Aves Argentinas / Asociación Ornitológica del Plata (in English: Argentine Birds), is an Argentine non-profit environmental organization dedicated to conservation and birdwatching.

Created in 1916, it is the oldest environmental organization in South America.

The organization is involved in the re-introduction of the red-and-green macaw (Ara chloropterus) which has not been recorded in Argentina for some years.

It is listed as critically endangered in Argentina, and listed as a ″a species of global least concern″ on the IUCN Red List.

The first birds were released in 2015, in the Iberá Provincial Reserve (Spanish: Reserva Provincial Iberá) in north-eastern province of Corrientes[1]
