Plant Sciences, Zoology & Evolution / Could we use a high-frequency noise to scare birds away?

Paul Anderson asked the Naked Scientists:
Hi Chris and team,
You mentioned in one of your podcasts about a high pitched frequency that young folk heard and it was used to keep young folk away from a shop in the UK. I wonder if it could also be used in graffiti prone areas?
Is there an irritating frequency which could be used to keep birds from my plum tree? Perhaps it could be solar powered.
My plums ripen from the top and by the time I see that, the birds have already had a meal. I just thought this morning that perhaps if I were to surround the base of the plum tree with tinfoil, it would reflect the sunlight up and I may be able to get some uniformity in the ripening of my plums.
Can birds be divided into fruit eating birds and insect eating birds, or do they all eat both? If there is that distinction, then I would want the insect eating birds but not the fruit eating birds on my plum trees. This then raises the question of whether they are all irritated by the same or different frequencies. I suppose I could just broadcast squawks from hawks and have solar powered models of hawks waving their wings.
