Watch Blackbirds Fall From Sky In Arkansas : More Than 1,000 Dead Blackbirds.

BEEBE, Arkansas -- Wildlife officials are trying to determine what caused more than 1,000 black birds to die and fall from the sky over an Arkansas town.

The birds had fallen Friday night over a 1-mile area of Beebe, and an aerial survey indicated that no other dead birds were found outside of that area. The workers from U.S. Environmental Services started the cleanup Saturday.

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.
