Kolkata, a bustling city in eastern India, is known for its rich cultural heritage and urban development. However, amidst the concrete jungle, lies a hidden treasure of wildlife habitats. The city is home to several sanctuaries and parks, providing a haven for various species of animals and birds.

The Sundarbans National Park, located on the outskirts of Kolkata, is a UNESCO World Heritage Site and the world's largest mangrove forest. It is home to the royal Bengal tiger, saltwater crocodiles, and a diverse range of avian species. Other popular wildlife attractions include the Banobitan Biodiversity Park, where one can spot peacocks, deer, and reptiles, and the Kolkata Zoo, housing animals like the Asiatic lion, elephant, and giraffe.

The conservation efforts in Kolkata have also led to the revival of the once-endangered species like the house sparrows, which can now be found in abundance in the city. With its unique blend of urban and natural landscapes, Kolkata offers a unique experience for wildlife enthusiasts and nature lovers alike.
