I hesitate to post this, being fully aware of ethical concerns, but I will
be leading a field trip for the MOS Conference this year into rail habitat.
 Since it's an afternoon trip, when the birds are unlikely to be calling, I
think it may be justified to try playback to entice the birds to appear.  
Regrettably, however, I am unable to find any use-able recordings.  While
all the relevant recordings are on the Stokes CDs, there's that pesky
announcement of species at the beginning.  And, so far, my attempts to find
anything on line have been fruitless.

If you can suggest some solutions, please reply off-list.  And, if I'm WAY
BEYOND the ethical pale, please let me know.
