Crows attacking cops in Everett

Crows have been attacking cops in the parking lot of the Everett Police Department's north precinct station. Birds have been swooping down on officers walking from their cars.

The Daily Herald reports one officer tried to use his siren to scare the crows away. They responded by decorating his car with droppings.

State Fish and Wildlife Department biologist Ruth Milner says the crows are protecting immature birds that are helpless on the ground.

City spokeswoman Kate Reardon says police and other employees who have been attacked have agreed to give way to the crows and wait out the aggression. People may use umbrellas for defense.
