In this image, a snow leopard approaches a scent-marking location early in the morning, triggering a camera trap. In this vast landscape, the snow leopard merges with the background that makes it tricky to spot. For this very reason, @snowleopardtrust uses camera traps to estimate snow leopard density and populations. Follow me @prasen.yadav for more photos from India.」10月24日 3時37分
