The Arkansas Game and Fish Commission said Saturday more than 1,000 dead blackbirds fell from the sky in Beebe.
The agency said its enforcement officers began receiving reports about the dead birds about 11:30 p.m. Friday. The birds fell over a one-mile area of the city, and an aerial survey indicated that no other dead birds were found outside of that area, officials said.
Robby King, a wildlife officer for the agency, collected about 65 dead birds, which will be sent for testing to the state Livestock and Poultry Commission lab and the National Wildlife Health Center lab in Madison, Wis.
Commission ornithologist Karen Rowe said that similar events have occurred elsewhere and that test results "usually were inconclusive."
The birds showed physical trauma, said Rowe, who surmised that "the flock could have been hit by lightning or high-altitude hail."
The agency also said another possibility is that New Year's Eve revelers shooting off fireworks in the area could have startled the birds from their roost and caused them to die from stress.
It's doubtful the birds were poisoned, Rowe said, "since it only involved a flock of blackbirds and only involved them falling out of the sky." She said a necropsy is the only way to determine if the birds were poisoned.
The city of Beebe hired U.S. Environmental Services to clean up and dispose of the dead birds.
