Picture a golden winter morning. Fog lifts off mirror-calm water. A flock of bar-headed geese skims past at eye level; a marsh harrier quarters low over reed beds; painted storks clatter back to their nesting trees. Keoladeo National Park (formerly Bharatpur Bird Sanctuary) is that rare thing: a human-made, human-managed wetland that turned into one of the world’s great bird stages—so vital it earned UNESCO World Heritage status in 1985.
