My local garden store recently sold me some tape to scare away the birds, I think its called flash or reflective garden tape. It looks a bit like a roll of thin strips of tin foil which you tie to your plants and the refection is suppose to scare away birds. So far in comparison to other years
growing strawberries without the tape I have lost far less fruit, once in a while a few go missing here or there but the majority of the crop has been safe from birds.
I also use for my larger plants netting you throw over plants that are suppose to keep fruit from being picked by birds, I got one for my raspberry plant a few years back and I remember home depot selling netting for strawberries and low
growing fruit. The netting openings are large enough for light and water to get through but not big enough for birds and other small animals to get to the fruit.
