Padmaja Naidu Himalayan Zoological Park (also called the Darjeeling Zoo) is a 67.56-acre (27.3 ha) zoo in the town of Darjeeling in the Indian state of West Bengal. The zoo was opened in 1958, and an average elevation of 7,000 feet (2,134 m), is the largest high altitude zoo in India.
It specializes in breeding animals adapted to alpine conditions, and has successful captive breeding programs for the Snow leopard, the critically endangered Himalayan wolf and the Red panda. The zoo attracts about 300,000 visitors every year.
The park is named after Padmaja Naidu (1900–1975), the governor of West Bengal (1956–1967) and the daughter of Sarojini Naidu, the nationalist leader, poet, and orator who was sometimes called the 'Nightingale of India'. The zoo serves as the central hub for Central Zoo Authority of India's red panda program and is a member of the World Association of Zoos and Aquariums.
The zoo includes an off-display breeding center for snow leopards and red pandas. Captive breeding of snow leopards was started in 1983, with Leopards which were brought to the zoo from Zurich, the United States, and Leh-Ladakh. The red panda program was started in 1994 with individuals from the Cologne Zoo, the Madrid Zoo, Belgium, and the Rotterdam Zoo. In addition to these species, the zoo is breeding the Himalayan Tahr, Blue Sheep, Himalayan Monal, Grey Peacock Pheasant, Himalayan Salamander, Blood Pheasant and Satyr Tragopan.
