Thankyou for your lengthy and informative response. I
dont often go out of my way to record frogs, but will
if they are there. I do recall a number of occasions
in the UK where I did specificaly go out to record
frogs. There were so many frogs around the edge of
the water (many thousands), that it was difficult not
to step on them. Not a sound issued from their lips
however, the temperature wasnt right for them. I have
also been fooled a number of times into thinking that
a sound was from a bird when it has turned out to be a
frog/toad and visa versa. Good luck with the CD.
