When I lived in Alaska, The crows would strip my cherry trees.
Once I put netting on them, I never had a problem.
It worked wonders for me. You can also reuse it for many years.
Your local nursery can order it for you.

Well, the answer is probably: it depends.

I have a lot of birds that nest around my house. Last year was our first summer in the new place and I _thought_ my cherry trees might be Rainier because as soon as they started getting that blush they all dissapeared ;( but this year I netted them and turns out they are Bing... just never even got close to maturing before the birds got them.

So if you have a fair number birds around and you want some or any fruit then you might want to think about netting the grapes. Not so sure if they will bother the larger fruit.

I have apricot, peach and nectarine trees fruiting for the first time this year. As a precaution, I hung old CD's from string from a few of the branches around each tree. The CD's flash brightly in the sun and wind movement and scare away birds.

Not necessary for apples or pears. very necessary for cherries and, while not trees, strawberries, blackberries and raspberries

I have to net anything I want to eat. I grow blueberries around the yard without nets for the birds and keep my rows covered. The biggest problem is the way birds, snakes and box turtles get hung up in the netting and die in the heat. I want to devise a way to sew a section of outdoor tough fabric along the bottom edge of the netting (like 2 feet worth) to form a buffer between the netting and the ground. You can find bird netting at most garden centers and it is sold online through farm supply catalogs.

It broke my heart when I found a dead mother flicker in my bird netting a couple of weeks ago. Her babies got my attention but it was too late to rescue mom. I removed the netting till I can figure out something else.
