Usually the screaming rabbit in distress works, if they havent heard that one a lot.
Fox, or canine Puppies in distress is a good one, that isnt used much . Deer fawn distress bleats, and turkey calling are two that are natural attracters in certain areas in the spring. Sparkman
personally i have a FOXPRO and love it! i mostly have used the cottontail distress with some success as far as bring them in. i just need to learn to be patient!! from what i hear the woodpecker is suppose to be a real good sound also. i'll have to try it sometime.
