Mass mortality among colony-breeding seabirds in the German Wadden Sea in 2022 due to distinct genotypes of HPAIV H5N1 clade 2.3.4.4b.

Mass mortality was observed among colony-breeding seabirds in the German Wadden Sea area of the North Sea during the summer months of 2022. Several species' colonies were affected, most notably sandwich terns (), common terns () and Germany's only northern gannet () colony on the island of Heligoland. Mortality in some tern colonies reached 40%, while other colonies were almost spared.

Draft Genome Sequences of Vibrio cholerae Non-O1, Non-O139 Isolates from Common Tern Chicks () following a Mass Mortality Event.

is an inhabitant of aquatic environments worldwide. Here, we report the draft genome sequences of eight non-O1, non-O139 isolates that were recovered from the corpses of two seabird chicks (common terns) following a mass mortality event in a German breeding colony in 2019.
