I had the same reaction to Syd's anecdote as John - it suggested the
impact from playback was limited by RSB behaviour.
But I doubt birds can generally distinguish playback (with reasonable
equipment) from conspecifics because songs vary significantly both within
and between individuals and due to degradation in transmission.
Individual recognition has been established in quite a few passerines
so its plausible the RSBs have learnt to recognize the particular songs
on the tape rather than distinguishing it as artificial.
