We sitting on electrical wires high up the air.

We know what danger electricity brings. Starting
the moment we’ve been raised, our parents had introduced
to us the safety precautions when it comes to electricity.
For instance, we are not allowed to place our fingers into
electrical outlets or to use electrical appliances near water.
That schema of ours may have perplexed us as
we roam beyond the corners of our home. We saw squirrels
running along the electrical wires. Some even lies
there for longer period of times. And the most often scenario
we have seen for almost every day are the dozens of
birds sitting on electrical wires high up the air.
We hear no screeches as we keep an eye on
birds sitting along those electrical wires high above. There
are no puffs, smoke and feathers either. Also, no birds get
fried or fell on the ground because they have been electrocuted.
But why do this happens? Why do birds don’t get
shocked, while human does?
By definition, electricity is the flow of electrons
by dint of conductors. Electrical wires are made up of copper-
a great conductor of electricity that permits this to
flow easily along the surface. Electricity flows by the channel
where there is only a lesser amount of resistance.
Birds do not get electrocuted, simply because
they are not good conductors of electricity. Birds’ cells and
tissues do not offer electrons an easier route than the copper
wire. Thus, the electricity bypasses the birds and keeps
flowing along the wire instead.
Another reason also why electricity circumvent
the birds is that there is no voltage difference in a single
wire. Electrons do move only when there is a difference
among electrical potentials. In particular, areas from high
voltage to low voltage are where electricity flow. And it
continuously flowed bypassing those paths of least resistance
and those birds whom are not good conductors
until it meets difference in voltages.
Nevertheless, there are also instances that
birds can be electrocuted. One vivid example is when a
bird touches the ground or flap its wings and touch another
wire with a different voltage. This happens because its
body would now become a path of electricity to reach either
the ground of no voltage or a wire of different voltage.
To sum up, the reason why birds can harmlessly
stand on power lines is not just because they are not good
conductors of electricity. But this is also because of the
power lines which tend to be high in the air with plenty of
space between the wires to avoid having electrical potential
difference. Remember that even if the birds’ electrons
won’t allow an easy way for electrons to flow, still however,
if there is a difference among voltages, birds can still get
shocked.
