Romerolagus is active mainly during the night and twilight hours but sometimes is seen in daylight, especially on cloudy days and during the mating season. It seeks the warmth of the sun on cold mornings and after cold, heavy rainstorms. It has a trotting mode of locomotion rather than the hopping movements of other rabbits. The droppings are the typical lagomorph ellipsoid but are very small. It utters two cries, a squeak and a high-pitched bark.
Habitat loss is another problem.
In 1969 the total population was estimated roughly at 1,000-1,200 individuals. The pine forest-bunch grass ecosystem on which it depends is being destroyed by conversion to agriculture, overgrazing by cattle and sheep, fire, and encroaching development.
