Exercise 2 solution (sample answer)

"I would rather not play the recording. The source I read lists playback among practices to limit, because it can stress birds and draw them out of cover, and it is worse with a rare bird that many people may already be disturbing. Could we wait quietly a few metres back for ten minutes instead? If it comes out by itself we get a better, more natural photograph, and if it does not we have not harmed it."

Good answers are friendly, give the reason, and offer a practical alternative (patience, distance, a hide, or a longer lens).
