Air cannons will start scaring birds Monday

VANCOUVER — The annual war against the starlings will resume on the Interstate 5 Bridge on Monday.

Starting Monday and continuing through March 17, Oregon Department of Transportation workers will use propane-powered orchard cannons to scatter the pooping hordes from the twin spans’ bird cagelike girders.

The nonlethal cannons will operate 43 days for about two hours each day in the late afternoon and early evening. The blasts will occur as often as once every 15 seconds.

The starlings are an invasive species whose droppings cause maintenance headaches for bridge-tenders and motorists alike.
