Aves is one of the two founding associations of Natagora, of which it constitutes the ornithological center.

Its purpose is to study and protect avifauna. Bird observations are collected and analyzed to be the subject of presentations and publications (articles, atlases, etc.).

Specialized studies are also carried out by the network of amateur and professional ornithologists, in particular in order to better understand the evolution of the populations of our birds over time.
