Agree with ChrissieB here. We had the same problem with our Morello Cherry until I gave it a good spraying in late Winter before the leaves appeared with a Winter Wash (Soft horticultural soap preparation).
Our Stella has done far better with another set of Cherry trees near by. However it still does not stop the birds from taking the fruit when they are still white!
