* are there studies of whether a few episodes of playback in a breeding
season harm Owls or other Birds? (there are studies that show that
toe-clipping does increase mortality among Amphibians). It seems to me
that breeding pairs are in constant territorial interchanges, so that a
few episodes of playback would be unlikely to be particularly stressful,
and the fact that the playback is 'defeated' and goes away might even
encourage the pair.
