How can birds sit on electrical wires without getting a shock?
In order to receive a shock from an electrical source a circuit must be completed (+/-), and this happens when a positive flowing electrical wire meets something grounded. Since a bird flies up to a wire it is not grounded and therefore is not shocked. An electrical circuit can be made by connecting 2 wires with an electrical current. There are large birds with wide enough wingspans that touch or come too close to two separate electrical wires and have been electrocuted or injured badly enough to make their natural survival impossible. Large birds, such as birds of prey, often meet their demise in this fashion and some you’ll see at your local zoo or wildlife rehabilitation facility.
