Research overview: scent-marking and communication behavior on camera

Wild cats communicate through scent-marking, spraying, scraping, cheek-rubbing, and clawing, leaving signals at conspicuous sites that they revisit, behavior that camera traps are uniquely positioned to document. This overview surveys how researchers place cameras at marking trees, rocks, and scrapes to record this behavior, exploiting the fact that territorial cats return to such sites to boost detection of species like cheetahs, jaguars, and tigers. It discusses what camera footage reveals about marking frequency, the individuals and sexes involved, seasonal and reproductive patterns, and how scent communication structures territories and mating. The overview also notes the practical survey advantage of marking-site cameras for capturing identifiable images and increasing recaptures. By turning communication hotspots into observation points, camera trapping illuminates a normally invisible dimension of felid social and spatial organization.
