The Albatross and Petrel Agreement (ACAP) took the lead with the inauguration of World Albatross Day this year.  As well as contacting environmental NGOs and other organisations in many countries to ‘spread the word’ and encourage their participation, the Agreement ran four competitions to raise awareness among the public of the threats faced by albatrosses.

Results of three of these competitions (the Banner Challenge, a Colouring-in Competition and a Photography Competition) have now been announced on these pages.  It is now time to announce the results of the fourth competition, the Great Albicake Bake Off.

A total of 72 entries was received by the deadline, each made up of one or more images of the cake and a short description.  A single image of each cake was posted to an album on ACAP’s Facebook page and followers of the page were invited to vote for their favourite cake (or cakes) by liking images.  A reasonable period of time was given to allow for the voting and the results are now in and the five most popular cakes are shown here, along with their descriptions.

The winning cake entitled “Grey-headed Albatross Ridge, Marion Island” with 216 ‘likes’ is by Janine Schoombie, a former Marion field scientist, and her mother, Karen Versteegh.  Janine describes their cake: “Our cake is inspired by the inland ridge on Marion Island where a large portion of the Grey-headed Albatrosses breed, aptly named Grey-headed Albatross Ridge.  Visible from the nearest field hut is a Grey-headed Albatross long-term monitoring colony and a waterfall with a few breeding Sooty Albatrosses.  Both these species are currently listed as Endangered on the IUCN Red List.  We tried to capture the beautiful features of the birds as well as the terraced breeding colonies characteristic of the Ridge, complete with lush tussock grass overhanging the grey lava rock faces.  It was also important for us to add the presence of mice around the colony of albatrosses to represent the current threat these birds are facing.

The bottom tier is a dark chocolate cake with two gluten-free banana cakes as the middle and top layers. The cake is covered with a smooth cream cheese icing for the grey lava and green tussock grass.  The albatrosses and mice are made from home-made marshmallow fondant and sit atop cake cut-out nests covered with chocolate buttercream icing and green coloured coconut to represent peat used in building nests.  The waterfall is made from coloured white chocolate ganache.”

Emily Mowat Wanderer egg cake

 “Wandering Albatross Chick-hatching Cake” by Emily Mowat

Coming in second with 105 likes is “Wandering Albatross Chick-hatching Cake” by Emily Mowat, a former Macquarie Island albatross researcher.  She writes “The creation is a Wandering Albatross chick hatching on its nest.  The cake is all vegan chocolate cake with chocolate and peanut butter ‘nesting material’ and a white chocolate egg with a marzipan bill.”

Adam Naylor 2 

Third placed is by Adam Naylor, with 101 likes.  Called “Gough in Miniature”, Adam describes it as "adult Tristan Albatrosses displaying on the summit of a chocolate sponge Gough Island.  On the cliffs below invasive mice and Sagina plants run rampant, showing the threats to this incredible place and the importance of restarting the Gough Island Restoration Programme”.

Jean Purdon 3

The fourth cake by 99 Facebook likes was submitted by Jean Purdon, another ex-Marion Island researcher.  She writes “Here is a Grey-headed Albatross chick on Marion Island made out of vanilla cake with colour sprinkles inside.  It is covered in fondant and the Albi is covered in candy floss.  I modelled the cake on the attached photo [above] that I took after spending a year on the island working on the Marion Island Marine Mammal Programme.  I added the Mus musculus to highlight the plight of Albi chicks on mouse-infested sub-Antarctic islands.”

Melanie Wells Light mantled Albatross 4

Rounding off the top five with 81 likes is the entry by Melanie Wells (another ex-Macquarie Island researcher).  She describes her creation as “a Light mantled Albatross.  The cake is basic chocolate with buttercream frosting (using activated charcoal for colouring) and marzipan to make feet, bill & eye - all vegan.  The cake is inspired by my time working on Macquarie Island where 10% of the global population of this species breeds.  Mark-recapture monitoring, primarily from chick banding, has been conducted on Macquarie Island since 1955.  This highly charismatic species (seems to be everyone's fave alby who has had the pleasure of meeting one) is particularly memorable for its haunting "PEEE-AWWW" call (which the bird is doing in the image) ".

Another casualty of COVID-19: New Zealand’s Auckland Island pest eradication project gets put on hold

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?

Lack of temporal trend over 17 years in the trophic level of Cory’s Shearwaters suggests a stable food web

Corys Shearwater in flight 

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.”

Book review. Rehabilitation of procellariiform seabirds in Brazil, a manual in Portuguese


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)

2. BIOLOGIA GERAL E ESPÉCIES COM OCORRÊNCIA NO BRASIL (General biology and species occurring in Brazil)
