Mostly they're red, sometimes (I think, if I remember correctly) they're yellow or orange. THey are about the size of a basketball. I have seen them in areas that make me pretty sure they are NOT there to prevent aircraft from hitting the lines. Please help!! This is driving me crazy! (Please forgive the random categorization, I really didn't know where to put this question).

and also for helicopters - it's a visual aid
helicopters go up and down - and sometimes a field is a great landing zone for Life Flight!
and it's very good to know where those puppies are
since a tower took down a life saving helo in St Petersburg a few years ago

Not just planes and helicopters, but birds too.
They started installing them in areas not frequented by aircraft to help the re-population of the california condors. They were hitting the power lines.

You will only really find them in areas that are designated landing strips or areas for planes or emergency helicopters.
So, yes, they are there so that pilots can clearly see that there are powerlines nearby and where they are located.

To keep low flying planes from hitting them
