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.
The weight of a crow varies, but on average, a crow weighs around 1-2 pounds.
I am going to hazard a guess that crowbars are so basic, so simple and useful in so many ways, that their use [levers] in one form or another goes back to the earliest periods of the human species. It would be very much the same for the wheel. Their first use is lost in the far distant ages past. The origin of the word crowbar is suspected to be from the 1400's when it was called a crow bar. It is believed that the tool was called this because the bar looks like a crow's beak or crow's foot at one end and is used the same way a crow pries open a nut.
The load is the object being lifted by the crowbar, the fulcrum is the point on which the crowbar pivots to lift the load, and the effort is the force applied to the crowbar to lift the load.
The fulcrum is the point of support on the crowbar where it pivots as you apply force to lift the nail. It acts as the lever point to help you pry up the nail using less force.
Tests have shown that both visible Red Light Therapy and Infrared light affect at least 24 different positive changes at a cellular level. Visible Red light, at wavelengths from 630-660nm (nano meters) and Infrared light at 880nm penetrates tissue and is very beneficial in treating problems of the skin such as fine lines, wrinkles, and crow's-feet.
In order for something to be shocked it must have a path to ground. If the bird is setting on a power line it is not grounded so therefore it does not get shocked. If the crow were to spread its wings to fly and get between two phases then it would be shocked because it would basically become a buss bar between two of the three phases.

The crow may seem an unlikely power animal candidate. However, the crow is regarded in Shamanist faith as a creature that transports souls out of the dark and into the light. He is also known as a "judge" of sorts, representing all things ethical and fair.

In line mode the ruler is drawn as great circles (shortest possible path), which should be as a "crow flies". The ruler in Google Earth allows measurement of distances for a straight line or paths. Note for large distances (e.g. > 2000 miles) lines are drawn different than the lat-lon grid lines in Google Earth.
