Aircraft mechanic with some engineering, 18 years in the construction field, 5 being a Site Super for large projects. I have opened live meter panels
and transformer boxes to check things out. Even designed a layout for all the pull boxes, splice locations, transformer locations for one site in
California. The design was approved by a PG&E engineer in about a week. Usually takes them about 3 months to come up with the site design.
There is really no way a group of birds is going to be harmed by power lines.
You are correct on the high voltage and low amperage. This is because the current sets up a "conductive" resistance in the cable. This is from
memory but it has to do with the current setting up the resistance in the cables, which is why they run high voltage-low amperage. Growing up on a
farm where we had high voltage lines, during the winter sometimes you would have thousands of birds sitting on the power lines. I believe a small
amount of heat is generated by the flow of electricity through the cables. Do not remember that formula, but remember the resistance to the flow of
electricity is R=KL/A where K is the constant or the resistance of the material itself times by the length divided by area. I would have to look in my
books to find the heat creation components. By the way, all those years on the farm never once saw a bird electrocuted on those power lines. I did get
zapped by a single phase from the manure pump though. One lead came off inside the box, when I opened the panel the wire touched the cover and I woke
up a few minutes later. Last time I ever opened a live panel without my leather gloves on though.
Anyway, sounds like just another ignorant supposition for something they do not know.
