On Page 70 of the 2013 Game regs, For small game and other wildlife seasons, it lists cottontail rabbit and Snowshoe Hare, daily bag limit= 5/day, see notes. At the bottom of the page, Night Hunting and Hound Hunting During Deer and Elk Hunting seasons, it says that Bobcat and Raccoon may be hunted at night during their established seasons, and Coyote may be hunted at night year round with exceptions. I take this to mean that it's illegal to hunt rabbits at night.
