The first case of a walrus dying of bird flu registered on Svalbard
“Last year we got several reports from tourists and scientists that they saw around six walruses dead here on the west side of Svalbard. Unfortunately, we couldn’t sample them as the dead walruses drifted away by the time we got to the place. But it’s not normal to get so many reported dead walruses in such a small area," said Christian Lydersen, senior scientist at the Norwegian Polar Institute. Now samples (collected by a Station Manager in July 2023) have tested positive for highly pathogenic avian influenza.
