I use netting now after, like you,I ended up feeding the local blackbird population with my lovingly grown cherries. I use a net that has a very close 'weave' not even insects can get through so no birds could get tangled in it. I net it when all the fruit has set but not started to colour it doesn't look very pretty but it's only on for a few weeks and it's worth it to get to taste the fruit yourself. I've just harvested mine and they were far too delicious for bird food.
