Rabbits run in circles, which is why beagles work so well.
Beagles
When a beagle jumps a rabbit, the rabbit usually circles back near where it started. Stay put and watch.
Without dogs
Walk slowly, stop often and kick brush piles. Rabbits often hold until you pause.
Snow
Fresh snow shows tracks and makes rabbits easier to spot.
Healthy rabbits only
Never take a rabbit that acts slow or sick.
