I can agree with most of what Ken has clearly stated. As I indicated in my original post, I see no problem with valid scientific studies, censuses, or instructional matters involving bird identification, appreciation, or even photography methods. I also agree that "breathtaking photographs" can turn many on to the wonders of the natural world. A caveat here is that these photos bring personal financial gain to this particular photographer, which is expected and deserved, but which can unfortunately serve as an excuse for large numbers of people to invade certain habitats and inundate them with recordings in an attempt to make money. I agree further that, at the present time, there are no demonstrable effects of the relatively few playbacks being used for non-professional purposes. However, as Geo has quibblingly pointed out, the use of electronic gadgetry is growing exponentially, and I am concerned that a culture of "anything goes, anytime" may have deleterious effects in the future. As an acknowledged leader in the field of conservation, Cornell sets many standards, and I am asking if any consideration is being given to this potential problem. It is my opinion that the potential for abuse is great and that an open call for restraint in the general use of playback "tapes" is warranted.
