No they don't, we have an automatic culling system called "run over by cars". We live in a neighborhood of 58 houses, one way in, one way out. The road out front of the subdivision culls about ten a year, from fawns to a nice 19-20" 10 point in the past year. We now have a bear in the neighborhood that I hope to see to take a video on him/her. I think the count is five birdfeeder's now at 45* angles. Only one person has seen it, but lots of sign.
