Good Questions: Pigeon Mufflers?

Hello AT,

Sitting on my sofa here with a friend who asks, "How do I get rid of the vocalizing pigeons who make themselves at home on my window sills in the shaftway of my building?" I have no PETA friendly counsel to give and am hopeful you and the readers of AT can provide some insights.

Thanks, Andrew
