I need to keep the birds away without hurting them.
Do you have experience with playing non-stop predator sounds?
Does it work in the longer term?

Do you have advice on which predator sounds are best?
And how frequently (non stop or intermittent)?

As an alternative, try what I do. I take unwanted compact discs, drill
a small hole near the edge and hang them from trees with kite twine.
They spin in the slightest breeze and flash sunlight. However, I do
this only when my fruit is almost ripe because the birds will eventually
get used to the flashing light.

For squirrels, I take an old sock, put a small handful of blood meal in
it, and tie it to a tree. I do this with several socks. Squirrels will
not go where they smell blood. This should also work to discourage
deer. NOTE: This will definitely NOT work with rats or raccoons.
