Russ & all, Birders or photographers who use playback or otherwise disrupt nesting birds in sensitive situations are not necessarily "bad apples." This is commonly done by relatively new birders who just get excited by a new device or a new trick that helps them to see more birds than they have seen before. Probably most of us "old-timers" or "middling-old-timers" on OBOL have gone through that stage at some point in our birding life. I've done that kind of thing myself (for example when I first discovered pygmy-owl imitations), before it occurred to me that there are some situations in which these techniques could be harmful. My purpose is bringing up the status of the catbirds at HMSC as a reason for exercising some restraint was aimed at birders who are going through that stage, and just have not yet given much thought to the possibility of birding impacts. Certainly there are going to be a few crusty folks who are determined to go birding however they damned well please, and will thumb their nose at any mention of the ABA code of ethics. There's not much we can do about those folks. Fortunately their numbers are fairly small, so this limits their impacts. I'm much more hopeful about reaching newer birders who use OBOL as a source of information on where to find uncommon birds. With the confirmation of nesting catbirds at HMSC, it seemed likely that these birds could draw the attention of large numbers of folks who are relatively new to birding, and who might even get the idea (from recent postings) that further documentation of these birds is needed. Indeed, with the growing push for "citizen science," we might be reaching the point where most incidents of disturbance by overzealous birders stem not so much from a "selfish" desire to pad personal lists, as from an earnest hope that individual observations will somehow contribute to "science."
