Research overview: trap response, trap-shy and trap-happy behavior to cameras

Animals may change their behavior toward cameras after first encountering them, becoming wary and avoiding the device (trap-shy) or, where lures are used, returning more often (trap-happy), and either response violates the assumption of constant capture probability. This overview surveys evidence for behavioral responses to camera traps, how white flashes, sounds, or human scent at stations can induce avoidance, and how such responses bias abundance estimates if not modeled. It discusses capture-recapture models with behavioral-response parameters, the use of discreet infrared cameras to minimize disturbance, and the importance of careful, low-impact deployment. The overview also connects trap response to welfare and to data quality, since habituation or avoidance distort both detection rates and the natural behavior researchers and photographers seek to document. Recognizing trap response is essential for unbiased felid monitoring.
