We have recently planted raspberries and blueberries and have had tame blackberry plants for a while now.  We're excited at the prospect of fresh fruit from our own bushes - fruit for US to eat.
I think you may see the issue here.  We love the birds.  We love the berries.  The birds love the berries.
I'll be spending a fair amount of money on bird feed AND on netting to keep the birds away from the berries.
Life can be complicated.
