I completely agree (except for the "scaring" part). But the key is "excessive." I would bet a lot of money that the Nocturnal Owl Survey routes are done once, then are not revisited until the following year. Total playback at each site is around 5 minutes (spread over four bouts)...think of it this way, if nesting birds were THAT sensitive to intruders that a few minutes playback causes them to abandon, the species would have been doomed long ago. Done over and over and over again...that's a different story. Randy _________________________________ RF Lauff Way in the boonies of Antigonish County, NS.
