It was at the beginning of last week that a swan chick lay dead on the ice in Gustavsberg harbor. It was surrounded by siblings and a variety of other seabirds, wrote Mitti.
On Wednesday night, two more swan chicks died.
"It was a very quick process. One day they were lively and the next day they were dead," Lili Päivärinta, who runs the Djurens ö foundation, told the newspaper.
The dead birds were taken to the Swedish Veterinary Institute (SVA) for testing, and tests showed they were infected with bird flu.
Since last autumn, several cases of bird flu have been confirmed further south in the country, but the swans on Värmdö are the first confirmed cases in Stockholm.
