The Marquette Tower in downtown Marquette, Missouri used to be home to dozens of roosting pigeons. Their waste and noise was becoming a nuisance to pedestrians in the area so authorities are now employing two non-traditional methods to get rid of the birds.
A large device broadcasts the sound of birds in distress over the rooftops. And ‘spiders’, metal poles that move in the wind or when pigeons touch them, have been installed. Since installation, the number of pigeons roosting in the area has dramatically dropped.
