Turkey call:  The Yelp

Turkeys use 4-10 note series when trying to find other turkeys.  They have been known to yelp in longer or shorter sequences at times.  The "kee-awk,kee-awk" yelp (or two-note yelp) can be raspy to high-pitched.  The hen yelps are faster in cadence and not as deep throated as gobbler yelps.
