Thanks to Pete Tallman for the suggestion about Gourock golf netting. I
contacted Gourock (www.gourock.com) and asked whether their netting
would resist being torn by birds or squirrels. Here's their reply
(within a couple of hours, by the way.)

Hello Louisa, thank you for writing us!
We do have netting that can protect your blueberry bushes. It may be too
heavy to just lay over the bushes and would need a frame to hold it
up.The netting you would use is our
#15 3/4" diamond mesh. This is a long lasting net that birds could not
tear up. We have never heard of a customer having problems with
squirrels chewing up the netting.
Please open this link to our web site for prices and more info.
