Bobcats are solitary (live alone) whereas coyotes are social (live in groups) but both species are territorial. Although coyotes and bobcats are capable of fighting to protect their territories, these species avoid fighting at all costs. Injury is serious for predators who rely on their bodies to protect themselves and to capture prey for themselves and sometimes their offspring. Instead, carnivores mark their territory with urine to define and communicate the boundary of their territory to competitors. Their acute sense of hearing and scent not only help these predators find prey but also to communicate and avoid risky conflict. These species have distinct individual scents that usually do not go unnoticed by other individuals of the same or other species. Shown in this entry are a sequence of photos of wildlife communicating through scent within the span of about 3 hours.
