Birds are still dropping out of the sky and residents in Cumberland County, New Jersey were left wondering what caused dozens of birds to drop dead from the sky earlier this week.

Residents along Peach Drive in Millville found at least 80 dead birds — mostly red-winged blackbirds — on the ground, having fallen from trees and the sky.

“Crazy — something out of a movie,” said resident Michelle Cavalieri, who saw the birds fall.

The birds caused a bloody mess on roadways in the residential neighborhood, reports MSNBC.com.

“They’d get up and try and fly and they were out of control so they’d crash and fall again,” said resident Jim Sinclair. “It was just strange.”

Animal control, public health officials and other emergency crews were on the scene Tuesday morning collecting dead birds to try and figure out exactly what caused so many of them to die.

Cumberland County Public Information Officer Troy Ferus said the birds’ death likely was caused by something they ate — a granular pesticide put down legally by nearby Ingraldi Farms.
