On Wednesday, in Schönbrunn Zoo Reports H5N8 Infected Pelican, we learned that the world's oldest zoo detected HPAI H5N8 in a single sick Dalmatian Pelican which was part of a larger exhibit which had been kept under cover since December.
Testing of the remaining birds - all apparently showing no outward signs of infection - was underway with results expected on Thursday.
Overnight those results came in, and as the following (translated) statement from the Vienna Zoo Website informs us, the rest of birds tested positive as well.
