The other day a buddy and me were doing a little coyote hunting, we spooked 4 does and two fawns. They run off about 100yrds and the does began whistling back and fort to each other in short, very loud tweet sounds. I have heard this is the woods before and thought it was a bird but I saw these deer with my own eyes. Just wondering if anybody else out there has experienced this and could this be used as a call to attract deer?
