HARRISBURG, Pa., Nov. 16, 2016 /PRNewswire-USNewswire/ -- On Monday Nov. 21st, the Department of General Services will start the 19th Annual State Capitol Complex Crow Dispersal Program, which makes use of whistling and exploding shells to keep crows from roosting in the Capitol Complex. The program will continue daily throughout the next few months between 5-7 p.m. until the crows have been dispersed. The public is being made aware that they should may to hear whistling and exploding shells during that time frame. "The methods used to keep crows from roosting in the Capitol Complex are meant to startle the birds, but can also have the same effect on unsuspecting members of the public," Secretary Curt Topper said. "Each year, we take the precaution of alerting the public and commonwealth employees to prevent any unnecessary alarm when the program begins." The crow dispersal program helps reduce slipping hazards for pedestrians due to the increased amount of crow waste that can accumulate on sidewalks - especially in wet weather. The program also helps reduce the damage that can be done by crow waste to exterior of the buildings throughout the Capitol Complex. Pennsylvania Capitol Police will discharge exploding shells and whistling devices to deter crows from roosting. The crow dispersal program is U.S. Department of Agriculture-approved and the specific, non-lethal anti-roosting measures used are not harmful to people, crows, other animals or the environment.
