This is a land of trumpet and songs. The Rhino is the flagship animals for the Sanctuary, which can be seen from the safety of the elephant back, while driving on roads and from a top watchtowers. Besides, one can find elephants wandering in the woodland and frequenting the open grasslands, rivers and glades. Loner tuskers and maknas often come close to Hollong lodge. Herds of Gaur (Indian bison) are easily sighted during early morning and late evening. Deer are well represented here with four species, the chital, the hog deer, the sambar 
and the barking deer (Muntjac). Sambar, the largest of Asiatic deer, is usually seen in a small family group in the woodland and along streams. Unlike chital, hog deer are basically solitary in nature and prefer tall grass cover. The muntjac is small deer of tree forests and specially notable for its loud alarm call- like the bark of a dog. Wild pigs can be seen in small parties around river banks and open grounds engaged in digging out tubers and bulbs. Tigers and Leopards are the main predators in this reserve, though seen rarely by the tourist. Lesser cats of the reserve are Jungle cat, Leopard cat and Fishing cat. Other important animals in the park are the common otter, the small and large Indian civet, Giant squirrel, Indian pangolin, Hispid hare and the Indian porcupine.
