This time of year I always hear this PEEP in the woods that sounds similar
to a spring peeper, but I just don't think it is one.  I've heard tapes of
night migrating thrushes making a similar noise, but the maker of this
noise is not moving and I hear it in the day, not at night.  I know peepers
do peep in the fall or late summer, but I still think it's a bird.

Pretty sure I asked this same question last fall, and maybe the fall before
that, and nobody answered, but trying again!
