do scarecrows work?

I have a lot of strawberries this year. I am going to need some way to keep the birds out of them. I'm considering netting but it will make it difficult to pick them. I'd like the CD idea! I have a lot of old CDs I need to clean out. It only needs to work for aboiut a month while the June bearing strawberries are ripening.
