Watertown city leaders got an after-action report Monday night from the company they hire to deal with pesky crows over the winter.
Shawn Ferdinand from Loomacres Wildlife Management laid out the numbers.
He said the company used pyrotechnics and lasers to harass nearly 88,000 crows this past winter. Two of those crows were killed.
Roosting crows can cause serious problems.
"Generally we're just trying to keep them away from parking lots, peoples' buildings," he said. "The defecation that they can produce -- it's very acidic and it can cause damage to shingles and cause damage to paint on cars."
Ferdinand also said Loomacres could use other tools to scare the crows, such as cap guns and fire snappers, but says they are not recommended inside city limits.
