The natural landscape of the Zoo attracts several migratory as well as resident birds. It is the first Zoo in India to have animals arranged in Zoological order in open enclosures. Such open enclosures in near natural ambiance make animals feel at home. The mode of display is either open moats or cages. Both wet moats and dry moats are used as barriers for confining the animal in the enclosure. There are around 159 enclosures in the Zoo. Zoo has various natural advantages like the location of the Zoo, availability of water, natural surroundings, and display of animals in open moat enclosures. Diet charts for different species of animals have been formulated after many observations.
