Why Birds not feel electric shock on wires ?

 Most of us see birds sit on the electrical wires and do not feel electric current the simple anwer of this question is this

Current is always flow from high potential to lower potential. When the positive and negative wire are in contact the current flow through it but in case of birds they are sit only in one wire for example if crow sit in wire they have no contact with the ground or neutral wire that’s why they can not complete the electric circuit to flow the current in it. You also see when they touch with the other wire they are die. The reason behind this is that the crow are now in contact with the negative and positive wire that’s why current will flow through it and they are die.
