The Bañados del Este (Eastern Wetlands) is a vast mosaic of wetlands spreading over 3,200 square kilometers in eastern Uruguay, covering the departments of Rocha, Treinta y Tres, and Cerro Largo. Designated as a Biosphere Reserve by UNESCO in 1976, it is one of the most important wetlands in South America. The reserve encompasses a variety of ecosystems, including freshwater lagoons, salt marshes, swamps, palm groves, and coastal dunes. This diversity of habitats supports an exceptional level of biodiversity. It is a crucial stopover point for millions of migratory birds traveling along the Neotropical Flyway. The area is also home to a significant population of the Pampas deer (Ozotoceros bezoarticus), one of South America's most endangered mammals. Other notable species include the maned wolf and the capybara. The conservation of Bañados del Este is vital for maintaining regional biodiversity, regulating water flow, and supporting local communities through sustainable practices like cattle ranching.

📋 Practical info
Best season
The best period for birdwatching is the southern spring (September to December) when many migratory birds are present. In the summer months of January to March, waterbirds are most active.
Best time of day
Morning hours are convenient when birds become active after the night. Late afternoon also sees the wetlands full of life before dusk sets in.
Etiquette
Move quietly and avoid sudden movements so as not to startle the birds. Stepping on sensitive marsh areas is not allowed to protect the vegetation.
What to bring
Binoculars are a must to identify the many bird species. Rubber boots are recommended as the trails are often wet and muddy.
Getting there
The wetland is located in eastern Uruguay and is accessible via Ruta 9. From there, dirt roads lead to the main observation points.
What to expect
The birdlife is rich, but many species are small and well-camouflaged - take your time for careful observation. The morning silence rewards with the most impressive songs.
