(BEEBE, Ark.) -- Blunt-force trauma is to blame for causing thousands of red-winged blackbirds to fall from the sky in Arkansas on New Year's Eve, according to a new report released Wednesday by the Arkansas Game and Fish Commission.
After testing 13 of the birds, scientists were able to rule out "bacteria, viruses, heavy metals, pesticides and avicides (chemicals used to kill birds) as causes of death," the commission said on their website. Tests instead indicated hemorrhaging "consistent with blunt trauma."
"In most instances, such traumatic injuries in wild birds are due to flying into stationary objects such as trees, houses, windows, power lines, towers, et cetera," the report said.
According to officials, an estimated 5,000 birds plunged to their death on Dec. 31.
