I think lawnmowers do as much harm to the babies as coyotes. I hate to admit it, but I know I have killed more babies with a lawn mower than with a gun or hitting them with my vehicle. Not sure if it is the noise or what, but it seems like they are drawn to the mower. I feel like a turd whenever it happens. Just plain horrible feeling. One time I was mowing and had spotted a single bunny. I was extra cautious. The way the lawn was setup I had to pass it half a dozen times. I carefully avoided it the first five. That last pass I thought I was good to go and the little thing decided to move. Ugh. Poor little thing. I still feel bad and that was 5-6yrs ago.
