The wingspan on a big bird is large enough to touch two wires at once. Any difference in voltage between the wires will cause current to flow through the bird, perhaps killing it.

Small birds can only touch one wire at a time.

How can you prevent birds from landing on power lines?

I took coils of roofing nails and uncoiled them to make a strand of nails and zip tied them,point up, to my cable and phone lines that are overhead. But would not recommend this for your homes overhead 240/120v electric line. IMO


How do birds not get electrocuted on power lines?

Actually if we were to sit on a power line and not touch anything else like the birds do we would not get electrocuted.The current a flow of electrons,flows along a path of least resistance the electrons want to get to where they are going in the easiest possible way. Electricity flows from one voltage to another value of voltage. For the birds, the power lines have the same voltage -- so the birds are safe. Don't approach power lines, because humans come from the ground, which is a sink for the current.


Do ducks commonly sit on power lines?

No, ducks do not commonly sit on power lines. They are more commonly found in bodies of water like ponds, lakes, and rivers, where they can swim and forage for food. Sitting on power lines would not be a natural behavior for ducks.


Why are the wingspans of birds a consideration in determining the spacing between parallel wires in a power line?

If the wingspan of birds is sufficient to span the wires that differ in electric potential, then the bird acts as a path for current to flow from the high voltage wire to the low voltage wire. Since the electric potential differences are huge in power lines, it is very likely that the bird will be cooked when it completes the circuit and the ground below will become littered with carcasses.


How come birds can land on power lines without being electrocuted?

The high voltage is between one wire and the other. From one point on the wire to another point on the same wire, the voltage is quite insignificant. As long as the birds don't touch both wires, nothing much will happen. The wire does not have a difference in voltage from foot to foot. The term "high voltage" refers from wire to ground. Electricity flows down a voltage gradient. There is no gradient of voltage between the feet.

Why does some power lines have red plastic balls attached to them?

That is to warn birds so that large flock of birds do not fly into the power lines. Also helicopters.

Why do birds get electrocuted on power lines?

Usually they don't.


Why is it that birds can perch safeley on high voltage electric lines but if electrical workers accidentally touched a line they would be killed instantly?

Because birds are not 'grounded'. This means they are NOT touching the power line AND the ground, at the SAME time.


Why do birds sitting on a power line not get electrocuted?

Birds do not get electrocuted when sitting on power lines because they are not completing a circuit for electricity to flow through. The electricity in power lines travels in a closed loop, and birds are not grounded so there is no path for the electricity to flow through them. Additionally, most power lines are insulated to prevent electricity from leaking out.


How crow does not get electrocuted when it sit on the electric power lines?

Birds perching on power lines do not get electrocuted because they are not completing a circuit by touching another conductor. The power lines are insulated and the birds' legs are not close enough together to create a path for electricity to flow through their bodies.

Why are large birds more vulnerable to powerlines than smaller birds?

Smaller birds can fly through the gaps in power lines and bigger birds get stuck when they try to go through.
