Padmaja Naidu Himalayan Zoological Park-West Bengal

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), daughter of Sarojini Naidu. 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. In January 1972, the park became a registered society, with an agreement that maintenance costs would be shared by the central and state governments. In May 1993, the park was transferred to the West Bengal Department of Forests. The park was renamed in 1975 when Indira Gandhi, the Prime Minister of India, visited the park and dedicated it to the memory of Padmaja Naidu.
