Alistair's question is an interesting one. I was trying to rack my brain to
recall if there are any species that I have not seen without using playback.
The one that comes to mind is Sooty Owl but I have certainly heard it without
using a tape, but I have seen it a number of times while doing call playback
surveys (they usually respond really well). Of the 650+ species I have seen in
Australia, this is the only 1 I can definitely not say I have not used a tape
(though I also have at least one species - Little Kingfisher - that I have only
seen in the hand while banding it). I do not use tapes to "tick" a new species
but as I think I have said before on this topic, I have no problem with using
them as part of systematic surveys to determine distribution/habitat use (as
long as the survey effort is not too high at the one location) and do so
regularly (like at the moment with Redthroat surveys).
Saying this I regularly "pish" birds in which I would have thought is a
different reaction from most birds (curiosity rather than territorial defence)
and find this usually works pretty well (NZ is great as well) though some
species, such as Grasswrens will often just bolt as soon as they realise they
have been tricked.
