Why birds don't get an Electric shock?

Whenever you go outside in the parks, gardens or any market you enjoy the birds chirping, sitting on the electric wires etc. But have you ever imagined why the birds don't get an electric shock while humans get shock.

Well i should tell that its not that birds might be having a natural insulator which insulates them from getting a shock which humans lack.  God has created all of us same. Its only that they sit in such a manner that they don't get a shock.

Its all about science; before moving ahead one should know how one gets shock.We get shock when electric current passes through our body and passes it further to the ground. When we touch an electric wire it transmits current into our body and due to presence of large amount of water and iron in hemoglobin our body conducts current and create a circuit by transferring current to the earth.  This is commonly called earthing in which a metal plate is inserted deep inside the earth to transmit current to the ground from the various live wires.This is why you are asked to wear rubber slippers while touching live wires as it breaks the human circuit from the ground.

But when a bird sits on the wire it is not conducting electricity as it is not completing the circuit. If you carefully see bird always sit on a single wire if by chance its tail touches the other wire then it completes the circuit and the bird is dead. This is the reason why many monkeys and big birds like peacocks die due to electric shock as they are able to complete the circuit.

So it just that to allow the current to pass through ones body circuit has to be completed. One who completes the circuit will get shock one who do not will enjoy...
