Why can birds sit on electrical wires is a perplexing question for most people. I have often wondered myself how they can simply sit there without getting electrocuted like a person or other animal would be.
According to science, birds are actually creating the same type of electron as the power line that they sit on. However, that doesn’t mean that they are always safe. In fact, if the bird were to extend a wing or try to peck at something on a different wire than what they are sitting, it will most certainly be bye bye birdy since they are crossing the electrons.
The connection that they are creating between their feet and the power line does not conduct enough electricity to cause a disturbance. The power line is actually making a big circle from the power station to your home. The loop that is created remains unbroken unless the bird or any other animal finds a way to disrupt the flow. Once the flow is disrupted, the potential for electrocution becomes greater.
