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.
Veterinary officials told Swedish radio that the case in Falkoeping was rare although they said there could be a number of reasons such as "disease or poisoning".
Aftonbladet newspaper quoted one resident, Drilon Hulaj, who said that as he drove home late on Tuesday night the street in front of him was dotted with "hundreds of dead birds".
Mr Hulaj said he had been immediately reminded of the events in the town of Beebe, Arkansas. Scientists have said the blackbirds there may have been affected by fireworks.
There have been no reports of fireworks or storms in Falkoeping at the time.
