Udawalawe National Park
Udawalawe is an important habitat for Sri Lankan elephants, which are relatively hard to see in its open habitats. Many elephants are attracted to the park because of the Udawalawe reservoir, with a herd of about 250 believed to be permanently resident. 
The rusty-spotted cat, fishing cat and Sri Lankan leopard are members of the family Felidae present in Udawalawe. The Sri Lankan sloth bear is seldom seen because of its rarity. Sri Lankan sambar deer, Sri Lankan axis deer, Indian muntjac, Sri Lankan spotted chevrotain, wild boar and water buffalo are among other mammal species. Golden jackal, Asian palm civet, toque macaque, tufted grey langur and Indian hare also inhabit the park. A study conducted in 1989 found that considerable numbers of golden palm civets inhabit the forests of Udawalawe. Five species of mice also have been recorded from the park. The endemic Ceylon spiny mouse, known from Yala National Park, was recorded in Udawalawe in 1989. Indian bush rat and three species of mongoose are also recorded in the national park.
Birds
Painted storks are among the many water birds that migrate to the park.
Udawalawe is also a good birdwatching site. Endemics such as Sri Lanka spurfowl, red-faced malkoha, Sri Lanka grey hornbill, brown-capped babbler, and Sri Lanka junglefowl are among of the breeding resident birds. White wagtail and black-capped kingfisher are rare migrants. A variety of water birds visit the reservoir, including cormorants, the spot-billed pelican, Asian openbill, painted stork, black-headed ibis and Eurasian spoonbill.
The open parkland attracts birds of prey such as white-bellied sea eagle, crested serpent-eagle, grey-headed fish eagle, booted eagle, and changeable hawk-eagle. Landbirds are in abundance, and include Indian roller, Indian peafowl, Malabar pied hornbill and pied cuckoo.
