I know that when a bird is sitting on a high-voltage power line, virtually no current flows through the bird because there is (almost) no voltage drop between its legs, the two points are equipotential (as discussed here: How much of current flows through a bird sitting on a power line?)
I wonder what happens though,in the exact moment when the bird lands on the line, as there is a potential difference initially, so for a short time there is a current flowing. I think electricians working on high power lines (e.g. descending from a helicopter) wear a Faraday suit to prevent this sudden charging up from causing harm.
Does this affect birds landing on high-voltage lines?
