What you say applies to the field study of just about any aspect of bird behavior and is therefore an argument against avian field studies in general. Or am I missing some nuance in your position? The approach here would be the same as in any other field research project: conduct a limited study or 2, drawing provisional conclusions from the results; confirm or disconfirm by further studies (or not, if the interest isn't there); and so on and so on.
So, I guess those of you who rail against the use of recorded calls, are also against even, say, using the human voice to whistle or cluck or coo or any vocalization, any sound at all? That would seem to be the extreme point to which you all are wedded.
A judicious and occasional use of recordings would not seem to be harmful - birds hear all kinds of sounds naturally, from other species and their own, all day long (some at night, too). I'm not advocating 24-hour round-the-clock blasting at 140 decibels, so don't characterize my statements that way.

This point alone, I hope you'll agree, is almost always, an unknown so isn't it better to ere on the side of caution and use old fashioned field craft and patience?

What, are you daft? We've got 150 birds to see today, we don't have time for that...

[I swear, although it was not expressed thus, this is a pretty good summary of the attitude displayed on the first (and last) professionally-lead tour I went on.]
I don't understand how you can make statements such as 'just a form of words' and 'seat of the pants' and expect to get away with it. I asked a perfectly acceptable question. Show me the criteria you use and the results. You can't go around demanding people post proof in the form of verified literature and not expect them to demand the same from you. So, I ask again. Show us the proof of your former statements.
You're just being obtuse now. The argument is about using tape lures on a world wide basis ( there have been indicators to this on previous posts ) not just in your back yard. My point was that if you perform a field study to determine the harm, or lack of it, on birds then you have to encompass the areas in which tape lures, and possible harm or otherwise, occur. To perform a 'limited study or 2' would involve what? A 'limited' study on a single species on one continent and the same on another? I, in my professional life, have seen far too many 'limited' studies shot down before the ink was dry.

One last thing. If you want peer reviewed proof of the last statement I'll gladly provide it. I just hope you either read, or are willing to learn Japanese. I'm not doing all the work.

re post 51: Maybe a good time to cease such primitive antics? After all, we're not cavemen anymore. For a start there are a lot more of us encroaching on fewer birds now, and as the thread title suggests, we are armed with louder, more accurate, more prolonged equipment now as well
you know what. I think quite a few people would really benefit from listening to Iolo's recent speech

Myself included. I'm not stupid enough to think I'm perfect / forever right lol
Can you elaborate on this, please? What are people doing with these perfect shots that makes it so important? Selling them? Showing them off?Photography is so cut throat that everyone is after that perfect shot, even the amateur.
Good point. If the amount of playback used in an area was monitored and controlled (I'm not suggesting that's possible) then it would be ok to use it. But we rely on luck to guess whether we're contributing to something harmful.The problem in popular birding places is not MY responsible (! not this is important!) use of bird calls to lure an individual closer (for watching or photographing doesn't matter in then end), its the summation of other responsible or irresponsible folks that did the very same thing before me and will do it after I have moved on. None of those, including myself, know how frequently the birds has already been subjected to the sound decoy during the day/week, month
