I have often expressed the opinion that in reacting to a tape the bird
'successfully' defends its territory and thus strengths its possession
and standing in its relationships within that territory. Its not
something I believe in over using, however, the minimal harm it appears
to have on the majority of species would appear to be of no consequence.
We have all heard stories of birds being 'taped out' - I know of one
overseas incident where a warbler sp (can't remember the specifics now)
became so used to the same (only) recording played by visiting birders
that it stopped reacting to it. It obviously recognised the call as a
non-threat and simply ignored it. I think we need to avoid placing human
emotions onto birds and remember that that is what they do - defend
their territories and sing and call to establish their dominance and
maintain their standing. If for a few minutes they react accordingly -
its in their makeup and its what they do best!
All the birders I have spoken to regarding the, almost secret, unspoken
use of playback have described their minimal use of the procedure and
all have been at pains to assure that it is kept to a bare minimum and
for a sighting only, not for prolonged exposure. As pointed out by
others, if there was as much passion and emotion put into stopping
habitat degradation as there is in the use of play back we'd be in a
much better position!
