Protecting fruit from birds/squirrels

So interestingly it seems to be red fruit around here that get ransacked. I grow black currants and gooseberries for us, and red currants for the birds. I feed the garden birds regularly at a different part of the garden to the fruit and veg and under their feeders I grow strawberries which are mainly for them. Our hedges also have occasional fruit bushes in them for wild life. We lose some raspberries but am planning on planting more golden varieties as they seem to get got less. I don't often net things especially if we're not going to be around to check them daily. Pigeons tend not to be a problem and the only thing our squirrel seems to do is Bury horse chestnuts everywhere.
