i would go with rabbit distrees calls for areas not hunted. coyote vocals work better in areas that are hunted more offten, because most hunters use rabbit distress calls and educate the coyotes. mouse and bird distress calls work good for bobcats and coyotes. the owls calls and crow calls work good for crow hunting. some of the other "odd balls" may also work, I have a friend who calls in coyotes with an antelope distress call in s.e. kansas, the closest antelope is a good 500 miles away. any distress call that they havent heard, espically from other hunters, is going to pick there intrest.
