Samples taken from a white-tailed eagle found dead on a skerry near Barðaströnd in the Westfjords in mid-September tested positive for a severe bird flu virus of the strain HPAI H4N5. An eider duck that was found dead in Ólafsfjörður, West Iceland recently was infected with the same strain of bird flu virus. The strain has not been detected in Iceland before and is not common.

Such deaths are unusual at this time of year in Iceland and their cause is unknown. The widespread deaths of Kittiwakes cannot be attributed to bird flu, according to Brigitte Brugger of the Icelandic Food and Veterinary Authority (MAST). Samples from the birds analysed by MAST ruled out the illness. While bird flu is unlikely to be the cause, extreme weather may be a possible explanation.

The Centers for Disease Control and Prevention reports more than 53 million birds across the U.S. have died from highly pathogenic avian influenza. The CDC’s count of 4,000-plus infected is far from reliable. The disease contracting to people is believed to be extremely rare.

Between the fall of 2021 and the fall of 2022, APU students observed a dramatic decrease in the number of Peregrine Falcons between Eagle and Circle, Alaska.

Bird flu may be the reason behind a drastic decrease in the number of peregrine falcons in Sweden this year. Every year there is a stock count of the number of peregrine falcons in Sweden and this year early numbers indicate there may be a big drop in the number of birds counted.
