In reality I think the presence of a nearby ground plane (the ground)
plus the fact the helicopter is longer than 2m and has lots of sticky
out bits is likely to push the current a fair bit higher.
Plus some of those lines you speak of may be higher than 440kV.
So on that basis, whilst a small bird can sit on an HV line, if an
ostrich got up there, its feet would probably tingle
See plenty of birds on 11kV and 33kV lines but I don't think I have
ever seen any on the higher voltages. I suppose they must sense the
electrical field as they get close.
