Back in March the ACAP Information Officer met with an old sub-Antarctic island colleague, Mariëtte Wheeler, to discuss plans to get school learners involved in marking World Albatross Day in South Africa.  Mariëtte gained her PhD at sub-Antarctic Marion Island studying the effects of human disturbance on its breeding seabirds, including albatrosses, and seals.  She is now the Life Sciences Educator at Protea Heights Academy - a Maths, Science and Technology senior school within the greater Cape Town area.  The academy is one of only six nodal schools in the Western Cape to have commenced teaching marine science as a subject in 2020, initiated by and with the collaboration of Cape Town’s Two Oceans Aquarium; Mariëtte is the subject head.

Unfortunately closure of all South African schools as a consequence of the COVID-19 pandemic brought their plans to get the almost 900 learners of the school involved with ‘WAD2021’ with lectures and demonstrations in the school hall to a halt.

Mariëtte was inspired by the Great Albicake Bake Off and Colouring-in competitions held by ACAP to help raise awareness of the need for albatross conservation. Because she was still teaching her classes online throughout lockdown, she decided to make her learners more aware of the need for conserving albatrosses through a creative class competition.  Learners were asked to bake, draw, paint or make something creative “as long as there was at least one albatross included”.  The 17 participating learners used what they had available at their homes and submitted images and photographs of their creativity online.  Marienne de Villiers (CapeNature and Mariette’s PhD promoter) and Ria Olivier (Antarctic Legacy of South Africa) along with the ACAP Information Officer acted as independent judges of the creations.  The learners were also asked to vote for their favourites.  Prizes were then awarded in each category.  ACAP sponsored World Albatross Day posters for the winners and the Antarctic Legacy of South Africa sponsored a book on the natural history of Gough Island for each learner who entered and a colour A5-print of the learner’s image.  In addition, Mariëtte printed certificates of participation for each learner.

Three Laysan Albatross chicks fledge from the new colony at Kahuku Point/Kalaeokaunaʻoa on Hawaii’s island of Oahu

Laysan Albatrosses Phoebastria immutabilis are in the early stages of establishing a new breeding colony at Kahuku Point/Kalaeokaunaʻoa on the north coast of the Hawaiian island of Oʻahu.  After years of failed breeding attempts three chicks fledged from six eggs laid in the 2018/19 season, a success attributed to control of introduced mammalian predators and community outreach.  In the current 2019/20 season the breeding population increased to nine pairs, all which laid eggs.  Of these, five pairs abandoned their eggs, perhaps as a result of being disturbed.  One of these was a female-female pair which presumably laid infertile egg(s).  Of the remaining four eggs, one chick died while hatching and three hatched successfully.

The colony is looked after by the North Shore Community Land Trust with help from the U.S. Fish & Wildlife Pacific Islands Coastal Program.  The Trust has recently announced via its Facebook page that the three chicks all fledged this month. Before their departure the chicks were both metal and colour banded.  Children at the North Shore’s Hauʻula Elementary School have named the three fledglings Hiʻipoi ("to cherish and protect"), Kailani ("heavenly sea") and Pākaha ("Curious").

Collaboration for Conservation of the Yelkouan Shearwater – a webinar

LIFE Arcipelago Garnija

“A webinar on seabird conservation in the Mediterranean, with a special focus on the Vulnerable Yelkouan Shearwater Puffinus yelkouan, was held on 9 and 10 July 2020 by the LIFE Arċipelagu Garnija (LIFE14 NAT/MT/991) project.  This project closing webinar "Collaboration for the Conservation of the Yelkouan Shearwater" was organised by the project partners BirdLife Malta, Transport Malta and the Royal Society for the Protection of Birds (RSPB).  It was a key opportunity to share the results of the LIFE Arċipelagu Garnija project as well as discuss the recent conservation issues and approaches to set the way forward for international collaborations in protecting our common seabird heritage in the Mediterranean.

Due to the current COVID-19 pandemic situation, this webinar replaced the project-closing conference which was planned for the end of the project.  The two-day webinar was held on Zoom.  The webinar opened on Thursday 9 July with a keynote speech on the history of seabird conservation in Malta and challenges for seabird conservation in the Mediterranean and continued with the presentation of the project’s key results.  The presentations were followed by a session on knowledge-sharing and gap analysis for the entire Mediterranean region, identifying the actions needed to be taken to implement the international conservation action plan of the species.  On Friday 10 July, the second day of the webinar, online workshops on light pollution and current technologies to monitor seabird populations were held.”

Sex-specific foraging behaviour in Scopoli’s Shearwaters

Scopolis Searwater John Borg

Federico De Pascalisa (Dipartimento di Scienze e Politiche Ambientali, Università degli Studi di Milano, Milan, Italy) and colleagues have published in the journal Animal Behaviour on GPS-tracking of chick-rearing Scopoli’s Shearwaters Calonectris diomedea.

The paper’s abstract follows:

“Flexibility in foraging behaviour is a key individual trait, promoting adaptive responses to changing environmental conditions. Such flexibility can be especially pronounced in marine predators that forage in highly dynamic environments and pursue ephemeral and patchily distributed prey. Individual characteristics, social interactions and resource availability may all promote behavioural flexibility, which in turn may foster divergence in foraging tactics within populations. The adoption of specific foraging tactics by individuals from the same population could be driven by a complex mixture of intrinsic and extrinsic factors. We GPS-tracked chick-rearing parents of a sexually size dimorphic, avian, marine top predator, the Scopoli’s shearwater, Calonectris diomedea, across multiple foraging trips to investigate (1) intraindividual variation in foraging behaviour and (2) the effect of sex and wind conditions on the adoption of specific foraging tactics. Based on cluster analysis applied to GPS-derived behavioural patterns at the foraging trip scale, we identified variation in foraging trips, from fine- to coarse-scale foraging (FF and CF, respectively). FF trips were characterized by lower flight activity, shorter travel distances and more intensive prey-searching behaviour compared to CF trips. Individuals did not consistently perform FF or CF trips. Males were more prone to perform FF trips than females, but both sexes shifted towards CF trips with increasing wind intensity, probably to exploit the energetic advantages of dynamic soaring. We conclude that sex-specific foraging tactics reflect the interplay between sex-specific energetic optima, originating from differences in morphology and a reduction in the niche overlap between the sexes. By adopting flexible, sex-specific foraging tactics, shearwaters probably optimize their energy expenditure during the energy-demanding chick-rearing stage. Our study outlines the importance of both intrinsic and extrinsic factors in shaping interindividual variability in foraging behaviour.”
