Italian Diego Fenicchia was driving in the capital Rome early Friday when he saw dead birds on the streets.
"Guys, this is the filth of humans, the fireworks, hundreds of dead birds, hundreds. Hundreds of dead birds on Via Cavour. It's embarrassing, it's sad, incredible, incredible, my happiness has already gone away," Fenicchia said as he filmed the images near a metro station in Via Cavour and uploaded on his social media account.
It is unclear exactly how the birds died, but in a post on their Facebook page the International Animal Protection Organization attributed it to fireworks.
The mayor of Rome had prohibited fireworks from December 31 to January 6. But thousands were still set off on New Year's Eve.
