With the development of new rural areas, large trees have almost disappeared, and birds are helpless, so magpies choose to make nests and rest on high-voltage power poles, including other birds
They themselves are insulated against electricity, especially the legs, so they won't get an electric shock. However, the bird's nest poses certain dangers to the power poles. If there are overly long branches and rainwater causes short circuits in the wires, it may cause trouble to the normal operation of the wires. Therefore, the regulatory authorities conduct regular inspections and cleanups to avoid future troubles.
There are no objects blocking the bird's view around the wire, making it easy to observe the surrounding situation and know whether the location is safe and whether there is any prey.
