A female tiger and her cubs have been photographed roaming a north-Indian river valley by hidden camera traps.
The images were taken in the Kosi River corridor, part of remote India’s Terai Arc Landscape.

“Knowing the tiger numbers and their movement routes in a corridor would provide a sound database in taking decisions on developmental activities within and around the corridor,” said World Wildlife Fund coordinator Joseph Vattakaven in a press release.
The Bengal tiger is an endangered Indian subspecies called Panthera tigris tigris. According to the latest population survey by the International Union for Conservation of Nature, no more than 2,500 Bengal tigers exist globally.
India harbors most of them with an estimated population of 1,706 tigers in 2011 — up from roughly 1,411 tigers in 2006. The boost to the population and its density (about 15 tigers per 39 square miles in the Kosi River corridor) can be deceiving, however, as the big cat’s habitats are shrinking.
