The Periyar Tiger Reserve is home to an estimated 500-1000 Wild Gaur, popularly known as “Indian Bison”. They are ferocious looking but shy bovines, and some of the largest in the world. The male bison can weight up to 1000 kg, grows to 6 feet in height and has very dark brown skin. Female gaur are smaller in size and are a lighter brownish black, and the calves are even lighter still.
Gaur are fairly common sightings in the sanctuary while hiking or even from the boat cruises.
