It's -12°F here. Every time it gets this cold a few bald eagles come down from the mountains and perch on the electric poles on my back yard. Today it is only one but we've had up to three at a time.

How does a single-wire electric pole work?
The image is cropped. I believe that line is telephone. The electric lines are below.
Right... I'm kinda dumb lol
Actually not as dumb as you think. Single wire earth return transmission is a real thing
