Beautiful bird, beautiful light, beautiful colours.  Such a nice reflection.  And a very good text as well"

3rd Place:  Salvin’s Albatross Thalassarche salvini, Quintero, Chile by Rodrigo Ortega @rodrigortega.cl

Opinion of the judges
"Special moment, good pose and capture"

Feral pigs on Auckland Island can kill White-capped Albatross Thalassarche steadi chicks, photograph by Pete McClelland

The Maukahuka Pest Free Auckland Island project has been halted by New Zealand’s Department of Conservation until further funding can be secured.  However, the project will still complete the feasibility study and draft operational plans this year for the eradication of the island’s feral pigs and cats and House Mice (click here).

The COVID-19 pandemic has largely stopped international travel round the world and New Zealand is no exception to this, with no incoming tourists.  This will affect income for the eradication project from the International Visitor Conservation and Tourism Levy.  In addition, half the project’s funding is expected to come from donors, some of whom will be struggling financially, leading to the decision by the Department of Conservation to call a pause.

This setback, not the only one, has come in the year when the inaugural World Albatross Day on 19 June had the theme “Eradicating Island Pests”.  Earlier, both the Gough Island and Midway Atoll mouse eradication projects were postponed until at least next year due to travel restrictions as a consequence of the pandemic.  On South Africa’s sub-Antarctic Marion Island all field work has been halted due to virus concerns, causing a break in decades-long monitoring of the island’s albatrosses and giant petrels.  Planning and fund-raising towards eradicating Marion’s mice over the next few years is also likely to be slowed.  Back in New Zealand field work on nominate  Antipodean Albatrosses Diomedea a. antipodensis on Antipodes Island came to a premature halt when the field team was evacuated early.

With the chance of field work and eradication projects getting going again on albatross islands next year perhaps ‘WAD2021’ needs to repeat the inaugural theme?

Cory's Shearwater in flight

Raül Ramos (Institute for Research on Biodiversity (IRBIO) Universitat de Barcelona, Barcelona, Spain) and colleagues have published in the journal Ecological Indicators on the presumed stability in trophic level over time in Cory’s Shearwaters Calonectris borealis based on feather analysis.

The paper’s abstract follows:

“Despite its importance for ecology and conservation, we are still far from understanding how environmental variability interacts with intrinsic factors and individual specialization to determine trophic strategies of long-lived taxa, mostly due to difficulties in studying the same animals over extended periods. Here, by yearly consistently sampling the first primary feather of 99 Cory’s shearwaters (Calonectris borealis) foraging in the Canary Current (CC) upwelling ecosystem, we provide robust evidence on the individual changes of isotopic ratios of carbon (δ¹³C) and nitrogen (δ¹⁵N) over 17 years. We reported a slight longitudinal decline of δ¹³C values throughout 2001–2017, even after being adjusted for the marine Suess effect (linked to the increasing CO₂ emissions). Although CC is often considered to be overexploited by industrial fisheries, we could not detect a decline in Cory’s shearwater trophic level indicating a change in the trophic web structuring, as revealed by δ¹⁵N. We found negative correlations of δ¹³C and δ¹⁵N with the CC upwelling intensity, indicating annual variability in baseline isotopic levels propagates through the food chain and it integrates in predators’ tissues. Low individual repeatabilities among years at population level indicates low long-term specialization, suggesting long-lived individuals foraging on highly productive areas can adjust their foraging strategies and diet according to environmental variability. However, individual-level repeatabilities in isotopic values showed a range of individual specialization within the population, indicating most individuals are generalist and a few of them highly specialized. First, although we found a clear influence of the upwelling intensity on the trophic ecology of birds, we could not detect any temporal trend in the trophic level of the Cory’s shearwater population, suggesting a stability in the structure of the pelagic food web of the CC over the last two decades despite the fishing pressure. Second, the existence of individual specialization highlights the importance of considering the repeated sampling of individuals to detect small changes in the trophic ecology of a population. Finally, the coexistence of individuals with different degree of specialization (from extremely flexible [generalists] to highly consistent individuals [specialists]) within a population can have deep implications on the capacity of populations to cope with environmental change.”

This book is a thorough introduction to the complex task of rehabilitating procellariiform seabirds written by world experts in the field of seabird medicine and rehabilitation.  It was written for use in Brazil and is only available in Portuguese; however, the content is universally applicable.  Rehabilitation of albatrosses, petrels and other procellariiform seabirds is a difficult task that requires exceptional skill and specialised techniques and equipment.  This publication documents the most successful techniques learned by rehabilitation centres around the world.  Veterinary care and stabilisation, correct hosing and enclosures for these birds, handling and transport, feeding, swimming and safe release are just some of the important topics covered.  This publication will go a long way towards making procellariiform rehabilitation more professional and improving the number of birds that are successfully released after rehabilitation.  I hope that the authors secure funding for English and Spanish translations in the near future.

The book’s chapter headings follow in Portuguese with English translations in parentheses:

1. INTRODUÇÃO (Introduction)
