Buenos Aires has many options for nature lovers; not least in the great variety of bird life native to the city.
Riverside areas along the Rio de la Plata, public squares and parks, and protected reserves all attract birdwarching enthusiasts and experts. The greatest variety can be found at the Costanera Sur Ecological Reserve, where 320 native and migrating species have been spotted. The reserve is the most important in the city and one of the most important urban reserves in the world. It has been declared an Important Bird Area (IBA) by Birdlife International and Ramsar, the convention for the protection of wetlands.
Experts lead a guided birdwatching circuit on the second Friday of every month, starting at 9am at the entrance to the reserve in Calle Viamonte. You can reserve a place by emailing email@example.com.
