300 black birds found dead along I-65, WAFF, January 12, 2011:
[T]here are scores of dead black birds, about 300 of them.
Wildlife biologist Bill Gates of the Wheeler National Wildlife Refuge said they're grackles, a native black bird. ...
"Typically large numbers of birds die from disease, from poisonings and from being hit by objects or flying into objects," Gates said. "Really you can't rule any of those out until the birds have been examined."
Gates said results from the lab could take about a month or two.
