Yes - saw some of the electronic calls- small, too - usually the ones with rabbits and hares, also have fawns, etc. The mouth-blown hare calls worked here incredibly well, while the cotton tail squeelers don't. The hare sounds more like a fawn, throatier than the higher yet squeeling of a cottontail.
Coyotes around here know we don't have cottontails, I guess. It is now legal here to use the electronics to call wolves and coyotes. Wolves & coyotes are very good at circling to catch the 'wind' on the sound before coming it - similar to younger bull moose during the rut - who will somtimes circle - keeps you moving to intercept them - fun hunting.
