Had em come running to fawn distress calls before, some NC biguns. Also have listened to em and tried just making a noise like they made, seems to be a noise they make when they are unsure of something. it may not attract them but if they are clase and you do it it does calm them, will make em come up on their hinds to get a look at you. I think anything in distress rabbits, fawns.... should make em wonder. Never called one in season though I might add, round here bear season is Nov - Dec. I have only had luck calling em during the early bow, probably the reason the fawn distress works as fawns are around.
