Another piece of research from team #Shag on Sklinna. Strongly recommended for all researchers working with #biologging data

Rest in peace, Jane Goodall! You made the world a better place. Let's try to follow Jane's footsteps and inspiration and try to make a difference. The right kind of difference!

New report out on kelp / brown seaweed harvesting. After many years of harvesting there is still very little we know...

#birdwatching on #OctoberBigDay - 51 species and > 2000 individuals. Not a bad result for October in central #Norway. A lot of migrants have left already - no surprise, as we were met by crispy cold temperatures, but blue sky. ebird.org/tripreport/2...

Birte Maaseide collecting a faeces sample from a shag chick in the colony at Sklinna, central Norway.

Birte Maaseide collecting a faeces sample from a shag chick in the colony at Sklinna, central Norway.

New article on #plastics in #faeces samples of shag chicks. 25 out of 36 samples contained microplastics > 100 Β΅m; we found 17 particles per g dry mass and clear evidence for parental transfer of plastics.

β€œFine-scale foraging behaviour of European Shags in kelp forests"

@ninadehnhard.bsky.social reveals that European Shags spend 83% of their dive time in kelp forests, emphasizing the critical role of kelp habitats in their foraging. 🌳

The fieldseason on Sklinna was a success also this year. Lots of data collected, lots of loggers deployed. Want to know more? - read my blog post:

GPS #biotracking of #shags on Sklinna done for this season. We got 59 of 60 trackers back. GPS & dive loggers help us identify important foraging areas, critical for marine spatial planning. #seabirds #mpa @seapop.bsky.social

#European πŸ‡ͺπŸ‡Ί #elections today. I hope many of my friends in Europe are going voting today/ have voted already for a strong, peaceful and united Europe, and against nationalist interests that are splitting what has taken so long to build. My #vote went in by letter a few weeks ago

Another encounter with #fishing nets that are killing #seabirds. We couldn't save the shag anymore, but the guillemot got to live. #fieldwork at Sklinna #Norway for @seapop.bsky.social

Kittiwake count in RΓΈrvik. #Seabirds #fieldwork for NINA & @seapop.bsky.social. Looks like the #avianinfluenza outbreak last year had no major impact on this population #HPAI #H5N1

Hvorfor forsvinner fuglene fra fuglefjellene Syltefjord, Runde, RΓΈst og HornΓΈya? PΓ₯ 50 Γ₯r har 8 av 10 fugler forsvunnet fra de norske fuglefjellene.

Great #scicomm project led by my colleague Signe Christensen-Dalsgaard illustrating the dramatic declines of #seabird populations in Norway.

Agreement on the Conservation of Albatrosses and Petrels - High Pathogenicity Avian Influenza has spread to Wandering Albatrosses on sub-Antarctic islands Dr Richard Phillips is Head of the British Antarctic Survey’s Higher Predators and Conservation Group and Vice-convenor of ACAP’s Population and Conservation Status Working Group and has been working with albatrosses and petrels in the region for over 20 years.

Terrible news from South Georgia: #HPAI has spread to Wandering albatrosses and killed at least 50 adult birds. #seabirds #avianflu www.acap.aq/latest-news/...

Journal of Experimental Biology, A framework to unlock marine bird energetics.
A myriad of BMR multipliers -> An easy-to-follow framework -> Exciting new energetic insights.
We compiled BMR multipliers for you to combine with your data, using our framework to calculate the energy expenditure of any bird.
In the background is a figure illustrating the different marine bird families, their ecological guilds, and whether BMR multiplier data are available. There's also an illustration of a great auk eating a fish.

#NewPaper providing a framework that YOU can use to estimate the amount of energy that any population of marine bird (e.g. #seabirds, ducks, & divers) uses day-to-day.

It was a pleasure to co-lead this with my PhD pal Jamie Duckworth 🐦

New-ish paper! Published last month (I was on holiday!) alongside Hannah Wood, @ruthedunn.bsky.social, @robinfreeman.bsky.social, and others πŸͺΆπŸ¦‘

Red-footed boobies showed colony segregation in foraging range, space use, and timing
