A leopard is a cat with flower-shaped rosettes. It may carry prey into trees to keep other predators away.
Rosettes on the back usually lack a central black spot. Even very dark individuals can show their markings in certain light.
Leopards produce repeated sounds often compared to sawing wood. Both male and female wild leopards vocalised in the Tanzanian study. Their bouts have short opening and closing sounds surrounding a sequence of repeated roars.
A September–November 2023 survey in Nyerere National Park paired cameras and recorders at 50 stations. Researchers identified individuals from coat patterns and extracted calls within ten minutes of photographs. Seven repeatedly recorded leopards provided 26 usable bouts containing 217 roars. Modelling changes in pitch through time distinguished individuals more successfully than summary measures such as maximum or average pitch. The study demonstrated individuality in these wild leopards’ voices.
An extinction-risk assessment has not been added yet.
The leopard’s elusive, often solitary behaviour makes monitoring for conservation difficult. This study tested non-invasive paired acoustic and photographic monitoring. Its authors propose applications to occupancy and individual movements, while explaining that an acoustic population-density estimate at this site would require analysing the wider recording dataset.
