Bharatpur Bird Sanctuary, India

Bharatpur Bird Sanctuary is one of India's premier birdwatching destinations, known historically as a major wintering ground for migratory waterfowl. The sanctuary's key advantage is its compactness: a 2-hour bicycle tour (rentals available for $3 USD) circles the main wetland core and routinely yields sightings of waterfowl, herons, and the rare sarus crane, whose population here of 20 breeding pairs represents 15% of India's total.
