A re-post from last year:
The big problem around here 
with raspberries, as with cherries and strawberries, is that the birds get them just before they are fully ripe. Or worse, they just peck the red parts off the ripening berry, and leave the rest.
It really isn't hardly worth the effort, but one perseveres. Life cannot be entirely economics-driven.
Especially Catbirds, but Robins too. Nature sure can be annoying sometimes. We grow three varieties. The birds seem to prefer the big fat French dessert variety. They might be stupid, but they aren't stupid.
I have heard that it's a good idea to plant some mulberry trees around, to keep the birds busy. I had a couple, but I had to cut them down because they were shading the garden. Ya sometimes can't win.
Even the dog doesn't deter them. I'll try the plastic owl, but they'll get used to it in a day or two, and perch on its head.
The only thing finer than a handful of sun-hot raspberries is a sun-heated Beefsteak tomato, but we won't have them for another month. That's one thing the birds will leave alone, but in a dry August, the squirrels and chipmunks will bite hunks out of them for liquids. The simple solution is to grow lots of tomatoes, but the simplest solution is to give up. But that is no fun at all. Man vs. Nature.
