Hiʻipoi with a parent

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").

“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.”

Overall Co-winner: ‘Three-metre Northern Royal Albatross Cake’ by the Royal Albatross Centre

A total of 72 entries was received for the Great Albicake Bake Off in aid of celebrating World Albatross Day last month.  Following the announcement last week of the five most-liked cakes by ACAP’s Facebook followers, here follow the five category and overall winners and runners up as decided by three independent judges.

Winner, Best Presentation theme: ‘Gough in Miniature’ by Adam Naylor

Adam Naylor writes: “Adult Tristan Albatrosses [are] 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.”

Runners Up: 2nd - Jean Purdon (Grey-headed Albatross Chick); equal 3rd - Amy King (‘Gough Island Restoration Cake’), Sheryl Hamilton & Al Wiltshire (‘Albatross Wedding Cakes from 1998’) & Michelle Risi (‘Sooty Vanillatross’).

Winner, Most Creative theme:  ‘Fruity Albatross Diomedea bananarama’ by Steffen Oppel

Steffen describes his cake: “The most sought-after albatross of any researcher who has spent a long time on remote albatross islands where there is no fresh fruit - ever.  Ingredients: banana, pear, peach, cherries, on a layer of fresh coconut sponge.”

Runners Up:  Equal 2nd - Liz Morgan (‘Grey heads amongst the Tussock’) & Nini van der Merwe (‘Gough Island Restoration Programme: Fingers Crossed for 2021!’).

Winner, Morphological Accuracy theme:  ‘Gough in Miniature’ by Adam Naylor

See description above.  Adam is a Veterinary Surgeon with the Royal Zoological Society of Scotland and is a team member of the Gough Island Restoration Programme.

Runner’s Up:  2nd - Melanie Wells (‘Light mantled Albatross’), equal 3rd - Coco & Tracey Faber (‘Sneezy and Snorky ‘), Sara Larcombe (‘Big Macca’) & Joe Naylor (aged 10, ‘Petey the Albatross’).

Winner, Eradicating Island Pests theme:  ‘Gough Island Restoration Cake’ by Amy King

Amy King (a team member this year of the Gough Island Restoration Programme) writes; “I’ve done an eradication theme cake, for Gough Island.  Hopefully having started the project this season, we get to go back out next year! Fingers crossed!  The cake has attempted to portray all three species of albatrosses breeding on the island, with a sooty chick (my favourites!), a helicopter ready to fly, and some of the mice and Sagina that are invasive.  “It was a rainbow sponge, but the colours didn’t come out so I haven’t cut it for a photo as my sister is having it tomorrow as a birthday cake!”

Runners Up:  2nd - Nini van der Merwe (“Gough Island Restoration Programme: Fingers Crossed for 2021!); 3rd - Janine Schoombie & Karen Versteegh (‘Grey-headed Albatross Ridge, Marion Island’).

Winner, Rainbow Theme:  ‘Wisdom the Albatross Cake’ by Araks Ohanyan

Araks Ohanyan’s ‘Wisdom the Albatross Cake’ wins this theme in honour of COVID-19 care givers and essential workers.  She writes: “My cake depicts Wisdom the albatross on a nest at Midway Atoll.  The cake is chocolate, and Wisdom herself is made from sculpted rice crispies and covered in fondant.  The decorations and the egg are made from fondant as well. 

I chose Wisdom as my subject because I think she's an amazing bird that has made a great contribution to the conservation of her species and brought some much-needed attention to the plight of albatrosses worldwide.”

Runners Up:  2nd - Christina Hagen (‘Laysan Rainbow Egg’); 3rd - Meagin van der Westhuizen (‘The Circle of Life Albicake’).

Adam Naylor, Overall Co-winner, with a friend on Gough Island

Overall Winners:  ‘Gough in Miniature’ by Adam Naylor and ‘Three-metre Northern Royal Albatross Cake’ by the Royal Albatross Centre

The overall winners (both depicted above) are ‘Gough in Miniature’ by Adam Naylor and the life-sized ‘Three-metre Northern Royal Albatross Cake’, sent in by Chris McCormack, Operations Manager and baked by the team at the Royal Albatross Centre at Taiaroa Head/Pukekura, New Zealand, the world’s only mainland breeding colony of Endangered Northern Royal Albatrosses Diomedea sanfordi.

Scopoli’s Shearwater at sea, photograph by 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.”
