Martin Beal (BirdLife International, Cambridge, UK) and colleagues have published in the journal Biological Conservation an assessment of the key data required from GPS tracking to identify important seabird sites that could assist seabird conservation.

The paper’s abstract follows, 

“Animal tracking has afforded insights into patterns of space use in numerous species and thereby informed area-based conservation planning. A crucial consideration when estimating spatial distributions from tracking data is whether the sample of tracked animals is representative of the wider population. However, it may also be important to track animals in multiple years to capture changes in distribution in response to varying environmental conditions. Using GPS-tracking data from 23 seabird species, we assessed the importance of multi-year sampling for identifying important sites for conservation during the chick-rearing period, when seabirds are most spatially constrained. We found a high degree of spatial overlap among distributions from different years in most species. Multi-year sampling often captured a significantly higher portion of reference distributions (based on all data for a population) than sampling in a single year. However, we estimated that data from a single year would on average miss only 5 % less of the full distribution of a population compared to equal-sized samples collected across three years (min: −0.3 %, max: 17.7 %, n = 23). Our results suggest a key consideration for identifying important sites from tracking data is whether enough individuals were tracked to provide a representative estimate of the population distribution during the sampling period, rather than that tracking necessarily take place in multiple years. By providing an unprecedented multi-species perspective on annual spatial consistency, this work has relevance for the application of tracking data to informing the conservation of seabirds.”

The Rock Stars Weekend Challenge

Artists and Biologists for Nature (ABUN) has contributed to the conservation of ACAP-listed species every year since 2020 by running an annual project where contributing artists produced artworks to mark World Albatross Day on 19 June.  In the first three years some 500 artworks illustrating all 31 ACAP-listed albatrosses and petrels have been created, using photos made available by ACAP supporters to act as inspiration.  This year’s project, ABUN’s 43rd, which has been running from January to March, has been in support of the World Albatross Day theme for 2023 of “Plastic Pollution”. It has resulted in stunning artworks, which will be used by ACAP to support ‘WAD2023’ over the next three months, until the actual day on 19 June.  To get a the taste of what is to come, look at artworks ona pollution theme produced this year by just two ABUN artists, Apple Resonance and Snah.  The many others may be viewed in the growing collection in an ACAP Facebook album.

To end another successful project #43 ABUN Co-founder Kitty Harvill and Administrator Marion Schön issued a challenge.  For just one weekend this month 12 contributing artists took on the task to paint from photographs of Laysan Albatross Phoebastria immutabilis chicks losing their down prior to fledging that were taken and kindly made available by Hob Osterlund of the Kaua'i Albatross Network. Thirteen artworks were submitted, as shown above in the collage.

As Kitty Harvill writes “A big shout-out to Hob Osterlund, whose love of and dedication to Kauai’s Laysan Albtrosses shine in each of her amazing photos.”  ACAP heartily agrees with this sentiment and also thanks all the ABUN artists who contributed to the challenge: Diana L Andersen, Flávia F. Barreto, Grisselle Chock, Diane Dudzik, Lynne Waters Griffey, Kitty Harvill, Ellyn Bousman Lentz, Anne Lyon, Virginia Nicol, Alejandra Piro, Marion Schön and Shary Page Weckwerth (with two artworks).

Analysis of seabird flight tracking data reveals relationship between flight morphology and responses to varying wind speeds

Graphical Abstract Seabird morphology determines operational wind speedsGraphical abstract

Elham Nourani (Department of Biology, University of Konstanz, Germany) and colleagues have published in the journal Current Biology an analysis of wind speeds on seabird flight morphology.

The paper’s summary as follows:

Storms can cause widespread seabird stranding and wrecking, yet little is known about the maximum wind speeds that birds are able to tolerate or the conditions they avoid. We analyzed >300,000 h of tracking data from 18 seabird species, including flapping and soaring fliers, to assess how flight morphology affects wind selectivity, both at fine scales (hourly movement steps) and across the breeding season. We found no general preference or avoidance of particular wind speeds within foraging tracks. This suggests seabird flight morphology is adapted to a “wind niche,” with higher wing loading being selected in windier environments. In support of this, wing loading was positively related to the median wind speeds on the breeding grounds, as well as the maximum wind speeds in which birds flew. Yet globally, the highest wind speeds occur in the tropics (in association with tropical cyclones) where birds are morphologically adapted to low median wind speeds. Tropical species must therefore show behavioral responses to extreme winds, including long-range avoidance of wind speeds that can be twice their operable maxima. By contrast, Procellariiformes flew in almost all wind speeds they encountered at a seasonal scale. Despite this, we describe a small number of cases where albatrosses avoided strong winds at close range, including by flying into the eye of the storm. Extreme winds appear to pose context-dependent risks to seabirds, and more information is needed on the factors that determine the hierarchy of risk, given the impact of global change on storm intensity.

Hannah, who describes herself as a Native New Zealand bird artist specialising in realistic pen drawings, has written on her Facebook page the day after the event: “What a fantastic night.  ‘Welcome Home’ sold for $12,000!  I am so happy with this result and so proud of this money raised for the Antipodean Albatross”. In addition, Hannah has informed ACAP Latest News that an A1-sized and framed limited edition print of her “Subantarctic Soaring” sold for NZ$2265 at the event.

This is not the first time Hannah has raised funds for the globally Endangered and Nationally Critical Antipodean Albatross as previously reported in ACAP Latest News.  In 2022 she raised NZ$4230 partnering with Forest & Bird (BirdLife International’s National Partner in New Zealand) in its efforts towards improving fishing regulations which will make the seas safer for albatrosses and other seabirds.  On a cruise she took to New Zealand’s  sub-Antarctic Islands with Heritage Expeditions she was inspired to draw an Antipodean Albatross in “to share its beauty, but more importantly to spread awareness about their plight”.  Her donation came from the sale of prints of her artwork “Subantarctic Soaring”  (click here), as featured in the Autumn 2022 issue of Forest & Bird’s Magazine.

Heritage Expeditions contributed to the total by raising NZ$37 000 with the donation of a cabin on an expedition to New Zealand’s sub-Antarctic islands (click here).  Listen to an audio clip of Lou Sanson being interviewed on the fund raiser.
