Investigation finds no evidence birds were killed

OAKLAND, Calif. (KGO) -- A US Fish and Wildlife investigation has found no evidence that federally protected birds were killed outside a post office in Oakland.

There were reports that some black crowned herons were killed during tree trimming May 3 and maybe even put into a wood chipper.

US Fish and Wildlife investigated by checking video, talking to witnesses and inspecting the wood chipper.

The agency released a report saying there's no indication the birds were killed, but it's still investigating.
