Yes, many times, but not often in recent years. Last time I heard a rabbit scream was at night in the E. Kootenays of British Columbia and I'm sure it was an owl grabbing a snowshoe hare. I grew up rural and hunting a lot in E. WA when jack rabbits and cottontails were plentiful, plus we raised domestic rabbits that sometimes will scream when you merely pick them up. I remember a high pitched cottontail at the old Hover town site that we cornered in a basement and it screamed a squeeky note I will never forget. I don't like the sound, though have called a lot of critters with it.
