Retired Massachusetts State Police Trooper Mike Lapointe taps a foil pan and watches it spin on the string that attaches it to the pole in his hand. The low-tech device, he explains, was intended to keep crows away from tomatoes. It didn’t work. So Lapointe moved a crow carcass into the field from the nearby road where it was killed, and that did the job.
“We hung that thing up until it was basically a skeleton and the crows didn’t come around,’’ Lapointe says.
