MAYPORT, Fla. -

There was no evidence of injuries inflicted by humans to 12 pelicans found injured and emaciated in Mayport late this past winter, according to the Florida Fish and Wildlife Conservation Commission.

Investigators performed necropsies on the ones that died.

Residents in the area said they started seeing the dead birds in January.
