The good things about those open reed distress calls, and what a lot of people don't know, is that they are capable of making a wide variety of calls and sounds that are not necessarily limited to a rabbit distress sound. For example, on my rubber rabbit call, I can manipulate the reed with lip and teeth pressure as well as mouth positioning on the reed to make many animal sounds. Cottontail distress, deer grunt, deer bleat, fawn bleat, pup distress, elk mews, bird distress, some barks and howls (though not very good IMO), whines and whimpers, are some examples. As with any call, the more you practice the better you get. Good Luck and God Bless, Steve
