| Like many rabbits, Robust Cottontails are crepuscular, doing most of their foraging at dawn and dusk. Rabbits have large eyes and see well in dim light, so moonlit nights may also find them out nibbling grasses and other vegetation. They have a good predator-detection system - their large, swiveling ears. If threatened, they slink, ears back, or zigzag at top speed, to a den, brush pile, or other shelter. Many do not escape: they are staples in the diets of many birds and mammals, including humans. Their high reproductive rate compensates: females can have several litters a year and may produce as many as 35 offspring annually.
Rabbits are not thought of as noisy animals, but a frightened rabbit can emit a loud, high-pitched distress cry, and females with young have been heard to grunt if an intruder comes near her nest.
