Situated in the Kangra district of Himachal Pradesh, the Pong Dam wildlife sanctuary covers almost 307 sq km in area. The largest wetland in India, Pong Dam also serves as a sanctuary to the largest population of migratory birds, including the bar-headed geese and a number of endemic species. Some of these birds arrive after travelling thousands of miles across the world. The birds will have to fly through some of the highest mountain passes in the world to reach the safety of Himachal’s Pong Dam. But where the birds fly, the temperature is minus 40 and the air is thin with almost no oxygen. Yet amazingly, these powerful birds climb higher, steadily flying for hours to cross the frozen mountain passes. The film showcases one of the toughest and the most dangerous migrations in the world. The Pong Dam resounds with the cacophony of bird sounds and turns into a hive of activity. With food in abundance, the birds feed peacefully: Pochards, Northern Pintails, bar-headed geese, coots and various ducks all sharing the placid waters of the Pong Dam. Built in 1973, to provide electricity, needed for development along with water for the people and farmers, the Pong Dam has been adopted by these migratory birds. This damn is a unique example of human-animal relations - a dam made to benefit humankind has become a crucial system for other life forms, too. An oasis of hope, benefiting migratory birds and animals, paving a path for harmonious co-existence and a sustainable future.
