CLEARFIELD -- Utah Division of Wildlife Resources officials now know what caused hundreds of birds to die in Clearfield a week before Christmas; however, there are still several unanswered questions.
Phil Douglass, the DWR conservation outreach manager for Northern Utah, said the toxicology results -- received Wednesday, from birds sent to a lab in Logan -- show the birds died after being exposed to Starlicide, a poison used primarily for starling population control.
"The thing that's tricky about the situation is there are two formulas of this Starlicide. One is commercial grade (used by the government) and the other is public grade, and there is no way of determining what grade it was," Douglass said. "So we know what it was, we just don't know where it came from."
