With two exceptions, conductors are not usually physically damaged by animals. Squirrels, however, will chew secondary conductors to shreds and the aluminum connectors as well. Flying squirrels will nest in URD guards and chew away the conductor insulation. Occasionally, squirrels (actually, other animals as well) will cause a short circuit by contacting a phase wire and a wet crossarm or pole. Rats and mice have an insatiable appetite for insulation, almost as if they were addicted.

Some raptors, birds of prey (eagles, hawks, ospreys, owls, vultures), are large enough to cause a phase to phase or phase to ground wingtip contact when flying through the conductors. There is growing concern with birds (particularly raptors) in flight colliding with conductors. If you are having a problem with conductors and raptors, please read this...

The most common problem with outages and conductors seems to also involve birds. A number of utilities have reported outages occurring when a flock of birds have been perching on the conductors. The force of the birds flying off at the same time can sometimes push the phase wire into the neutral or nearby trees and shrubbery.
