543 and still counting. Have never used playback and never will. I
occasionally pish, but I mustn't be doing it right, as I have not
found it really that effective. I find that being quiet and
inconspicuous (even to the point of using an AusCam scrim poncho and
hat cover. At least it gives the bird something to laugh at) works
much better.
Cheers,

Anyone with 500 species that's never used tapes? How about 600? 700?

If birds stop responding to playback then that's true. But if they
stop
responding to real calls from their own species then it should affect
their ability to maintain territory, breed, etc, shouldn't it. No
idea
if that happens.
I think the main thing is to make sure that birds aren't exposed to it
to much, as they can obviously survive the occasional playback. The
problem is knowing how much they've already been exposed to.

3) The other observation that some bird species seem to
habituate to the playback (and thus fail to respond to it) is
no different to them habituating to any other sound or
visible intrusion that comes their way, ie, vehicular sound
and motion. Surely this habituation must save energy rather
than expend it. It's often only when a vehicle stops rather
than passing by as usual that birds take fright and fly for
cover. Again, annoying for the hopeful observer, but hardly
any more stressful for the birds than if some normal predator
approaches.
