There are four ranges in Wayanad Wildlife Sanctuary in Kerala: Sulthan Bathery, Muthanga, Kurichiat and Tholpetty. You can see lots of big animals at the sanctuary, including bison, elephants, deer, and tigers. It's also home to some cool birds.
In addition to being part of Nilgiri Biosphere Reserve, Muthanga Wildlife Sanctuary has great biodiversity. It's a Project Elephant site and has a lot of pachyderms roaming freely, but it also takes into account the lifestyles of tribals and others living nearby. There's a lot of deer, monkeys, birds, and tigers here.
