Leaning Telegraph Poles

My thanks to Richard Webber for sending in this photo. The telegraph poles in this picture are leaning from the southwest to the northeast. This is in line with the prevailing wind, which is easy to tell in the photo if you look at the straggly bits that have been combed over at the top of the hedge.

The question is, is this a coincidence or the cause?

Please could anyone pass on any observations they have of leaning telegraph poles and together we may be able to forge a new technique.
