Dozens of dead birds have been found lying in a residential street in Sweden, days after thousands of birds fell to their deaths in the US.

Police in the town of Falkoeping have told Swedish media that between 50 and 100 jackdaws had died.

Some are said to have been hit by cars but others have no visible injuries.

Parallels have been drawn with the mysterious death of about 3,000 red-winged blackbirds in the US state of Arkansas on New Year's Eve.
