On a tiger safari, an animal’s alarm call or a line of paw prints may draw attention. Neither is a live location pin. A call may signal that prey has sensed danger; a track records a passage at some earlier point. Both need context before anyone can say what happened.
What an alarm call can tell you
In a 2026 study in southern Nepal, researchers presented an artificial tiger model to chital deer, grey langurs and rhesus macaques, then tested sensors that detected chital alarm calls. The experiment showed that prey can respond audibly to a tiger-like stimulus. It did not verify where real tigers were when calls occurred.
The researchers also noted that leopards may prompt similar alarms. A call is therefore a reason to pay attention, not a way for a visitor to identify the predator, measure its distance or predict a tiger sighting.
What tracks leave behind
India’s National Tiger Conservation Authority field guide lists pugmark trails among signs used in systematic monitoring of tigers and other carnivores, alongside scat, scrapes and sightings. It treats a whole trail as one sign, rather than counting every print separately. That survey method relies on repeated searches by people who know the terrain, not a single mark seen from a safari vehicle.
An earlier NTCA review of pugmark-based counting notes that print shape can vary with the ground and the animal’s gait. Even a print identified as a tiger’s does not, by itself, establish exactly when it passed or where the animal is now. Nor does a path without visible tracks prove that tigers are absent: the field guide allows for a known animal to leave no recorded signs during a survey.
The useful reading is modest. Calls may point to perceived danger, and tracks can document earlier movement. Neither promises a sighting. Let the authorised guide interpret signs in context and follow the reserve’s rules.
