I’ve hunted Merriams several times NM SD and Nebraska. A ceramic was the call that worked most for me. More specificity the K&H yella hammer with a Purple Heart striker it has bout zero rasp but still has a two note yelp just clear and whiny which is what most of the Merriams hens sounded like. First trip I went thru my vest and it seemed like nothing was getting a response, the YH was the ticket. The Merriams is pretty and so is the country...but I just can’t get used to the farm yard, gay sounding gobble.
