PORTLAND, Ore. (AP) — A wildlife official says tests have confirmed that a pesticide killed more than two dozen crows found in downtown Portland, but investigators still can't say whether the birds were poisoned intentionally.
The Oregonian reports (http://is.gd/S2n6Sj ) that Brent Lawrence of the U.S. Fish and Wildlife Service's Office of Law Enforcement said Wednesday that investigators are still trying to determine "what happened, where it happened and whether any illegal actions were involved."
Crow carcasses were analyzed after the Audubon Society of Portland and other groups collected the bodies of crows that had been reported to be suffering from seizures before dying at three downtown parks on Nov. 26.
The fish and wildlife service says a pesticide commonly used to control nuisance birds caused the crows' deaths.
Crows are protected under the Migratory Bird Treaty Act.
