An H5N1 avian influenza outbreak is affecting gulls across Northern Norway, with detections in multiple Troms and Nordland municipalities. Authorities warn mortality may be undercounted and urge reporting of sick or dead birds and strict biosecurity for poultry.

Avian influenza was confirmed in four seagulls in Tromsø, Norway, prompting authorities to advise the public against handling dead or sick birds without protection.

Reykjavik's Animal Services has collected dozens of dead bird carcasses, suspected to have died from avian flu, and at least two cats have tested positive for the virus.

Iceland's Food and Veterinary Authority has advised the public not to handle sick or dead birds due to an avian flu case (H5N5) in a seagull.

The Icelandic gyrfalcon population is at its lowest, with many nests empty, likely due to a higher than estimated impact of bird flu.
