Aves Argentinas has been working to protect this species for years. Patagonia National Park became a protected area because of this critically endangered grebe. Photo by Alberto Franke.

Its melodious song is its curse - the species is being traded to extinction as it is sold as a cagebird. Aves Argentinas is working to end its illegal trade. Photo by Matías Romano.

This species has been downlisted to Near Threatened as it is no longer estimated to be undergoing very rapid population declines. High levels of mortality of this species are reported from longline and trawl fisheries in the South Atlantic but the Albatross Task Force is working to stop it. Photo by David Cook.

These amazing migratory birds spend their winters in Argentina and their summers in the US. In the 90s, Aves Argentinas stopped the mass-poisoning of nearly 6,000 individuals as a result of pesticide use. Today its population trend is stable. Photo by NPS/Patrick Myers.

This beautiful endangered bird lives in the grasslands of South America. Currently it only occupies 10% of its original distribution. Aves Argentinas manages the El Bagual nature reserve which aims to protect it. Photo by Ángel Prato.
