City of Watertown residents could see and hear attempts to disperse crow flocks for two nights this week.
Wildlife biologists from Loomacres Wildlife Management will be out Tuesday and Wednesday evenings to shoo crows out of residential neighborhoods.
Crows gather in large flocks around the city and cause problems for property owners.
The biologists use pyrotechnics, lasers, air rifles, and other devices to try to break flocks up into smaller, less destructive groups.
Officials say people shouldn't be alarmed by the bright lights and loud noises.
If you know where flocks are, you can call 1-800-243-1462, extension 1. Or you can go www.airportwildlife.com/crows.php.
Loomacres uses the information to target their hazing efforts.
