At least 40 mammal species occur in Pakhui Tiger Reserve (PTR). Three large cats – the tiger, leopard and clouded leopard, share space with two canids – the wild dog and Asiatic jackal. Among the seven herbivore species, elephant, barking deer, gaur and sambhar are most commonly encountered. The commonest monkeys are the rhesus and Assamese macaques and the capped langur. In addition, PTR is home to as many as sixteen species of civets, weasels and mongooses. Commonly seen in pairs is the yellow-throated marten, a small but bold hunter.
