According to environmentalists, birds killed or injured include such endangered migratory songbirds as the black rail, Bell's vireo, the golden-winged warbler and Henslow's sparrow. Most songbirds fly at night and orient themselves via starlight. In bad weather, birds often mistake tower lights for stars. The birds keep circling until they collide with the tower, support wires, or each other. The problem is that birds are sensitive to magnetic radiation to the point where microwaves interfere with their sensors and misguide them while navigating. Environmentalists have urged cell phone companies to install bird deterrents to save the birds.
Then there's the damage birds inflict on the towers. Bird droppings can corrode copper fittings and connections and thus interrupt service. They can also corrode supporting braces and structures and damage plastics. Bird nests can plug rain gutters and vents, which can lead to water damage and short circuits.
Another problem with bird droppings on cell phone towers is that the droppings carry diseases. Maintenance workers can become seriously ill when they disturb dried droppings and nests and inhale the dust, bacteria and spores that live in bird droppings.
Finally, bird droppings can cause potentially lethal slip-and-fall hazards as maintenance workers maneuver around cell phone towers—some of which are in dangerously lofty perches. The right bird deterrent can keep pest birds away from these towers.
One way to discourage pest birds from avoiding cell phone towers is through the use of Plastic Bird Spikes. Plastic bird spikes are made of a rigid polycarbonate plastic. They are U.V. protected and non-conductive, making them ideal for installation on cell phone towers. Plastic bird spikes come in a variety of colors to match the towers, so once installed they will be virtually invisible. The best plastic bird spikes will come with a 5-year guarantee making them one of the longest lasting bird deterrents on the market.
