Scott, You may want to try a different color paint.

Check out these references.  While I have not found any reference, I bet ripening berries and fruit that are subject to bird depredation probably increase UV reflexivity as they ripen.  I would try a fluorescent paint.

I
 should say I tried the painted rocks trick for my strawberries and  
the birds were not fooled, alas. They were pretty convincing I
thought, I grabbed for those rocks I don't know how many times when I
was picking berries. It probably depends on what type of birds you
have.

The birds are now pecking at my Santa Rosa plums and it is making me a
bigger fan of yellow plum varieties, which they have been almost
completely ignoring. Putting footies on the pluots completely fooled
them, making the fruits tan and not red.

Scott
