The brush rabbit is slightly smaller at 11 to 13 inches long, weighs between 1.25 to 1.8 pounds, and has brown fur. A good sign that rabbits are present is coarse, circular fecal droppings or pellets found scattered over an area. They are seldom found in dense brush or woodlands. Within their preferred habitats, jackrabbits are quite adaptable and inhabit areas around the fringes of urban and suburban developments, green belts, golf courses, parks, airports, and agricultural lands. In California an average density of about 1.2 jackrabbits per acre is typical, but during periods of high reproduction this number may increase.
Jackrabbits depend on speed and dodging to elude predators.
The breeding season runs from late January through August, although breeding is possible during any month of the year where winters are mild. Litters average between 2 to 3 young, with as many as 5 to 6 litters per year. Young jackrabbits are born fully furred and with their eyes open. Within a day they can move about quite rapidly. The food habits of jackrabbits are highly variable, depending on location and the availability of appropriate plants.
