The NGO Aves Argentinas and the Subsecretariat of Environment of the City of Buenos Aires are organizing the ninth edition of a free, family-friendly event that invites you to discover the natural richness of the capital. Next Sunday, November 9, the Costanera Sur Ecological Reserve will be the setting for the festival “Más Vale Volando”.
It is a proposal that combines environmental education, recreational activities, and art to bring citizens closer to urban biodiversity.
An event for the whole family
During the day, which will run from 12 to 6 PM at the Plus Ultra pier (Dr. Tristán Achával Rodríguez 1550, a few meters from the Brazil street entrance), visitors can explore seven thematic stations.
There they will discover insect curiosities, observe birds in freedom, learn about the importance of native plants and fungi, and learn more about the secrets of the reserve.
The activities will be free, open, and without prior registration, designed for all ages. In case of rain, the event will be rescheduled.
The Costanera Sur Reserve: the city’s green lung
The Costanera Sur Ecological Reserve is the area with the greatest biodiversity in Buenos Aires. It hosts more than 2,000 species, including:
- 700 arthropods.
- 400 plants.
- 250 birds.
- 70 fungi.
- 40 fish.
- 20 reptiles.
- 20 mammals.
- 15 amphibians.
This mosaic of life makes the area an indispensable green lung for the city and a key place for nature conservation in urban environments.

Voices that inspire conservation
Cecilia Maqueda, from the Environmental Education team of Aves Argentinas, highlighted:
“To preserve biodiversity, it is essential to spark interest in our native species. Through games, workshops, and gatherings, the Más Vale Volando Festival invites you to discover the treasures of the reserve, promoting an authentic connection that inspires protection.”
Meanwhile, Ignacio Suárez de la Rosa, General Director of Conservation and Environmental Restoration Areas, noted:
“We are proud to accompany Aves Argentinas in this new edition. Birds play a fundamental role within ecosystems, and this festival is an opportunity to revalue the importance of conservation areas in urban environments.”
Art, nature, and citizen participation
The 2025 edition will feature the participation of invited NGOs, who will share their conservation experiences.
There will also be birdwatching outings, educational talks, and the Nido de Arte y Naturaleza Fair, where artisans committed to environmental care will offer products inspired by biodiversity.
