Another piece of research from team #Shag on Sklinna. Strongly recommended for all researchers working with #biologging data
#biologging #research is booming - but do #loggers actually impact the birds? Yes, they do - depending on the mass and attachment location. If you work with biologging, you should read our latest publication seapop.no/en/2025/11/l...

Loggers attached to birds can affect foraging behaviour
Loggers have become a central part of research on seabirds and other groups of animals over the past 20 years. In seabird research, loggers provide very useful documentation of diving behaviour…

New report about seaweed harvesting on possible effects on #seabirds and #shorebirds from @ninadehnhard.bsky.social & colleagues at Norwegian Institute for Nature Research. GPS #tracking data from SEAPOP showed overlap in area use for some coastal seabird populations with areas that are trawled.
Er høsting av tang og tare en trussel mot fuglelivet?
Kommersiell høsting av viltvoksende tang og tare er en viktig næring langs norskekysten. Tang og tare er et uunnværlig råstoff i en rekke industrier, fra matproduksjon og dyrefôr til legemidler og bio...

#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...

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

“Fine-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. 🌳

Oljesøl dreper utrydningstruede sjøfugler i Finnmark – jakt på kilden til utslippet
Tung, seig olje har rammet hundrevis av utrydningstruede sjøfugler i naturreservatet på Hornøya i Finnmark. Ingen vet hvor dødsfellen befinner seg i havet.

Hvorfor forsvinner fuglene fra fuglefjellene Syltefjord, Runde, Røst og Hornøya?
På 50 år har 8 av 10 fugler forsvunnet fra de norske fuglefjellene.
