Yes, I believe such studies exist, where birder densities are higher
(USA, UK), but no, I don't have the reference(s). We've had this
discussion on the list before (about tapes & spotlighting). Many
birders say "Prove it's harmful, or I'll continue on with what I'm
doing.". I prefer to be more careful than that. Whatever happened to
the cautionary principle?

Well both, but I did say it was MY opinion. What's the point collecting
stamps (getting the birds in with a device)? I don't find it appealing,
but some do, so they should justify their actions. You question my
interest in bird welfare - I question the interest in bird welfare of
anyone who uses tapes simply to twitch birds.

In my experience in various fields of endeavour, many people give little
or no consideration to the consequences of their actions. Recreational
birding is not intrinsically benign, & it is blinkered to think anything
else.
Yes, I'm dogmatic.
