It's called....The Lil Pekker, produced by Kettle Creek Calls
google it, I have killed several fox over this call in a very short time this season. Versatile, excellent sounding, and WILL NOT freeze up...it's the only woodpecker distress call I will use.
Good luck. /ubbthreads/images/graemlins/grinning-smiley-003.gif
