Corbett National Park is a divergent and full of extremities in its habitat as well as in its flora and fauna. This corbett national park is the treasure trove comprising riparian habitats and dry riverbeds. This location is the residence of woodlands and open grasslands, forest-grassland edges, reservoirs and mountainous terrain.
More than 586 species of resident and migratory birds have been categorised, including the crested serpent eagle, blossom-headed parakeet and the red junglefowl — ancestor of all domestic fowl. 33 species of reptiles, seven species of amphibians, seven species of fish and 36 species of dragonflies have also been recorded.
Leopards are found in hilly areas but may also venture into the low land jungles. Small cats in the park include the jungle cat, fishing cat and leopard cat. Other mammals include barking deer, sambar deer, hog deer and chital, sloth and Himalayan black bears, Indian grey mongoose, otters, yellow-throated martens, Himalayan goral, Indian pangolins, and langur and rhesus macaques. Owls and nightjars can be heard during the night.
In the summer, Indian elephants can be seen in herds of several hundred. The Indian python found in the reserve is a dangerous species, capable of killing a chital deer. Local crocodiles and gharials were saved from extinction by captive breeding programs that subsequently released crocodiles into the Ramganga river.
