This works, but it's not a permanent solution. If the birds hear the bird
of prey enough times without ation they will eventually ignore the sounds.
That is unless they actually run into one. Then they will bear the sound
again for a while.

If a few of the birds should suffer an accident they will soon leave and may
not return for a long time.
