Hundreds of blackbirds mysteriously fell from New Jersey sky

Last month, more than 200 red-winged blackbirds dropped from the sky above Cumberland County in New Jersey. It's the second time in less than a month, and the third this year. From Philly.com:

"They just fell from the sky," said Larry Hajna, a spokesman for the New Jersey Department of Environmental Protection...

After county agricultural agents had been notified by homeowners, the DEP's Division of Fish and Wildlife arrived in Stow Creek and removed the birds, collecting some of them to be sent to a state lab for necropsy, toxicology, and histopathology tests.

But the results of all the tests were inconclusive, Hajna said last week.

"We did ascertain that the birds suffered trauma and internal bleeding from hitting the ground," Hajna said. "But what made them fall from the sky in the first place . . . we can't say for certain."

Even wheat seed from a nearby farmer's field was collected and tested for chemical compounds by the University of Pennsylvania... None of those compounds (found) is considered harmful to birds and none of the chemicals was found to be among those that are sometimes used by farmers to control "nuisance" species like blackbirds, Hajna said.
