Parrots and parakeets are found everywhere in South American forests. For me, it seemed nearly impossible to identify them from the little details, but thanks to Bruno Tredez, it came out nicely.
I previously published images of the Hyacinth macaw, one of the most impressive large parrots I found in Brazil in 2007.
