Msrtyna Syposz (Department of Zoology, University of Oxford, UK) and colleagues have published in the open-access journal Scientific Reports on laspects of ight pollution affecting Manx Shearwaters Puffinus puffinus.

The paper's abstract follows:

“There is increasing evidence for impacts of light pollution on the physiology and behaviour of wild animals. Nocturnally active Procellariiform seabirds are often found grounded in areas polluted by light and struggle to take to the air again without human intervention. Hence, understanding their responses to different wavelengths and intensities of light is urgently needed to inform mitigation measures. Here, we demonstrate how different light characteristics can affect the nocturnal flight of Manx shearwaters Puffinus puffinus by experimentally introducing lights at a colony subject to low levels of light pollution due to passing ships and coastal developments. The density of birds in flight above the colony was measured using a thermal imaging camera. We compared number of flying shearwaters under dark conditions and in response to an artificially introduced light, and observed fewer birds in flight during ‘light-on’ periods, suggesting that adult shearwaters were repelled by the light. This effect was stronger with higher light intensity, increasing duration of ‘light-on’ periods and with green and blue compared to red light. Thus, we recommend lower light intensity, red colour, and shorter duration of ‘light-on’ periods as mitigation measures to reduce the effects of light at breeding colonies and in their vicinity.”

A Grey-headed Albatross guards its downy chick on Marion Island’s Grey-headed Albatross Ridge – site of a long-term monitoring colony

NOTE:  This post continues an occasional series that features photographs of the 31 ACAP-listed species, along with information from and about their photographers.  Here, Kim Stevens, currently on Gough Island in the South Atlantic, writes about her PhD research on the globally and regionally Endangered Grey-Headed Albatrosses Thalassarche chrysostoma of South Africa’s Marion Island in the southern Indian Ocean.  See species so far covered in the series in the Photo Essays section on this website.

My journey with seabirds began in 2013 when I hopped on to South Africa’s Antarctic research and supply ship, the S.A. Agulhas II, and headed south for a year-long expedition as a member of the M70 Overwintering Team to sub-Antarctic Marion Island.  Unbeknownst to me, this adventure would turn into a deep love for seabirds and the special places they inhabit.  Before this I did my undergraduate degree in Marine Biology and Ocean and Atmosphere Science, followed by a BSc (Hons) specialising in Zoology, at the University of Cape Town (UCT).  Upon seeing a job advertised to work as a seabird field assistant in the sub-Antarctic, I could not resist applying.

At Marion Island I spent the year working on several albatross, petrel and penguin species, with a specific focus on the Grey-headed Albatrosses – deploying geolocation and GPS tracking devices on them to understand where they go at sea during and outside of their breeding season.  I used these data towards an MSc on returning to South Africa, whcch I later upgraded to a PhD with UCT’s FitzPatrick Institute of African Ornithology to incorporate an analysis of the species’ long-term population dynamics.  A few months after upgrading I returned to Marion Island for a second expedition over 2016/17 (M73) to collect more data.  It was on this second expedition that I was unfortunately greeted by many a Grey-headed Albatross chick with large wounds inflicted by introduced House Mice Mus musculus and it was part of my job to record and monitor them.  It was difficult to see these chicks, so close to fledging and so badly affected by mice.

Since then, I have continued my PhD journey grappling with data, with some short sea-birding stints in between, including volunteering as a seabird observer for BirdLife South Africa’s Atlas of Seabirds at Sea (AS@S) on a winter research cruise to the Antarctic sea ice.  I also assisted researchers from the South African Department of Forestry, Fisheries and the Environment (DFFE) counting and deploying tracking devices on Snow Petrels Pagodroma nivea and Emperor Penguins Aptenodytes forsteri in Antarctica.

When the exciting opportunity arose to play a role in the Gough Island Restoration Programme (GIRP) to rid that island of its albatross and petrel-attacking House Mice and protect its many threatened seabird species, I put my PhD on hold.  I am currently working – for a two-year stretch - as the Senior Field Assistant for the Royal Society for the Protection of Birds on Gough.  And now that the project is in its final phases, we wait with bated breath to see how the seabird populations recover and for the final call on the success of the project which will be at least two years from now.  It has been an invaluable experience and the knowledge learned through this project will inevitably help the seabirds of Marion Island, which include the wonderful Grey-headed Albatross.

Second sighting: an Indian Yellow-nosed Albatross on Gough Island; photograph by Amy King

ACAP Latest News has previously reported on the first record of an Indian Yellow-nosed Albatross Thalassarche carteri (Endangered) on Gough Island in the South Atlantic, photographed ashore in January 2019.

Members of the Gough Island Research Programme based on the island have now made the second sighting on 17 September 2021 of an Indian Yellow-nosed Albatross as reported on the project’s Facebook page.  The vagrant albatross was seen and photographed in the same area where the first bird was observed, suggesting it could have been the same individual (noting that both birds were in adult plumage and that neither was banded).  Indian Yellow-nosed Albatrosses breed only on islands in the southern Indian Ocean.

The 2020/21 breeding season of globally Endangered and nationally Naturally Uncommon Northern Royal Albatrosses Diomedea sanfordi in the mainland colony at Pukekura/Taiaroa Head on New Zealand’s South Island has been a record one with 30 chicks now having fledged.  The last chick took flight on 03 October 2021; the first having left around 6 September.  A total of 41 eggs (the second highest number of eggs recorded) had been laid of which 36 hatched, giving a hatching success of 87.8% (click here), and an overall breeding success of 73.2%.

The second-last chick to fledge was the one that has been under observation by the live-streaming ‘Royal Cam’.  Named Tiaki, the female bird has been fitted with a GPS satellite tracker, the first chick to be tracked from the colony.   Those interested can follow her at-sea movements here.
