Someone intentionally set off fireworks under a blackbird roost in Beebe, Arkansas on New Year's Eve, killing about 200 birds on the first anniversary of the similar death of 5,000 of the birds, authorities said on Monday.
"Fireworks were found at the roost so we know it was intentional," said Ginny Porter, spokeswoman the Arkansas Game and Fish Commission.
She said about 200 birds died of blunt force trauma after they were spooked by the explosion and slammed into trees, houses, cars or one another.
